Michigan-the capital of the world's automotive battery industry

Michigan was well-known cities in the world's automotive industry, while the city has now become a symbol of the world economic crisis of the "ghost city." aspire battery Here are everywhere bankrupt auto company and the unemployed, those unemployed are currently looking for a comeback approach. Be able to save the city is the secondary battery secondary battery of environmental protection and use of small-scale automotive industry. Jennifer governor of the region • ancient Ranhao Perm in a recent radio address, said: "I want Michigan to become the capital of the world battery industry."

Countries around the world are promoting a green growth policy, decided to develop into overcoming the economic crisis. Around the secondary battery has launched the initiative in competition between enterprises has become very keen. Meanwhile, the secondary battery control of the domestic stock market has become a new core theme. The securities industry will become the secondary battery is widely expected following the information industry and the automobile industry after the highest revenue items.

Secondary battery as a breakthrough in the stock market

The securities industry generally considered secondary battery industry is a "trend", which are short-term concern with those who have a fundamentally  BATCL50L， BATBL50L6， LCBTP03003themes. With the domestic companies to obtain operating results one after another, the public faith in the secondary battery is also stronger.

The industry's leading enterprises are LG Chemical. Earlier this year, the business with General Motors (GM) signed a battery car "Chevrolet" supply lithium-ion battery contracts. Last month, the company has been selected from the 2011 production of the Buick's battery supplier. In addition, Samsung SDI is also the beginning of last month, with the German auto parts company Bosch cooperation, and strive from the start in 2020 to provide for the BMW car battery battery project.

In the stock market, these projects became the core of a leading stake in an instant. 9, Samsung SDI's share price has risen to ₩ 165,000, while in the last year, the stock just ₩ 55,000. LG Chemical's share price is also from the end of last year ₩ 71,000 up to ₩ 212,000. Nobunaga Securities analyst Cho Yong-jun said: "IT industry and the automotive industry's share price has been greater development, investors have increased the possibility of a higher secondary battery as a long-term investment   BTP-43D1， Aspire 3000 batteryprojects." In high-Nasdaq market, and secondary battery-related parts companies have reached the highest value of shares.

Secondary battery initiative competition will spread to other countries

Rechargeable battery industry is looking forward to play the role of industrial reform. If the car battery from oil-based turn-based, oil refining, energy and other related industries will undergo significant changes. • Berkshire Hathaway chairman Warren Buffett • concern about the development trend of secondary batteries in cell vehicles in China last year bought the company BYD10% of the shares.

Around the secondary battery and start the competition is expected to expand to other countries. U.S. and Japanese government has for http://www.digital-battery.net/ the development of advanced battery projects huge budget, China's secondary battery was to ensure that the core material - to have a large number of lithium and lithium mine in Bolivia, provided construction funds.

Nickel-cadmium battery

Nickel-cadmium battery is present in the negative cadmium (Cd) and sodium hydroxide (NaOH) in the hydroxide ion (OH-) generating hydroxide compounds, cadmium, and that this compound attached to the anode, and can also release e. E-flow along the wires to the  digital camera battereiscathode, with cathode nickel dioxide and sodium hydroxide solution in the water reaction, and then produce nickel hydroxide and the hydroxide ion, nickel hydroxide will be adsorbed on the anode, so that hydroxyl ions also Huitang to the sodium hydroxide solution, the resulting concentration of sodium hydroxide solution does not change over time wastage.

Nickel-cadmium batteries were the first used in mobile phones, laptop computers and other equipment, the battery type, which has excellent high-current discharge characteristics, resistance to over charge and discharge capability and easy maintenance. Nickel-cadmium batteries of the most fatal flaw is that in the charge-discharge process if not handled properly, there will be serious "memory effect", makes the service life shortened. The so-called "memory effect" is the battery in the charge before the battery power has not been completely exhausted, the battery capacity over time will cause the reduction Dell Inspiron E1705 battery，Dell Latitude D410 batteryof the battery charge and discharge process (discharging more obvious), would be very on-board battery is some of small bubbles, these bubbles accumulate and reduce the size of the battery plates also indirectly affect the battery capacity. Of course, we can control the charge and discharge reasonable way to reduce the "memory effect."

