Digital battery

Influx of a large number of companies, but it is followed by a rapid decline in profit margins, current earnings are relatively modest. “According to one press access to information shows that in a few years, the profits of the sector before 100% of profits fell to 5% of profits are low.

 

Moss is the beginning of

 

“In Shenzhen alone, there are hundreds of production companies, all countries should be more than 1000 of the”. Zhi-Ming Zeng said “China’s Sankei Shimbun reporter, although the development of the industry supply lithium just a few years, but the pace of development beyond imagination.

 

Zhi-Ming Zeng worked in Beijing, Anwar Ibrahim on United Energy Technology Co., Ltd., has been witness to this emerging industry since its Laptop battery birth, then quickly dissolved into chaos after the development of the whole process.

 

Beijing Anwar United Energy Technology Co., Ltd in the industry is also a relatively big businesses and claimed to be the best technology for domestic iron phosphate factories producing batteries, the main development, manufacture and marketing of new batteries power rechargeable lithium iron, lithium-ion rechargeable battery and its subsidiary products are widely used in electric vehicles (EB / EV / HEV / PHEV), electric tools, solar, UPS, digital products, products of export to Europe and North America.

 

 

Currently, however, Beijing Hualian contract security industry, like the vast majority of companies is in the common development of the industry to feel the pain of confusion.

 

If Sony in 1992, the company will sell lithium batteries as a starting point for the dates industry. Then, set up by thousands of businesses, there is a sizeable proportion of companies are neck and only 50 million fund has committed more than 10 employees, renting office space, and even BTP-43D1 some minimum level of production equipment has not yet completed its acquisition of haste.

 

“These companies are not standardized operations, directly leads to lower margins on products, currently only a small number of large enterprise customers end because of stability and healthy development.” Zeng Zhi-Ming laments.

 

“2007 years ago, few people realize that the lithium iron phosphate promising, but production of lithium iron phosphate over 100 companies.” Xu Gang, vice-president of Tianjin power of God in the media about the fierce competition in the sector said. “The real business is doing quite well very soon.”

 

Technology Highway

 

According to the industrial chain, the lithium in batteries and produces batteries, Dell Latitude X1 battery materials can be divided into cathode materials, anode materials, membranes and electrolytes. Lithium cobalt oxide, manganese oxide, lithium nickel cobalt manganese-lithium and lithium iron phosphate cathode material for Li-Ion battery technology, the basic material Zeyi graphite anode, solid particles of carbon-based; in positive and negative electrolyte East and diaphragm.

 

The status quo is both manufacturers of lithium battery materials and battery manufacturer, has technical advantages of firms are very small.

 

“The main problem the industry is not competitive and disorder problems, the most critical issue is the price and technology.” Institutional research Frost & Sullivan focused on energy sector analyst Linda again told ” China’s Sankei Shimbun “Report to the United States, Japan and other countries, the Chinese Li-ion hp Pavilion dv4 battery industry, the technology gap is evident.

 

It is understood that companies worldwide have also strengthened their research and application of lithium batteries, but lithium batteries and other current high explosive which remain outstanding and Chinese manufacturers in the most backward in this regard.

 

BYD is a relatively rapid development of industry and enterprises in technology also have the advantage over their peers. BYD propaganda techniques, but actually did not get all the benefits of peer recognition, Zhi-Ming Zeng on BYD lithium battery that is not new, and the United States similar to products similar.

 

Li-ion battery industry has been concerned about the development of wind investment industry, Chen Qiudong also noted the technical level of the industry problem of the poor.

 

Chenqiu Dong said the domestic iron phosphate lithium material is not a company analysis, each doing a half-dozen properties of materials are needed for the overall level is not difficult, but to do this material (in particular, is to watch the processing performance, stability, and discharge broadband sexual characteristics) is not easy.

 

Statistics show that China, Tianjin, Shandong, Zhejiang, China (Jiaxing, Huzhou, Jinhua) and other places enormous investment of many to the sony VGP-BPS2 battery manufacturer Li-ion batteries, the results will die of ‘a natural death, the main technical issues can be resolved. Chenqiu Dong said that with technology partners to find a great association. Many colleges and universities or research institutes, technology is just technology laboratory, far from industrial. Laboratories doing material properties are excellent, but the pilot will encounter great difficulty, even if reluctantly passed the test pass, the stage of mass production industrial, exposing the problem will be even greater . And this is not an isolated phenomenon, but rather a common phenomenon.

