Digital battery

Since 1992, benefits of Sony lithium-ion batteries to achieve industrialization since, under its high specific energy, long life, no memory effect, safe, reliable and can quickly load and unload, lithium-ion batteries are become the new power technology recent years, development of hot spots. Lithium-ion Dell Latitude D810 battery is the green environment-friendly pollution free rechargeable batteries meet environmental needs of national energy today in all areas of use of life is increasing rapidly. Currently, lithium-ion has been widely used in mobile phones, laptops, digital cameras, MP3 and other electronic products, many of replacing nickel-cadmium batteries and nickel-hydride batteries, metal, in applications such as most as an exclusive Jiucheng. In addition, lithium-ion battery electric vehicles in recent years, and some other high power batteries have started to come into practical use.

 

Before 2000, the Japanese lithium-ion batteries dominate the world, and production accounting for about 95%. In recent years, with China (including Taiwan) and the rapid rise of South Korea, the Japanese show a single model has been gradually broken. Market Share of Japanese lithium-ion batteries has fallen below 60%, about one third of the world to form a pattern. Although in 2008 the global financial crisis hit, but rechargeable batteries, regardless of volume, sales were both up there on the rise, but this year will continue to be a difficult year. The future, the rapid development of a variety of electric vehicles, lithium-ion batteries will become a major driving force for progress.

 

The status of lithium-ion batteries can not be shaken

 

In 1989, the small size of the room-type lithium batteries to achieve a practical use. However, in the summer over a series of batteries for cell phones use lithium overheating in 1989 and caught fire due to an accident in early 1990, the industry uses a cylindrical, hp F2024B battery Rechargeable lithium had a negative attitude towards the prospects for practical application. However, Sony has specialized in the manufacturing technology of energy batteries Sony (Sony Energy Tech) ’s courage to break the deadlock, the same year in February announced the lithium-ion rechargeable battery reached a practical level.

 

Cause of the accident caused by lithium batteries that will be used as anode material for lithium in the charge and repeated discharge, the cathode is the formation of dendritic crystals, so a short - circuit between the positive and negative electrodes, emitting smoke and fire. The lithium-ion rechargeable battery in the positive and negative do not use lithium metal and its positive use of LiCoO2 (lithium cobalt) alloy material, the negative electrode material using carbon type of coke. This ensures the safety of the Dell KD476 battery to reach the cylinders of lithium type.

 

However, the practice at the beginning of the performance of lithium-ion battery was not significantly better than the main competing products - Ni-MH rechargeable batteries. For example, in early 1993 lithium-ion rechargeable battery unit volume density of energy 220Wh / L (This is a diameter of 65mm and 18mm × length value of the cylinder type battery, the same below ), just over nickel-metal hydride batteries 180Wh / height of approximately 20 L%. In addition, lithium-ion rechargeable batteries, there are many shortcomings, such as “there is no tension between compatibility and dry,” the difficulties of load control “,” high resistance, current high charging and discharging can be, “difficult to parallel, it is difficult to realize large capacity battery” and so on.

 

However, mobile phones and video cameras and other manufacturers of lithium-ion rechargeable VGP-BPS9A/B battery features lights a little low. Energy density per unit weight of these terms, lithium-ion battery than nickel-metal hydride rechargeable batteries is about twice as high as up 115Wh/kg. In other words, the same energy capacity, lithium-ion battery reduces the weight by about half. Thus, manufacturers of portable equipment, under a special favor in 1991 after the adoption of lithium-ion rechargeable batteries have the product market, and very popular. Since then, Matsushita Battery Industrial Company in 1992, Japan’s Battery in 1993, Sanyo Electric, Hitachi and Canada Moli Energy (1990) were commissioned in 1994, established the lithium-ion rechargeable batteries in portable electronics on the market can not shake the position.

 

Since 1990, lithium-ion rechargeable batteries have been largely along the high density and secure the development of these two main lines. To promote the products of small and light, manufacturers of portable electronic equipment urged to improve the energy density of batteries. However, the denser the smoke of the fire, the greater the risk. Incident does not happen again! The summer of 1989 fire incidents in the apple A1060 batteryof technical persistent spirit: If an accident, the use of materials of lithium battery will be the future is doomed.

