Digital battery

Many people now in the hands of products increasingly electronic. But you do not realize that almost all these electronic gadgets are to rely on battery-driven. All these batteries after the expiration of their useful life should be eliminated, which means that the disposal of VGP-BPS13A/B VGP-BPS13B/B batteries is used more and more serious. If the batteries are not handled correctly with the garbage daily in municipal landfills regular releases of heavy metals and chemical solutions are most likely to cause environmental pollution, and even reduce pollution of water. So in the end what kind of batteries should be recycled?

 

1. What type of batteries should be recycled?

What type of batteries should be recycled, according to the battery if it contains an element of substances harmful to the environment? In other words, whenever the battery contained inside: lead, cadmium, mercury, silver oxide and other toxic metals, or active elements such as lithium, should be required of ‘make recycling.

 

Lead acid batteries (lead acid): they must be recovered. Used cars, boats, electric bikes, electric vehicles and lawn mowers and so on. Lead acid battery components, plastic shell and the solutions are easy to retrieve. Lead-acid recycling technology is mature cell, lead auto-recovery current of high-acid batteries, but there are also reports of the battery industry such as recycling of fishing is still a vacuum at ‘direct disposal of used batteries into the sea causing serious pollution.

“No” to mercury alkaline disposable batteries (alkaline): We often use the majority of disposable batteries fall into this category. Are now mostly available in the market for mercury-free or low mercury content in alkaline batteries. If the sale of disposable batteries, “Mercury” logo, these batteries are not toxic itself, the basic principle, you can be a general waste abandoned, it will not cause pollution of the environment in particular. But the alkaline battery itself as the steel / zinc and other precious metals, we must encourage recycling.

 

Rechargeable batteries (Ni-Cd, Ni-MH): they must be recovered. It is now available in nickel - cadmium (Ni-Cd), Nickel Metal Hydride (NiMH) two kinds. Cadmium is very harmful to human health, while recovering nickel from high value. Logo general rechargeable battery recycling potential exists. (See immediately if your logo recycling rechargeable batteries and the type of rechargeable battery bar!)

 

Coin: it must be recovered. In addition to lithium-ion button cell, different types of button cells containing a variety of heavy metals, the volume is low, but the toxicity may be large. PB992A PB994A

 

Li-ion battery (Li-ion): they must be recovered. Are our mobile phone, MP3/MP4, and many other electronic products that can be used repeatedly with rechargeable batteries, and now very common. Lithium is a metal very active, easy to heat or explosion, combustion, and much high-value metal recycling is technically easy.

 

Yes, at this stage, a battery recycling rule is:

Rechargeable batteries and button batteries should be mandatory recycling, while the mercury-free single-use alkaline batteries should also encourage recycling.

2. Code of practice for the recovery of batteries

1. Before buying a new battery to determine if they had not run out of batteries;

 

2. If you often use the dry batteries, consider buying rechargeable batteries, rechargeable batteries, but should remember that recovery; PA3399U-1BRS PA3399U-2BAS

 

3. Save the batteries used, should ensure that the battery fully discharge and stored in a dry black, are not stored in airtight containers in the air (because the batteries can release hydrogen and lithium batteries easy to heat or spontaneous explosion);

 

4. Pay attention to neighborhood stores convenience / supermarket / malls or district container recycling batteries to the battery input accumulation of waste;

 

5. If you have not found the time being near the recycling boxes of batteries, you must find where the city, no recycling of batteries, if not, then try to save the batteries scrap.

 

Abstract:

Recall of batteries for which he is a very real problem, many people accumulate a certain number of batteries, but do not know where to recovery. In other countries, many supermarkets have recycling companies are placed in recycling bins for batteries or recycling bins by the battery manufacturer. In the living quarters inside, the waste separation and recovery is also a dedicated facility to recycle batteries. But in China, first, recycling bins battery driver that is not used effectively, it was often “enough food” (the recent reports of 2: 1, 2,), on the other hand, the public complained that the recycling of batteries disposed of anywhere I do not know where the treatment given (it seems that only a relatively positive Wuhan relevant reports). Recommendation: The batteries must be left to a dedicated battery recycling collection boxes, and without knowing where the collection points for batteries must be used to save the batteries. Personally, I think that there is no system of waste separation and recovery situation, d ‘require all omnipresent convenience stores / recycling boxes supermarket placement of the battery, and certainly with the recovery of eye-catching logo, which is to facilitate the general public may be the most effective method of recycling batteries. LCBTP03003  Aspire 3000 battery

Toshiba has been engaged in developing portable fuel batteries, although in a few months before the products of trial exposure open, but they have still not been put into production. Not long ago, Toshiba has finally made the decision to the fuel PA3383U-1BRS battery market. Stacks of security as the most important uses a large quantity of stainless steel and aluminum and other metal parts. This document will include fuel batteries and development of portable products, technical advice, analysis of new products.