 

Linda noted that in addition to technology, the price of lithium high power hamper its rapid implementation is a key factor.

 

For example, a lithium-ion battery electric bike for the price of 1,500 yuan, while the current total price is also an electric bike, but about 2,000 yuan, if electric cars are being lead to the most-assembly acid batteries.

 

“The main reason is the high cost of production is low, there is no scale. If we can balance the production, sale, these costs should be quickly abandoned.”

 

Achieve the same high prices of the deepest reason is still an immature technology, resulting in the production and marketing limits.

 

CITIC Guoan (15.44, 0.25, 1.65%) Mengguli Power Supply Technology Co., Ltd. in Beijing during the Olympics for the 50 pure electric buses in operation provides the necessary batteries, and its technology in the industry considered relatively mature, and even well, its Lu, general manager of its admitted, “synthesis technology of lithium is still a problem.” The stability, consistency of production and life of the technology of lithium batteries is not yet mature.

 

Warlords battle for the throne

 

Warlords battle for the throne, such companies will win?

 

In short, technology is king.

 

On the most critical factor in business development, Zhi-Ming Zeng said the two words “innovation”. He was referring to technological innovation.

 

Linda noted that the company will finally, it must be to solve the problem of toshiba PA3191U-4BRS battery price and technical aspects of the business.

 

Technology, Chen Qiudong consider more comprehensive, he summarized the following three elements: mature technology, a strong management team and excellent resources.

 

Chenqiu Dong said that the three are complementary, we can not do without. There are no mature technology inevitably limit the speed of development, so stay in laboratory techniques, or at least have been at least 2-3 years of exploration, technology and talent are also inseparable After all, the lithium iron phosphate material technology and is not fully mature, the industry has no uniform standard, equipment, materials, processes, and so the real questions should be able to count on people to solve. Without a strong financial strength, even if the materials out of, the corresponding production or management can not keep, they lose opportunities for collaboration with key customers, key technical staff for motivating the team enough, lead loss of human resources. Have no outstanding management team, even the best technology does not produce value here includes the implementation of the said R & D, production management, quality management, marketing and other links for startup companies that are very difficult.

 

However, the company won the healthy development of the apple A1061 battery industry as a whole can not be separated. As CITIC Guoan Mengguli Power Supply Technology Co., Ltd., General Manager of the Lu said: “I am most concerned about is when they can regulate this industry together.”

Thirdly, key initiatives aimed at solving environmental problems is the full implementation of the policy of recycling batteries

 

China is actively pursuing the circular economy, waste batteries can be recycled to 90%, but the industrial policy of China does not waste battery recycling a good development space, resulted in their becoming long-term problem bottleneck in the development of China Battery. China is not a lead-acid battery management of waste recycling, legal standards, the country was not prepared to conduct business waste professionals acid battery recycling, not a business or professional secondary battery recycling lead companies to establish a national network and a network of regional collection, recovery of all the work is the decentralized management state of unrest, the recovery rate of waste lead-acid batteries n ‘ is not high. Problems recovery of lead in non-standard commercial rehabilitation and strengthening of management is imperative, the state departments concerned should the policy as soon as possible, as the ban small coal mines, small smelt, as after a waste recycling lead small businesses. At the same time put in place policies to encourage and support large-scale manufacturers of Dell Inspiron 5150 battery recycling used batteries. Limiting the development of secondary industry to lead China are main factors: first, the cost burden of environmental protection equipment. Companies with advanced technology, the protection of the environment and well equipped to benefit the company not modify the technological backwardness of the serious pollution of the city “lead smelting small.” Second, surveillance is not enough. None business license is also under secondary lead production, correction palliative, were closed for “low melting lead, the wind is over, the resurgence. Thirdly, industrial policy is not conducive to business informal. Tax too heavy also undermined an advance regenerated large enterprises to increase the capacity of environmental governance. 