 

To this end, in lithium-ion rechargeable batteries, the beginning of practical use, the battery manufacturer for its implementation will be known as the “most protective” of strict security measures. In order to fall in poor operation of the battery due to excessive discharge / over charge of the state can ensure security, the manufacturer of the battery configuration of the three types of security architecture: PTC (positive temperature coefficient) thermistor valve Security diaphragm. When mounted detected an abnormal temperature, the possibility of cutting off the electric mode of the load cell to avoid the danger.

 

In addition, development of mobile phones, cameras, computer hardware manufacturers have to ensure mobile security battery has played an important role. At that time, all the hardware manufacturers have established programs for acceptance testing, such as nail prick test, high temperature / low temperature test, as well as heating pan tests. Equipment manufacturers will be a series of tests based on the results raise the existing problems in the toshiba PA3591U-1BRS battery manufacturer, on how to improve the cell structure and design of safety circuits, and so many points of view. In the hard work in close cooperation with the early 20th century during the period, lithium-ion rechargeable batteries are no longer a major accident, the market is developing very well.

 

Improved security, the lithium-ion battery energy density of the battery continues to increase. The beginning of practical use in 1990, lithium-ion battery density of energy per unit volume, but 190Wh / L to 19 years later, in 2009, this value increased about 4 times, reaching 740Wh / L. But the same period, the microprocessor clock frequency up to 100 times the capacity of the DRAM is increased 250 times. Therefore, the rechargeable battery is also frequently called progress is too slow.

 

Increased energy density is mainly based on positive and negative materials to improve hp Pavilion dv4 battery of structural adjustment and improvement of manufacturing processes such as leather and complete been piecemeal. 19 years, there have been three times the material of great change, many, many times the energy density of high speed. The first took place in 1994 and 1995, the anode material of coke in a class of carbon materials, carbon, graphite type materials, this change so that the energy density has increased by about 20%. In the following 8 ~ 9 years, has maintained a positive use of LiCoO2, cathode graphite using a combination of such carbon material. The Change 2nd occurred in 2002 and 2003, the LiCoO2 cathode material in the LiCoO2 and Li (Ni-Co-Mn) O2 mixture of materials, the energy density of about 10%.

 

Is currently in 3rd period of change. The anode material is the reform candidate materials, including the type of silicon alloy, tin alloy and lithium three categories. An alloy of tin came in practical use. Sony introduced after the spring of 2005, the group of device battery has started to use this material. 14mm (diameter) x 43mm (length) of the unit cell volume of the energy density can reach 478Wh / L, compared to traditional materials, an increase of approximately 20% of the Dell Latitude D410 battery.

 

In January 2007, Matsushita Electric Industrial and Matsushita Battery Industrial through the use of certain types of materials such as alloy anode material, with successes to 740Wh / L energy density per unit volume. The company did not disclose the specific circumstances of this alloy material, until March this year, not mass production, it is expected that the near future or will be put to practice. In addition, the type of alloy of silicon and metal lithium as a cathode can significantly increase the energy density of batteries are also on trial.

 

After 2006, laptops and mobile phones and other products used in lithium-ion rechargeable batteries, the recurrence of an abnormal occurrence of heat, the potential fire hazard. Sony, Matsushita Battery Industrial, Sanyo Electric and other battery manufacturers have a large number of recycling batteries. The reasons are said to be mixed in the process of manufacturing powder metal, it is said to be load and unload equipment manufacturers in the management of misconduct. And equipment manufacturers face the cons, up another case of malfeasance.

 

In fact, the real reason not yet been identified. To this extent, must be carefully verified reason, understand that the resurgence ‘accident, the future is doomed, “the gravity of technical staff to learn both sides to ensure safety at all costs try to develop the spirit of time, work together to move forward together.

Some basic methods

 

First presents the basic methods, these methods, you may already be familiar with, but if the flexibility of demand, will greatly increase battery life.

 

1, using energy saving mode mobile phones

 

Take time to understand the interface of your smartphone, you will find the settings can be saved by changing the Laptop battery. Note that these parameters are related to many aspects of the use of mobile phones, it may be in different parts of the interface. But for most cell phones, such as Windows Mobile and BlackBerry mobile phones, the option in the Settings menu.