 

“People see a single list itself” (portable personal technology products). Toshiba by the end of October 2009 announcement of the 3000 limited edition battery phones fuel “Dynario. Crisis on the market for fuel battery, phones and staff the fuel battery technology are issued with wonder and gratitude for the vote.

 

After the introduction of the battery, a number of developers of fuel batteries immediately resumed multi-block and carry out audit work. Words such as “From the entrance of moisture is constant and smell the methanol fuel and so on, can feel a high degree of completion of the battery,” “Even if only the measuring the temperature of bath water, but heat is still a cause for concern, “and so on, all kinds of reactions are very rapid after another. We also bought a PA3395U-1BRS battery newly listed fuel and to analyze characteristic. And Toshiba, with help from the public an internal component.

 

In fact, more than 30,000 yen?

 

Dynario is a fuel battery direct methanol (DMFC). Able to use the terminal as a portable USB charger. With the built-in lithium-ion rechargeable battery set, the maximum power of 2W (5V, 400mA). The batteries can be injected in 14ml of methanol. Use of fuel “may be portable so full of 2″ (Toshiba). We use 1W power consumption of LED lights to confirm the results show that sustainable power generation to 11 hours or so, one in the new generation can be estimated at about 11Wh.

 

Fuel battery from Toshiba can be recharged via USB for portable products. The fuel use of 50 mL bottle filled with fuel. Dynario sells ¥ 29,800 including tax. As a battery charger external point of view, the price dearly. Toshiba said that “the price is higher because the specialized multi-component system leads to the high costs, while the actual removal process, it is surprising to many parts was beyond the imagination (Figure 2). This is due to the PA3399U-1BAS battery by adding a large number of ultra-small pumps and valves, MCU (microcontroller) and IC control, control of speech and if the circuit Outside the components of fuel batteries. In addition, starting on the outside metal and reinforcement of the shell composition is also too high. Most Portable and industrial fuel batteries, the developer, said: “Given the account component and manufacturing costs, ¥ 30,000 is really not enough.” There are two units of energy, fit two sides. In addition to generating part of the NMR systems, generation of control components and parts used to ensure robustness as much attention.

 

Fuel cock laboriously

 

Dynario the basic elements - both inside and outside the central part of the shell to configure a unit of electricity. In addition, the center speaker is also equipped with Sanyo Electric produces cylinder-type lithium ion rechargeable batteries and two to install the power switch and input terminals and output to control floor. The fuel tanks are deployed in the central reservoir side of the surface of the battery and back with aluminum (Al) alloy casing, the upper and lower exterior of the resin. “As one of the first volume of products, they attach great importance to the longevity and strength, a large number of metal parts used (PA3399U-1BRS battery industry Fuel). Power production unit is placed in the grid electricity type plate and stainless steel plate as a fuel tank between the resin. Stainless steel plate with the fuel is the result of rivets fixed so I can break no, you can not remove the plant. Lattice-shaped stainless steel plate next to an entry device for generating electricity, fuel supply side of the board set up power generation and supply Fuel control the fuel pump ground fuel valve. Control floor installed on the fuel pump and fuel control valves, and 8bit MCU and other IC.

 

Generating unit installed on pumps and fuel valves and other components with the corresponding control IC. Most IC is designed for the development of fuel batteries.

 

Generation unit is equipped with eye-catching is that the fuel valve and fuel pump (Figure 4). Since both mechanical drive, making it more energy efficient, ensuring sustainability issues. In addition, the portable fuel PA3399U-2BAS battery requirements for the smallest and thinnest high, so according to conventional wisdom, this part is the penalty “(personal fuel battery technology). Methanol from the fuel tank in plate fuel, the use of pumps to supply the entire MEA (a). The amount of methanol injection tank of fuel can be used to adjust the fuel valve (b). Vibrating piezoelectric element can change the pump pressure, injection / discharge of fuel (c).

  

Toshiba, the design of the fuel valve also takes great care. In comparison with other components, valve projecting fuel approximately 6mm. Compared to the fuel pump and control the installation of floor and other parts of the whole thin, it seems that only the fuel valve may not have time to develop products with low profile. Therefore, the position of the fuel distributor installation with the Center are also shifted by two power units contrast adjustment, while the reduced thickness of the battery. Power production unit consists of four devices into a single chip set consisting of the MEA. MEA area of approximately 40cm2. As there are two units of energy, so the output density is estimated at around 25mW/cm2.