 

Fourth, the development trend of China’s lead-acid battery industry

 

Discharge is more than one hundred years old lead-acid batteries due to low cost materials, simple technology, the technology is mature, self is low, maintenance free characteristics of needs in the decades to come, still dominant in the market although the starter used, the power market space battery in May will be a turning point in the near future the development of domestic industry will remain dominant in the medium term will also be a place in the long term without is necessary to use high weight ratio of energy continue to exist. Currently, its major application areas of origin such as motorcycle motor, power supply parts, etc. in the substantial growth, but also in new application areas such as electric bicycles, buses can be used such as the development of valve-regulated development of hp Pavilion DV1000 battery technology to meet the high technology, such as UPS, power and communications equipment, food needs. As the lead acid battery technology continues to advance, making the electric bike industry, tremendous development, and to fuel cars and fuel to reduce pollution from motorcycles to make a contribution. Maintenance free technique, drawing technology in the grid net for the rapid development of the automotive industry. We can say in these applications in lead-acid battery technology advances to improve the competitiveness of the country has made real contributions.

 

Power tools, electric bicycles and other industries demand for small mobile battery industry has spurred the rapid growth momentum. Electric bicycle battery set most VRLA batteries after a performance improvement, energy and life cycle of a breakthrough, but so far remain in the high flow rate that energy is not quite high, deep-cycle life is not long enough gap largely affected the rapid growth of the electric bicycle industry.

 

Electric bicycle as a means of transport in less developed countries in recent years, rapid development, particularly in China. From 2000 to 290,000 in 2005 developing 12.09 million, the rate of average annual growth of 174%. It is expected that in the future for a long period of time, the batteries of electric bikes products will flourish. China’s Electric Power batteries bicycles used lead-acid batteries for more than 95%. 2006 Electric Bicycle sony VGP-BPS2 battery capacity of 40 to 50 billion by 2015, the output of electric vehicles in China will reach 1,000 billion yuan, including 16.0 billion supporting cells. The secondary market to replace the battery 480 billion, which is a huge market.

 

5, lead to China industrial battery acid, the direction of development envisaged

 

⑴ encourage bigger and stronger, improving the degree of industry concentration

 

To upgrade industry clustering effect, actively respond to various market risks, with equipment, manpower, technology, and effective integration, reduce waste, training of the optimization structural product additional columns for increased investment in efforts to protect the environment, an effective solution to pollution problems in the production process and further strengthen the leading companies in overall strength and realize the magnitude and Development group.

 

⑵ upward trend of lead acid batteries

 

To seize market to expand the size of the lead industry of toshiba PA3421U-1BRS battery acid, and strive for annual production of 2010 of approximately 131.75 million KVAh, sales income of 66 billion yuan.

 

⑶ be development-lead acid batteries

 

Although the lead acid battery technology continues, but the specific power, cycle life and other issues is always the emphasis on industry issues. Therefore, increased efforts in R & D efforts to improve the level of scientific research to enhance competitiveness are the only way for industrial development. Across the bridge and link between the role of the Association, and vigorously for businesses to create a platform for exchange and communication with the upper lead, partitions and other downstream industries, such as vehicles form an electrical and mechanical joint research and development, a group formed to unite foreign ALABC or a similar alliance to jointly research and development and strengthen R & D capability.

 

⑷ accelerate the adjustment of product structure, standardize the market recovery and regeneration

 

Increase the proportion of new products, develop sound and resource efficient products, focusing on the development of sealed maintenance-free lead-acid batteries, the phasing out of open-type batteries. Lead acid batteries to accelerate the technological transformation of enterprises, the use of process equipment for advanced and effective monitoring of the production process problems of environmental pollution, to achieve higher production clean. Encourage colloidal lead-acid batteries, winding type bipolar lead-acid batteries, and other new types of apple A1079 battery research and development, improve the use of more power and lead to regulate the market lead - Recovery of acid batteries and recycling, reducing waste lead-acid batteries of environmental pollution, noise oriented and resource management.

 

⑸ expand, standardize the export market to avoid trade frictions

 

A careful study of the international market demand, the range of export products appropriate adjustments to reduce the export price of competitive products, development of new applications and markets. Occupy the market share of low price, it exports the lead acid BATBL50L6 battery blow to China. At the same time, may be subject to foreign anti-dumping lawsuits, resulting in higher product has been imposed anti-dumping duties, loss of self-rising prices fair. Therefore, the Association should play in regulating the order of foreign trade and industrial development in the role of coordination to protect the legitimate rights and interests of enterprises, establish a standard order of competition to prevent abusive behavior cheap exports. Also studied the relevant policies of the country’s target market to consider establishing manufacturing bases abroad.