In addition, cadmium is toxic and, therefore, nickel-cadmium battery is not conducive to the ecological environment protection. Since traditional sintering process is extremely negative, cadmium and coarse grains, if the nickel-cadmium battery is fully discharged before they are re-charging, easy to gather Manifold Ershi grain cadmium battery discharge formed when the secondary discharge plateau. Discharge the battery will be stored in this platform and in the next cycle will end as a discharge, although the capacity of the battery itself, can make the battery discharge to a lower platform. In the subsequent discharge process in the battery will only remember the low volume. Similarly, every time you use, any one not fully discharge all will deepen this effect, so that the battery capacity becomes lower.

Nickel-cadmium battery cathode active material from the board of nickel oxide powder and graphite powder composition, graphite not participate in chemical reactions, whose main role is to enhance the conductivity. Negative electrode active material from the board of cadmium oxide powder and iron oxide powder composition, the role of iron oxide powder is to cadmium Dell Latitude D500 battery， Dell Latitude D505 battery oxide powder have a higher proliferation, prevent clotting, and increase the plate capacity. Active substances were wrapped in perforated steel, the compression molding was turned into positive and negative battery plate. Between plates of hard rubber insulation with alkali-stick or a hole PVC corrugated plates separated. Electrolyte is usually potassium hydroxide solution. Compared with other batteries, NiCd batteries self-discharge rate (ie, the battery loses charge when not in use rate) moderate. NiCd batteries in the use of process, if not completely discharge on another charge, discharge next time, you can not release all the power. For example, the release of 80% of the electricity and then fully charged, the battery will only emit 80% of the electricity. This is the so-called memory effect.

Finally talk about the packaging under the nickel-cadmium batteries, which contains retail use of the positive convex head plate, and assembly used in both positive Flat packaging, they in terms of volume, and there is no difference. In the charge back on the road is also similar with the nickel-metal hydride batteries. But one thing is different is that nickel-cadmium battery memory effect than Ni-MH battery should be obvious. Therefore, to ensure that life will not be affected, then they would pay attention to daily maintenance in the use of electricity before carrying it out completely without charge.

Great demand for battery monitoring chip

Almost all energy sources (solar, wind, geothermal, nuclear, oil, gas ... etc.) can be converted into electricity. If the battery technology continues to progress, as well as be able to store a large number of reliable and economical power, then all these energy sources can be used  toshiba PA3421U-1BRS battery， toshiba PA3534U-1BRS battery，interchangeably. For high-power battery applications, lithium-ion batteries is expected to become the preferred battery at any time, mainly because of its high energy density; lithium-ion battery energy density is almost nickel-metal hydride batteries (nimh) twice, which was today's number of hybrid electric vehicles in widespread use. However, in order to make thousands of lithium-ion battery charge and discharge cycles to maintain the reliability, the battery must be designed to solve many important problems.

High-power lithium battery systems face a challenge

Lithium-ion battery performance depends on the battery temperature and the aging degree, the battery charge and discharge rate, as well as toshiba PA3591U-1BRS battery， toshiba PA3465U-1BRS batterystate of charge (soc). These factors are not independent of each other. Therefore, the lithium-ion battery charge state generally capped at 20% to 90% range, which effectively provides the capacity to provide an up to 70% of available capacity.

In order to provide a lot of power electrical systems, such as the need to accelerate a car would require up to several hundred volts. Such as: In the 1v to provide 1kw power needs 1000a currents, in the 100v only need to provide 1kw power 10a currents. Systems and interconnection lines will be translated into the intrinsic resistance of ir loss, therefore, designers can be used to achieve the highest voltage / low current.