 

We must reduce the brightness of the screen by default, because the climax will consume more energy. But also shorten the time fire background. Although this may sometimes make you feel very cool, but its benefits are obvious.

 

2 for your cell phone to find stuff online

 

For example, there specifically for a new generation of Apple’s iPhone 3G page on how to save electricity. In addition, there are few manufacturers not to provide useful skills, like the BlackBerry and Windows Mobile website.

 

3, if there is an opportunity to take time to load

 

The use of mobile phones are lithium-ion IBM ThinkPad T40 battery, so it is quite possible and even recommended. If the conference room of the outlet or load terminal of the airport, to take full advantage of every opportunity to recharge their cell phones. Recharging while driving is a choice, you use a car charger for mobile phones directly from the handset manufacturer or carriers to search, you can also purchase companies such as APC provide a universal charger.

 

4, using calls, rather than e-Mail

 

In the cellular network, the data connection used to connect the battery is the voice of two to four times. For simple communications, call or send text messages rather than e-mail.

 

Effective management of your software

 

Many of us tend to have used an operating system. And the request to make your smartphone to make it useful and interesting. But regardless of the operating system or applications, will be the exhaustion of VGP-BPS9 power, forcing them to manage and reduce their energy consumption.

 

5, upgrade the operating system

 

Maximum power consumption is the operating system. In each version, manufacturers are still improving energy consumption, in a timely manner to update your operating system.

 

6, using a simple ring

 

Need to use the cell phone with music ringtones processor, leading to consume more energy. A simple, standard ringtones should not be such a treatment.

 

7, minimize the use of the push

 

The most popular is probably the smart phone applications, push e-mail, which requires little time to check the phone messages. This consumes much energy, and you can use settings on the server or the phone itself is set to adjust the cell phone every 10 minutes or half an hour to check the information first. Clearly, this must become accustomed to the use of instant messaging users to coordinate, but on saving hp Pavilion dv4 battery power is really worth doing.

 

In addition to push e-mail, there are a number of other applications and Web services such as instant messaging, navigation tools and stock, news, sports and weather information will be updated periodically. You may not be aware that if you ESPN updated every five minutes, will soon complete consumption battery power. So when you do not use these programs and websites where close.

 

8, weakened garrison functions

 

When news is old, do you really need to phone to vibrate? New messages for the closure of the auditory or visual alarm, or at least have the choice of closure, for example, to retain only your boss and inform parents.

 

Effective management of your hardware

 

In the past, the mobile phone is only a radio for voice calls. Now, in addition to cellular voice daily and data services, wireless, smart phones have Bluetooth, Wi-Fi radio and even GPS.

 

9, turn off the radio does not use

 

The radio is on, even without the use of considerable VGP-BPS13 energy. Learn how to switch off the radio smartphones. For example, for most Windows Mobile phones, if the hold the home button and keep for a while, a dialog box is displayed on mobile phones, you can open this dialog, or turn off the radio.

 

10, note that the time to call

 

When there are too many people trying to access the cellular network, mobile consumption of energy will be even more grande.Malgré this, you may also be reluctant to 3:00 call or answer the phone, but if you’re in the western region of a night owl, 7:00 is what one might call the best time for the eastern region.

 

11 know where you live

 

Studies have shown that the network will be a place where electromagnetic interference to become unstable. This means that in the outdoor park in the mail or call electric hospital less.

 

Similarly, the poor areas of radio coverage will be unstable. If you are in the areas covered by bad guys and you do not like SMS, then turn off your radio.

 

12, using low-speed network

 

Using HSPA or EV-DO as well as using EDGE or 3G services, such as 2.5G services, 1xRTT need more power. All applications require a maximum speed, you will notice in May 2.5G and 3G services, the major differences, such as checking your email. Some phones, such as the Apple iPhone 3G, you can jump to a network access low speed, thereby saving the Dell Inspiron E1705 battery power. If your phone has this feature, at the appropriate time to use it.

 

13, using a wired headset

 

Bluetooth headset to use their own needs for radio frequency use the battery. Using the wired headset does not use a separate radio frequency, will make your cell phone to use longer. And using a wired headset call quality is better.

 

14, using self-closing feature

 

Some phones, like BlackBerrys, mobile phones within the time specified, close parameters. Phone automatically turns off at 11 am, at 7:00 to open. In this case, you do not have to worry about the.