Introduced the use of nickel-metal hydride battery of new products also accelerated the acquisition of all the heat, of course, it is unique “temperament” as the energy density, the number of charge cycles and more details ‘memory effect is small, non-toxic metals such as cadmium, mercury are also a number of advantages achievement of nickel-metal hydride Laptop battery position in the bull market.

 

With all the hands in nickel-metal hydride batteries steadily increasing number of scientific leap in the use and maintenance has gradually at the sight of attention. As we all know, the brand Ni-MH IBM ThinkPad R51 battery life can be charged according to the official request that 500-1000 times, but this is actually a good value, and often do not respond to such a life. But as a sensible use of chargers, more in depth understanding of nickel-hydride batteries, metal, we have left to do, “longevity”.

 

1. Under normal circumstances, the new nickel-metal hydride batteries contain a small amount of electricity we buy on driving charge and then reuse. However, if time battery plant is quite short, electricity is sufficient to recommend use first and then reload.

 

2. The new nickel-metal hydride batteries to buy a general charge to go through 3-4 times and use of, performance can play in the best condition, many of my friends for the first time, the prosecution encountered a small problem, for example, the first charge did not imagine the number of PP film so many? In the 3-4 times after charging and the use of all be resolved.

 

3. Although nickel-metal hydride Dell Latitude D820 battery memory effect is small, as much as possible is recommended after each use finished loading and is full of time, do not charge you would use for one count and then. Only longevity, “Oh, the important point.

 

4. The battery charging, the charger should pay attention to the heat surrounding the deliberate use of what wind there too is no need for fans, but noted that the shipper should not put too much debris around. Ordinary users the process of using the battery, the battery is often not a dedicated storage bag; users to replace the battery, will acquire the habit of easy storage battery, regardless of where the place is clean and moist . The consequence is that the battery they get dirty easily, easy-to-metal contact, such as keys, etc. contact, easy to moisture, and it is the enemy of batteries. Recommendation: Users should set up a special cell to place points and keep the battery clean. To avoid problems such as loss of electricity to keep the Dell KD186 battery and contact points of the battery to both ends of the inner lid clean, if necessary, use a soft, clean and dry pasture.

 

5. A long time did not have time, remember to remove the battery from the storage battery, placed under dry conditions recommended brand of battery in the box to prevent short-circuit the battery.

 

6. A long time without nickel-hydride batteries in the metal shop a few months later, the battery naturally in hibernation “state”, the battery life considerably reduced. If Ni-MH battery has been placed for a very long time, I suggest you begin with the slow charge is appropriate to impose. For another important issue at stake here: for Ni-MH HSTNN-LB31 battery, the battery must be completely discharged, then save, store, or online? Both points of view very different from what it should be used? Many people think that we should adopt the first, but I thought that to save the battery charge is reasonable. Because: According to tests, Ni-MH battery to save the best conditions to save about 80% charged. Because the nickel-metal hydride batteries self-discharge rate is high (10% -15% per month or almost), if the battery is completely discharged, then save it for a long time not to use the ‘battery-discharge phenomenon will discharge excessive battery, may damage the battery. Do not believe? So you think to buy a new nickel-metal hydride rechargeable battery is not all there is electricity, which is the reason. Recommendation: Apart from correcting the wrong point of view, maintenance of the battery to start in the right direction, otherwise it will backfire.

 

7. There are many messages from friends post questioned how to meet Ni-MH? After investigation, after many specialists battery reach a unanimous conclusion to remind friends. Do not nickel hydride metal discharge the sony VGP-BPS2 battery, excessive discharge may cause the failure of pricing to harm is much greater than Ni-MH battery memory effect of the battery itself!

 

8. Auto multimeter test battery is full or not. Ni-MH batteries in general charge before the voltage is below 1.2V, filled with normal voltage is 1.4 V or later. We as a judge, also very easy to judge the condition of the battery.