 

In addition, the fuel pump using the PA3399U-2BRS products Murata Manufacturing. His use of a piezoelectric element, thin size to 24mm × 33mm × 1.325mm. Output rate 0.001mL / s, discharge pressure of 35kPa. To supply fuel for power generation and methanol through the fuel valve and the first supply of fuel entering the injection plate. Then, with the fuel pump to make two small holes in the center plate diffuses across the device.

 

The density of production of about 25mW/cm2

 

Power production unit from the outer dimension of 81mm × 52mm MEA (membrane electrode composite body) and body composition collector. MEA unit using four 81mm x 9mm. Think that the unity of the electromotive force of each piece is approximately 0.3 V, 1 Ge voltage generated by the power units to just over 1V. After generating unit control with step-up circuit on the raised floor to 5V or so. Pro forma density unit of output, only about 25mW/cm2. It was also suggested that “the problem may be heat-density limit output to such a degree “(a personal fuel battery technology). Regarding the solid polymer membrane, called” now under development are two types of fluorinated hydrocarbons and (Toshiba), this product is used which is unclear. But the majority opinion that “the possibility of greater use of fluoride” (a number of staff to fuel battery technology).

 

The direct use of experimental floor

 

Is located in the lower part of the power switch the PA3421U-1BRS battery terminals and input and output have been installed in the control on the floor. Dynario equipped with lithium-ion rechargeable battery. Its role is to control circuits for the units of electricity to power and the unit production of electricity from the start-up power smoothly before the burden of supplying electricity. Power switch part and the part of the control input and output separate floor. Backplane with two connectors connected. Power switch on the bottom to receive electric power generation interface unit (a). Backplane on the input terminals and output are connected lithium-ion rechargeable battery interface (b). Control of Lithium-ion rechargeable batteries and units of electricity seems to be controlling the power switch integrated flash on the floor 8bit MCU. The MCU can be rewritten, a large number of test pads on the chassis of speculation, including the control unit of power, including low, the product may be directly followed the experimental floor (fuel Staff batteryular technology).

 

In addition, the power switch on the bottom also installed 2 Mbit / s flash memory is considered to be used to save time loading and temperature changes. Lithium-ion rechargeable battery and control input connections and output terminals of motherboards for the bottom to provide a driver circuit units of electricity. As Dynario is the first volume of portable fuel batteries, Toshiba strongly under the law to ensure safety. As he had when the battery stop working automatically when the temperature rise function. For this purpose in entering the power generation unit is equipped with a temperature sensor to monitor the surface temperature, so it does not exceed a certain interval. Our tests confirm that when the surface temperature reaches about 45 ℃, the battery will automatically stop working.

 

In addition, the company said in response to temperatures above 100 ℃, the battery is also equipped with temperature starting capabilities and cons screen input terminals and output in the high current function.

 

Fuel Bottle also pays attention to safety

 

Dynario now need to use 50 ml vial filled with fuel for fuel. Fuel bottle with Toyo Seikan, develop, and the PA3534U-1BRS battery, as security have not been lax. Bottle with a double structure, in line with the IEC (International Electrotechnical Commission) safety standard (interim standard). “Even with 100 kg of withstanding the impact will not be damaged” (Toshiba). In addition, the company said, in exceptional form Pingzui and the role of internal agency, as long as the stack of fuel injection in the entrance channel which is not correct, the fuel does s’ sells it.

Portable using a period of time longer prone to the problem of declining capacity of the battery, leading to the life of the battery cell shortened. This is essentially internal batteries or battery failure caused by aging. In severe cases, the use of calibration procedures of the Laptop battery or the battery charge and discharge are repeated to solve the problem. For this issue, there are many fans that the shell of the battery opens, find and replace the batteries may be unable to solve the problem. The current situation is really the case?

Replacement batteries must be cautious

 

Since the laptop is now a greater use of lithium-ion batteries, while the life of lithium-ion battery is essentially constant, and its battery life of only 500 to 800 times. Therefore, if often use battery-powered laptop, later, 1 ~ 2 years, the battery is easy to achieve because of the internal life of the batteries fail. As we open the battery when the battery test is represented in one or two batteries damaged. However, due to other cells that is about it, even if you replace the batteries fail, the battery can be quickly returned to normal, will soon fail for other batteries and battery life can be full used again.

