Lithium Battery

Li-ion battery is a class of lithium metal or lithium alloy anode material, the use of non-aqueous electrolyte solution batteries. First appeared in the lithium battery from the great inventor Thomas Edison, using the following reaction: Li + MnO2 = LiMnO2 the redox reaction of the discharge. Because the chemical properties of lithium metal is very lively, making the lithium metal processing, storage, use, environmental requirements are very high. Therefore, the long-term lithium batteries have not been applied. Li-ion battery has now become mainstream. The main advantage of lithium-ion battery 1, relatively high specific energy. With high stored energy density, has now reached 460-600Wh/kg, is about 6-7 times the lead-acid batteries; 2, long service life, service life can reach more than 6 years, lithium iron phosphate as cathode of the battery charge and discharge with 1CDOD have 10,000 records can be used; 3, rated voltage high (single operating voltage of 3.7V or 3.2V), approximately equal to three nickel-cadmium or nickel metal hydride rechargeable batteries in series voltage, easy to form the battery power pack; 4, with a high power tolerance, in which electric vehicles with lithium iron phosphate lithium-ion batteries can reach 15-30C charge-discharge capacity, easy to start the acceleration of high intensity; 5, the self-discharge rate is very low, which is the most prominent advantages of the battery, the current generally be 1% / month less than nickel-metal hydride battery is 1 / 20; 6, light weight, weighing about the same volume of lead-acid products 1/5-6; 7, high and low adaptability, can be -20 °C - 60 °C environment to use, after the process on the processing environment can be used in -45 °C; 8, green, regardless of the production, use and discard, do not contain, nor have any lead, mercury, cadmium and other toxic heavy metals and substances. 9, the production of basic non-consumption of water, the water shortage in China is very favorable.