 

9. Chargers can be divided into fast charge and trickle charge. Low load current is small, typically around 200 mA, such as our common load current is about 160mA. His long-time charge, 1800mAh Ni-MH toshiba PA3399U-1BAS battery should be 16 hours or more. Even if I was a little slow, but the charge would be filled very full, and do not hurt the battery. Fast charge current is usually in the more than 400mA, charging time significantly reducing the number of .3 to 4 hours can manage that, but also won the affection of all. Several types of fast charge, prices vary. Therefore, we often have questions about the same load faster, why the price is a big gap in it? Good charger in particular is a good fast charge brought against over-charging protection function, for example, we have a common understanding Acura Panasonic BQ 390 charger has been particularly noteworthy in this regard, excellent software chip capacity charge the battery while it also brought evil upon the battery, quick charger minimized.

 

10. Conflict: trickle charge does not hurt the battery charging time is too long, however; fast charge can save time, but there is damage to the battery, even if the surface is the world need the best degree Panasonic BQ390 charger only very good harm reduction, but not totally avoided. Contradiction can be resolved is to buy a quick charge and a trickle charge. Quick charge with the load for some time, for example, 5.10 times after the transition to slow Chong Chongdian once or twice. This apple A1078 battery performance to return to a higher state.

 

11. The batteries are commonly used battery, four or six, and this time, to maintain the balance of each cell is very important, otherwise, due to a battery problem has affected the work of the entire battery. First, the battery capacity and ensure consistency, the best place to buy the same brand of the same type of battery time. Then the internal battery power to maintain consistency, simply, is that the electric battery is either full or empty. If there are more groups in the composition of the battery, you can try to “select” look. Means that the specific capacity, similar to the battery voltage and other parameters in one set of battery cells in series, due to poor conditions, under normal circumstances let endpoint measures after the tension and son of red blood on it.

 

12. Speaking on the last charge and discharge.

 

Top of the range of NI-MH Aspire 3000 battery charger with battery test delta-V to determine if the battery is full. When the curve of discharge voltage of the battery and is somewhat similar to the beginning of a more rapid rise, followed by rising slowly until the stuffing is good, the tension began to decline rapidly, but decrease in not very large. Before commonly used nickel, cadmium batteries are also similar, but drop the speed and the amplitude was higher than the NI-MH. Most chargers on the market type (less expensive) is often used is the value of the charge pressure, such as the elderly GP 1.4V Rechargeable value Po is the pressure that is precipitated at 1.4V when the battery voltage, because there is no difference, and charge on the end. Such a result is often that the battery can not be bridged, particularly in some older battery due to increased internal resistance, the real addition to the low voltage battery. And this charger currents tend to be smaller, often charging more than 10 hours. Using Delta-V cutoff automatic charger, since it can precisely control the load time, use may be more reliable high-current load. High charging current nickel-metal hydride battery for damage and do not want to imagine the contrary, the use of DC current, but also require high current load. The first is a matter of time, not talk. Then, Ni-MH battery has a characteristic, that is, the higher your current rate, it can release the most common, and now is tigre DC electric current is not small, so relatively speaking the use of relatively large load current is a choice, you can clean the toshiba PA3191U-4BRS battery is added. General 5 charge current should not exceed 1.5 C, C to the battery capacity is 1000MAH batteries, not more than 1.5A. I usually carried with the load 0.5C (my charger with adjustable current). Discharge zone, in normal circumstances, DC Black can be a burden on Na Qu, NI-MH little memory effect. However, in a period of time after use, and the balance of the cell to activate the battery when the battery discharge and control the termination voltage. NI-MH battery termination voltage of 0.9 V, the discharge time careful not to over-discharge, the 0.9V for each battery when it may stop the rejection file. NI-MH battery is not powerful nickel-cadmium batteries, the overcharge and over discharge and is more sensitive to high temperatures. Charge and discharge temperature. In general, do not let the hp F4809A battery temperature exceeds 45 degrees. When the battery is fully charged, the battery will be hot, filled with large current when the temperature is 42 degrees and not more than 45 degrees, otherwise life will soon be reduced, the battery internal resistance will increase. Also, the load of the battery temperature is higher, and so on until after the cooling of its rechargeable battery, charging money for having to wait for the freshness of the battery. After a long time is not re-using, it is preferable to activate the battery to discharge a few times. Usually used in time to pay attention to maintaining the integrity of the wrapping paper, can not be broken in order to prevent short circuits. Do not fight the impact of the battery, do not fire and so on.