 

Battery Maintenance and Repair

 

On the way to maintain the battery some outdated ideas still exist for the old nickel-chromium batteries, power is often proposed that ion battery depletion, after full power, but for lithium today - The practice should not be so, and people still, and even some instructions in the user manual is wrong.

 

So here are some tips to ensure more usage time of battery life.

 

15, early and often responsible charge

 

Experts suggest that as far as possible not to pay very little when it is charging. But there is one exception, every few months they should be on your battery is completely discharged, then recharge. In fact, this does not apply if the battery life, but you can reset your phone to load the firmware to provide a more accurate value.

 

16, to keep the battery cool

 

Do not put your cell phone hot place. Experts said this would reduce the capacity of the storage battery.

 

What’s happening in the money

 

17, a spare battery

 

If you want to use the phone for a long time, then buying a laptop toshiba PA3465U-1BRS battery. Depending on your phone model is different from the battery usually costs only U.S. $ 10-30.

 

18 for long battery life

 

Such cells are usually caused by telecom operators and handset manufacturers to sell, they should be larger than the standard battery, this may be filled with the entire phone. But the cell can use a longer time, so you will not be forgotten to worry about a battery backup.

 

Depending on your phone model is different from the price of this long battery life of 20 to 30 dollars.

 

Note that the two techniques above do not apply to Apple’s iPhone because the iPhone battery cell phone is not replaceable.

 

19, carrying a portable rechargeable battery

 

These products are now endless. For example, Medis 24-7 Power Pack fuel cell technology to recharge the apple M8403 battery while the solar charger Solio provides. Portable battery using technology more conventional batteries, such as the Big Wave Power in EnergyPORT. Completely full-power portable battery for your cell phone offers 30 hours of battery life.

 

20, buy a spare battery

 

Battery backup as a method of last resort, and turbo charge manufacturers Cellboost like to buy. This battery lighter, cheaper, and not burden of bulky battery, they are reserved for emergencies.

 

Obviously, if you follow this advice, you may not need emergency aid. Pay more attention to your cell phone battery, they will work longer.

1. Battery invention inspired by frog legs

 

“Green” has become the most popular vocabulary. Environmental protection is at the heart of “new energy”, while the core of the new energy is the battery. Recently, the “2009 Electric Vehicle Industry Development Forum held in Beijing, the technology of pure electric vehicle Laptop battery that the meeting focused. In fact, pure electric vehicles used in battery, all power battery capacity of the largest categories, but also the highest technical difficulty of a battery. His ancestors there are over 200 years, has already emerged. Over 200 years of development history, they were in the work “hard”.

 

The birth of the battery based on people’s access to stable and sustained for present needs. However, the invention of the stack is derived from the anatomy of a frog’s experience generated by inspiration, a bit accidental.

 

Portrait of the Italian anatomist Luigi Galvani, because the anatomy of the frog, when he discovered the “bio-power” and famous, please note that the lower part of this portrait of a half-frog

 

One day in 1780, the Italian anatomist Luigi Galvani (Luigi Galvani) do dissections of frogs, hands held VGP-BPS10A/B all kinds of metallic equipment, inadvertently touched the thigh of the frog at the same time, the contraction muscles of frog legs at once a moment, as the stimulatory effect, and if only a metal instrument to touch the frogs, the absence of such a reaction. Galvani believed that this phenomenon occurs because the body of the animal a sort of internal generation of electricity, which he called “biopower”.

 

Galvani’s discovery aroused great interest to physicists who contributed to repeat the experiment of Galvani, an attempt to find a way to generate electricity. The volt Italian physicist (Alessandro Volta) several times after the experiment are: Galvani “biological electricity” is not correct, the frog muscle was able to produce current, probably a kind of fluid in the muscle car effect.

 

To demonstrate their point of view, the voltage at two different types of metal immersed in a variety of test solution. The results showed that the film of two metals, as there is a place with the solution of the chemical reaction between the metal can generate electricity.

 

1799 volts in a zinc plate and silver plate immersed in salt water was found to connect two metal son have accounts through. He therefore asked a number of zinc and silver film between the pads of cloth or paper soaked in salt water dishes stacked together, hand-to-end, he feels a strong current stimulus. Volts using this method successfully in the world’s first Dell Latitude D620 battery“heap of volts of electricity.” This “V Battery” is actually a series of batteries.