 

Then, all of the laptop Dell Latitude D820 battery to replace all the internal capacity to solve the problem? In fact, it’s hard. Because in the original cell, after its internal batteries game specifically, if the battery capacity, the terminal voltage and internal resistance of the consistency property. We bought on the market in batteries, and have not been tested and matching, we can not for the amateur conditions, combined batteries, so its capacity, internal resistance and other parameters vary inevitable. In the internal battery, batteries are in series between them after the load (in most notebook battery, is 8 cells were divided into two groups, four in series and then parallel to form a battery pack) due to the battery charging current from which the smaller capacity batteries will be the first total power, but not enough because the other battery, the battery terminal voltage can not create voltage load circuit will continue to charge the battery pack. In this way, the batteries supply the original track will be overloaded. To reduce the charge time, laptop charging circuit load current is very high, so will charge batteries when the tremendous heat, so that the batteries inside the liquid temperature increases, pressure increased, the internal electrolyte easily dry up or overflow, leading to a further decline in cell capacity, there is a swelling or even an explosion. The total capacity of the battery capacity by the decisions that smaller batteries, so that would create a vicious circle, after repeated charge-discharge capacity of the whole battery would be considerably reduced, which leads the ‘Time use laptop.

 

At the same time, a number of laptop batteries to prevent unauthorized users from opening to replace the batteries, has a microchip and an anti-line off Cape. As the hull of the hp 417066-001 battery or batteries to open the line of the battery Remove the card and smart circuit protection will cease production of the battery. Even if we re-take the battery circuit of the battery and close the battery chamber, its smart protection is still not recovering. In this way, the battery will not work out. We need to re-reset the smart chip to solve this problem, but a condition amateur can not reset the chip to chip. Therefore, replace the batteries when the battery can cause permanent damage.

 

So how can we solve the battery problem? The best way of course, is to buy a new battery of origin, but now a new original equipment batteries for hundreds or even thousands of dollars, this cost is too high, higher than many consumers can afford. However, there are a number of professional station laptops repair, equipment and technology are good, but there are repair stations and manufacturers of batteries existence of long-term cooperative relations, the VGP-BPS8 battery can be made corresponding precision. This would maintain the quality. In these places for the price of batteries is about 300 yuan, although it compares to replace the batteries of their own at higher prices, but it can protect the long-term use of the battery. In addition, some service stations are also carried out repairs for six months before the battery warranty. We use these six months, while there are a hundred times or two to ensure the battery charge and discharge, and battery capacity and stability during this period, then after the battery is about to enter a stable period is not easily damaged.

 

The trick to keep the battery

 

In any case, replace the batteries do not require us to pay a little more, so we must be aware in their daily use to maintain the battery to extend battery life. To protect the battery, first reduce the number of battery, which means it is electricity to the extent possible not to use the toshiba PA3399U-2BAS battery. This can reduce the number of loading and unloading of the battery to extend battery life. Although this use to a few drawbacks, but think of you each time you use the battery, it must pay two dollars, be prudent in the summer bar.

 

Battery internal structure diagram

 

Calibration procedures battery can extend the battery life has been a debated issue. Support of people think that the calibration of the battery can eliminate the memory effect of batteries to extend battery life. Opponents argued that now use lithium-ion batteries have no memory effect, if the correction procedures will only increase the number of loading and unloading of the battery and shorten the life of battery. In fact, two types of agreement are incomplete. While the reduced lithium-ion battery memory effect, but the memory effect still exists. Calibrating the battery may actually reduce the memory effect, but this is not the most important function of calibrating the battery main procedure is to establish the battery and control circuit, in order to optimize the control circuit can correctly identify the capacity of the battery to avoid overcharging or over-rejection phenomenon. At the same time, you can also ensure that the apple A1079 battery is exhausted before the system closed to protect data security. However, frequent use of calibration procedures of the battery would indeed increase the battery charge and discharge time. Therefore, we once every three months or if the calibration procedure of the drums on it. We use energy from the battery when the laptop or adapter to charge the battery, disconnect the battery cell. Regardless of the battery is charged or discharged state, the current is very important if we try to connect the battery, it is easy to produce electrical sparks, not only will the removal of contact, the impact of the current May also cause the board of the battery or system portable charging circuit damage.

In addition, many people there are some misconceptions about the use of the battery. Such as “newly purchased batteries need to go through a few charge-discharges to enable,” “laptop battery needs to full output:” In fact, Li-ion battery memory effect with the reduction and improving battery protection circuit internally. These factors affect the capacity of the battery was very low, and we only run the calibration procedures of battery on a regular basis will be able to eliminate the impact of these Operations on the stack, we must not wait for that, and that more carefully your laptop, after all, the battery is presented useful.
