Titanium acid lithium battery positive and negative plate (the positive active material are for ternary lithium, negative extremely lithium titanate), membrane, electrolyte, ear, stainless steel, aluminum alloy shell, etc Positive and negative plate is the area of electrochemical reaction, the diaphragm, electrolyte with Li + transport channel, ears have the effect of direct current.

FIG 1.

First electromotive force, the function parameters of your battery capacity, specific energy and resistanceElectromotive force is equal to the charge by the cathode through inside the battery to the positive, the battery of electrostatic force (chemical) the work done.

"At present our country is the world's largest lithium ion batteries manufacturing base, production has more than 30% of the world But the overall is still in the industrial chain of low-end and high-end and power energy storage battery larger gap, the bottleneck restricting the development of electric vehicles in China.

Scientific research shows that a button battery after abandon into nature, to 600000 liters of water pollution, equivalent to a man's life's water consumption, and every year China consumes 7 billion such two batteries, it is understood that China's production of battery is 96% zinc manganese battery and alkaline manganese battery, its main ingredients for manganese, mercury, zinc, manganese and other heavy metals Waste battery is buried in the atmosphere or buried deep in the ground, the heavy metal ingredients with drainage overflow, cause the pollution of ground and soil, accumulate over a long period will cause serious damage to human health, "the national hazardous waste list" in 1998 set of mercury, cadmium, zinc, lead, chromium as hazardous waste.

Based on the material properties of the capacitor, it can be divided into the following categories:1, aluminum electrolytic capacitor01 uF - 22000 uF capacitance range, high ripple current, long life, large capacity of choice, is widely used in power supply filter, lotus root, etc.

Lithium ion batteries as today's most successful chemical energy storage battery one of its footprint in consumer electronics products, not only more open its soil into electric carsBut the performance so outstanding lithium ion battery is very sensitive to temperature, low temperature to cause a decline in lithium ion battery performance and even lead to the lithium ion battery can't use, the low temperature charging more will lead to the production of lithium dendrite, in order to improve the low temperature performance of lithium-ion batteries, the researchers put forward a variety of measures, such as MartaKasprzyk Warsaw university of technology, people put forward the technology of amorphous electrolyte, will the use of the electrolyte temperature to expand to - 60 ℃, Shanghai university professor Xia Yong yao, the ethyl acetate, electrolyte, will further reduce the special material of battery temperature to 75 ℃, of course, not all of the research will focus on the electrolyte, the university of Pennsylvania Guangsheng Zhang and others will design a built-in Ni heating piece of battery, the battery from to 40 ℃ to recover to normal temperature only need 112 s, greatly improve the convenience of the lithium-ion batteries used in low temperature.

At present, aluminum nickel and cobalt acid lithium (NCA)The battery although the dominant in the field of electric vehicles, but it may also be replaced by other techniques For the battery management system (BMS) is usually a weak link of electric vehicle batteries.

Lead, is lithium ion polymer battery product of a raw material The lead is divided into three kinds of materials, the battery of the anode materials used aluminum (Al), the cathode materials used nickel (Ni), the cathode has copper plating nickel (Ni, Cu) materials, they are compounded by the film and the metal belt.

With the continuous improvement of new and high technology, but also because of energy conservation and environmental protection requirements, more and more energy conservation and environmental protection products have been applied to the market, in terms of battery market, lithium battery with a variety of advantages quickly replace conventional lead-acid batteries, become the main force of energy storage marketThe classification of the lithium battery has a lot of, the ternary material, lithium iron phosphate material, lithium ion, iron, manganese acid polymer lithium battery such as species.