 

In fact, while there are two kinds of metals immersed in a solution, it may produce galvanic action. Had received surgery metal fragments found friends, with the tongue licking the metal fittings, you will feel “Ma Ma” feeling, because a variety of metals used in the lining had a battery.

 

1836-Brittany Daniel on the V stack “had improved, but better after another battery burner” and “Grove cell” and so escape. However, at the time, regardless of the type of batteries are needed to fill the liquid between two metal plates, handling is very convenient, especially the battery is used in liquid sulfuric acid, in time movement is very dangerous.

 

2 Evolution: From “portable” for reuse

 

The initiator of dry batteries in the age of mid-19th was born. In 1860, Leikelanshi France (Georges Leclanché) invented the carbon zinc batteries, which are easier to manufacture, and the initial wet water-based electrolytes progressive disorder with sticky dough type similarly to replace and, when they are packed in containers, “dry” sexual toshiba PA3191U-3BRS battery took place.

 

Invention Leikelanshi dryland

 

In 1887, the British Hellesen (Wilhelm Hellesen) invented the first dry. Compared to liquid batteries, the battery electrolyte is a paste, will not spill, easy to carry, so access to a wide range of applications.

 

Today, the dry cell has developed into a large family of over 100 different species. Common ordinary zinc - manganese dry batteries, alkaline zinc - manganese dry batteries, magnesium - manganese dry battery and so on, but the first invention, carbon zinc batteries is still the largest production of the modern dry cell. Battery technology continues to evolve in the process, new problems have emerged. It was found that despite the dry easy to use, inexpensive, disposable waste, but can not be reused. In addition, due to the metal as raw material easily lead to waste of raw materials, waste batteries can also cause environmental pollution. As a result, may be repeated charge discharge cycles, the repeated use of the hp Pavilion dv4 battery in a new direction.

 

In fact, the batteries can also be traced to the first invention of 1860. This year, the French plant (Gaston Plante) invented a battery electrode lead. This battery is unique in a period of time where the voltage drop of the battery, you can switch to reverse current, so that the battery voltage is picked up. Because the battery can be charged and can be used repeatedly, so called “battery.”

 

In 1890, Edison invented the iron-nickel rechargeable batteries, rechargeable 1910, commercial production of iron and nickel batteries. Today, more and more types of rechargeable batteries is rich in the form of increasingly diverse, the oldest of lead acid batteries, a battery of lead crystal, the iron-nickel batteries, and that silver zinc batteries, developed for lead-acid batteries, solar cells and lithium batteries, etc.. In the meantime, more and more areas of application of batteries, capacitors increases, the performance more stable pricing more practical.

 

3 Status: New power surge

 

The story can be seen from the foregoing, the entire history of the toshiba PA3284U-1BRS battery can also be considered a “try all kinds of metal can be made batteries” of history. Now the redder metal, industry cell is “Lithium.” Lithium is the lightest of all metals inside, is also lighter than water, especially moving, need to preserve the wax inside. In fact, the original inventor Thomas Edison once had lithium batteries, but due to the chemical properties of lithium metal is very strong, which makes the lithium metal processing, storage, use a very high requirement on the environment, such as along-term lithium batteries have not been implemented. Now people on the drums, “desperate for,” these questions is not a problem. Discharge exactly the weight of lithium batteries energy is high and tension is high, the self is small, can be stored long, so it is during the last 30 years has achieved great development. We use computers, calculators, cameras, watches, batteries are lithium batteries.

 

Li-ion battery that is after the battery voltage at no charge. This battery can be charged, but the cycle performance is not good in the charge-discharge cycle over the formation of lithium dendrites, causing internal short-circuit the BATCL50L battery, under normal circumstances the battery Management is prohibited. Later, Sony invented materials such as carbon anode, lithium-containing compounds to make positive, the charge-discharge process, there is no lithium metal and lithium-ion does, which is lithium-ion battery.

 

The advantages of lithium-ion batteries is very clear: a high voltage, small size, light weight, high energy, no memory effect, no pollution, low self-discharge, the long life cycle, as the most suitable for battery electric vehicles as one. Lithium-ion batteries, lithium-ion electrodes ran between positive and negative charge and discharge. Most cattle in this area of technology is “the structure of cell layers, that is, for many of assault layers very thin and then stacked together, so can be a very small volume of ‘a very high efficiency.

 

To improve ease of use, but the current number of electric cars, lithium can be used ordinary family of voltage-dependent, but the loading time up to several hours. To promote cars lithium battery large scale, the creation of the corresponding fully loaded station is essential. However, in March this year, Japanese researchers have developed a new type of “Lithium - air” batteries free of charge, just replace the water in the cathode-electrolyte function through the area of the map etc. to replace the lithium metal anode can be used continuously. In other words, charging facilities, adding things like a “filling station” rather than a big lock “battery charging station.”

 

In addition to the battery, people now want out of a variety of ways for storing electrical energy of the vehicle, for example, some have thought that with the speed flywheel for energy storage Qikuai. But the flywheel, once broken, it becomes a bomb, I did not Kaopu. Now the main research is to use the battery. In addition to lithium-ion batteries, there is a battery cell is promising “fuel”, which is a way to exist in the fuel and oxidant chemical energy directly into electricity plant. Fuel and air were sent to the fuel cell, electricity was produced well. One of the most convenient is to use hydrogen or hydrogen rich fuel gas containing the fuel cell.

 

The battery was born 200 years and they continue to move forward. Past and present the objectives of the battery has not changed: people everywhere to enjoy the electricity of a big favor.

Planning the development of new energy vehicles

 

According to media development and reform of the Commission motor team leader Wang Shulin, has revealed “new energy program for vehicle development was presented to the Council of State should officially promulgated in March 2010. In addition, State agencies will also be launched next year, development of new energy vehicles for the five accompanying measures. Analysts estimate that the new energy industry of the Laptop battery will most benefit from the concept of new energy vehicles.

 

The new energy vehicles in March next year, introduced the planning or

 

If the concept of energy market news, sauteed, in policy came good constantly. Held recently in Nanchang, the new energy vehicles and lithium-ion batteries feature forums, the National Development and Reform Commission automobile team leader Wang Shu-lin said that China will soon release of new energy vehicles, specifications techniques, and new energy vehicle development presented by Development and Reform Commission of the State Council, was officially promulgated in March next year.

 

CITIC Securities (600.03 miles, Bar Stock) Auto Industry Analyst Cheng believes that this concept of some new businesses IBM ThinkPad X60 battery power, as Shanshangufen (600884, bar stock), Jiangsu Guotai (002091, bar stock), companies production of batteries, etc. to receive more, but for the entire automotive sector in particular, SAIC, FAW and other major car companies have little effect. Energy vehicles would be the automotive industry and its upstream segment of the cell concept of society have an impact. March release, “the restructuring of the auto industry and the revitalization plan” submitted in 2011 to form a production capacity of 500,000 short-term goal, which is currently more than 1300 million units for the production of the automotive industry is concerned, a very small proportion of new energy vehicles. For their own societies smallest battery to the past, mainly the provision of mobile phones, computers and other battery-quarter production traction batteries, 500,000 will be a huge volume of activity, hence the emergence of new energy concepts will greatly enhance the performance of these companies.

 

From March 2009 “published by the restructuring of the automotive industry and the revitalization of planning” in response to vehicles with new energy into the electric car, Development and Reform Commission has been clearly put forward in 2011 to form a production capacity of 500,000 short-term goal. It is understood that electric vehicles, power VGP-BPS10A batteries, electric motors, power electronics, the cost of key components, which represents the cost of electric vehicles by 30% -50%. Based on the calculation of 500,000 electric vehicles with a value of annual production expected to reach 1,000 billion yuan.

 

Previously, the two countries issued a joint statement in Beijing, the two sides agreed during the next five years, Sino-US Joint Research Center of the investment for clean energy at least 150 million U.S. dollars the priority research topics will own cars. The market believes that Sino-US Joint Declaration on cooperation in energy sources such as news, digital, relatively rare in history, new energy vehicles are expected to form a positive plate material.

 

The State Council Development Research Center of Industrial Economics Research Department, Feng Fei energy experts believe that both parties should take the initiative in the field of electric vehicles for cooperation, Xinhua China (600,795, bar stock) in a car walk has a large market and low manufacturing benefit costs, however, the overall level of automotive, industrial technology, the infrastructure was not enough, the United States, it is precisely in this area has a great advantage if both parties take the initiative in the field of electric vehicles to launch a new type of automotive products, will become a reality.

 

Automotive Li-ion batteries to double next year transfers

 

As environment-friendly vehicles worldwide are sought, the hybrid electric cars and sells the coming years, the automotive market lithium will develop rapidly. Fuji Institute of Economic Research said that from the 2010 car market lithium batteries will quickly recover and continue to grow. The report predicts that by 2014, manufacturers of batteries that the overall amount of total shipments in 2008 increased by 45.2% to 6.2392 billion yen. Among them, rechargeable hp Pavilion dv4 battery market will be extended to 4.9983 billion yen, an increase of 66.8%. It should be noted that the needs of the automotive industry will become the main engine of expansion of the battery market is expected in 2009 shipments of lithium batteries automotive sector will amount to ¥ 10,400,000,000 in 2008, based on double ¥ 25000000000; In 2014, the market size will expand rapidly to 2.25 billion yen, or about 215 times in 2008.

 

Management Consulting International firm Roland Berger Strategy on the global outlook for new energy vehicles in the last research report predicts that by parts of the electric power in 2020, China is the drive assembly and components market worth 10 billion euros Chao, whose 2011, 2014 and 2017 the market value of 600 million euros, respectively, 2.4 billion and 56 billion euros, the estimated market value of the environment in 2020 will reach 6.5 billion euros, even a conservative estimate will reach 2.4 billion euros. According to forecasts the next 10 years, Chinese enterprises in the hybrid and electric vehicles future developments in the field have an advantage, in particular, the basic components, including developments in the field of toshiba PA3191U-3BRS battery has a great potential because Chinese companies have the advantage of cost of raw materials, manufacturing equipment and labor cost advantage.

 

According to Roland Berger predicts that 2020 will be the main markets in Western Europe, electric vehicles and plug-in hybrids will be more than 3 million in annual sales, China ranked second to reach 1.58 million of units.

 

With the plug-in hybrid electric vehicles of all relevant factors, the Roland Berger predicts that by 2020, elements of the battery of the global market share in the largest share of the market size of EUR 9,600,000,000 — 297 between. Now that the Chinese suppliers and Japan, South Korea, North America, Europe, the supplier has a significant cost advantage compared to, the future of the standard battery of quality, durability and differences prices will become increasingly small.

 

Roland Berger estimates that the demand for battery electric vehicles will be the future of lithium the main source of output growth is expected for 2020, there will be eye-catching 70% of average annual compound rate of growth. Despite the significant growth in demand, but because of higher reserves, experts do not believe that the production of lithium will be a shortage, but there may be a price increase in the risk of a temporary existence.

 

Promising varieties of independent innovation of automotive batteries

 

Shenyin analyst Wang said that under optimistic about new energy policies to promote investment opportunities in the automotive battery industry, promising varieties of independent innovation of automotive batteries. Shenyin the next 3-5 years, Ni-MH batteries, HEVs will remain the mainstream of new energy vehicles, HEVs will PH EV, EV co-existence about 10 years. In 3-5 years later, with iron to increase the performance of lithium phosphate to lower costs, and the national network of charging stations in place progressive lithium iron phosphate as the main engine PH of the EV, EV mark the beginning of a broad development prospects. Recommended Section Li Yuan (600,478, bar stock), Shanshangufen, Jiangsu Guotai, Tibet Mining (000762, shares bar).

 

Shenyin should grant political future, and the rate of localization is likely to hook. In the development strategy, pending the countries new energy vehicles as an opportunity to catch up from behind their own technology. I believe Sino-US cooperation, China will continue to insist on independent R & D path. Possible future introduction of new energy standards car allowance, spare parts and the main rate of localization will be linked to, and encourage the autonomy of key parts as soon as possible and depending on the location of raw materials. At the same time the state will improve the access threshold, and rigorous review system products.

 

Shenyin should follow the state ministries and commissions, will be introduced to encourage large-scale electrical vehicles and the development of specific incentive policies. The industrialization of new energy vehicles, including the most important policy for consumers to buy new energy vehicles are subsidized, and the development of new VGP-BPS10A/B energy vehicles and infrastructure planning. The introduction of these two policies that will address bottlenecks in the consumption and use of the bottleneck.

Battery power supply design is the development of chemicals and the workers of scientific research, technical staff, knowledge and skills.

 

1. Battery Design Basis

 

• The design goals of battery and the basic principles of

 

Cell is the design of instruments and equipment to provide the best use of the performance of work or power outlet. Therefore, the design of the Laptop battery must first be used to meet the electrical requirements and optimize it with the best overall performance, to determine the battery electrode, electrolyte membrane, Shell and other parties parameters, and they are hand are made to specifications and indicators of battery or batteries.  

  

• design of the battery requirements

 

Battery is designed to meet the object (or user equipment) made the request. Therefore, when designing the battery, the first to have a detailed understanding of the items on the performance indicators of the battery conditions and user requirements, generally include the following:

 

• the battery voltage;

• Battery operating current is the normal current and peak current;

• Battery working hours, including time to discharge continues, the use of the term or life cycle;

• Battery work environment, including hours of work in which the Dell Latitude D510 battery status and temperature;

• The maximum size of the battery.

 

Should also be taken into consideration: the source material; battery performance, characteristics of the battery of the determinants of battery technology, economic indicators, environmental issues and other factors.

 

• performance assessment battery of key indicators

 

Battery performance in general, mainly the following aspects to evaluate.

 

(1) The capacity of the battery capacity is defined as a rejection of certain conditions, can be obtained from the battery power, which is currently on full time, generally expressed in Ah or mAh, this which directly affects the maximum operating current of the hp Pavilion dv4 battery and working hours.

 

(2) The discharge characteristics and internal resistance characteristics of battery discharge is granted the discharge of the battery in a system, the fineness of its operating voltage, the voltage level of the platform and the performance mainstream discharge, etc., which indicates that the battery with a capacity load. Battery internal resistance including the ohmic resistance and polarization resistance electrochemical discharge current large, the resistance of the flow characteristics are particularly evident.

 

(3) Operating temperature with electrical work environment and conditions require the use of batteries in a specific temperature range with good performance.

 

(4) The storage performance of the storage sony VGP-BPS5 battery for a while because of certain factors for changes in performance, causing the battery to discharge, leakage of electrolyte, the battery short-circuit and so on.

 

(5) life cycle (secondary battery) life cycle means the system of secondary batteries in accordance with a certain load and discharge its functions reduced to a certain level (for example, the initial capacity of 60% ) when the number of cycles.

 

(6) The internal pressure and resistance performance overload (secondary battery) for Ni-Cd, Ni-MH battery and other sealed type secondary, high current for recharging the battery internal pressure can reach the balance and equilibrium pressure of the high and low resistance of the battery current level of overcharging to measure the performance of performance are all important indicators of good or bad, if the battery internal pressure reaches the equilibrium or balance, the pressure is too high, it will limit the devices battery voltage (such as explosions bullet proof) to open the battery caused by discouragement or neglect fluid, which leads rapidly to the failure of the battery. If the device fails, pressure limiting, there may cause cracking of the tank apple iBook G4 14 inch battery or an explosion.

 

2. Battery design the basic steps

 

Battery design staff in design tasks clearly and fully prepared, you can imagine.

 

User requirements depending on battery design ideas from the battery, there are two: one for electrical equipment and instruments, rated capacity of the power source, and another is just one factor given power supply form developed excellent battery performance specifications for new or special-shaped battery.

 

1 to determine the ability of design steps of the battery

 

• determine the number of combined organ cells Tenor battery voltage of single battery and current density.

• According to user requirements to determine the overall work of the battery voltage, current indicators of operating and other series of selected cells, the light of the series “Volt-Ampere curve “(derived from empirical data or experience) to determine the work voltage of single cell and current density.

• determine the number of batteries in a single cell.

= The number of total voltage single battery voltage / battery

• Calculation of battery capacity

• According to the requirements of course work and working time calculations of charge.

Nominal Capacity * = current operating hours

• determine the design capacity of

Design capacity = capacity * Design factor

A design factor is to ensure the reliability and lifetime of the whole of the battery, the general attitude 1.1-1.2
