Lithium battery is green battery

Lithium-ion batteries typically come in two shapes: cylindrical and rectangular. Inside the battery is a spiral wound structure, with a very fine and strong permeability of the polyethylene film insulation material in the positive and negative electrode spacing. The positive electrode includes a lithium collector composed of lithium and cobalt dioxide and an electric current collector composed of an aluminum film. The negative electrode is composed of a lithium collector composed of a sheet carbon material and a current collector composed of a copper film. The battery is filled with an organic electrolyte solution, also, equipped with a safety valve and PTC components, in order to protect the battery in abnormal state and output short circuit from damage. The voltage of a single lithium-ion battery is 3.6v, and its capacity cannot be infinite. Therefore, a single lithium-ion battery is often processed in series or in parallel to meet the requirements of different occasions.

 

Compared with the traditional secondary battery, lithium battery has outstanding advantages: the working voltage of high lithium battery is 3. 6V, three times than the operating voltage of nickel-cadmium and nickel-hydride batteries. In many small electronic products, a battery can meet the use requirements. This is also a major difference from other secondary batteries, so only lithium ion battery charger to charge, to avoid accidents. At present, the specific energy of lithium ion batteries with high specific energy has reached 140Wh/kg, which is 3 times of nickel-cadmium batteries and 1.5 times of nickel-hydride batteries. Cycle life is long at present the cycle life of lithium ion battery has reached more than 1000 times, in the low discharge depth can reach tens of thousands of times, more than several other secondary batteries. The monthly self-discharge rate of small lithium batteries is only 6-8%, which is much lower than nickel-cadmium batteries (25-30%) and nickel-hydride batteries (30-40%). No memory effect can be required to be able to charge at any time, without reducing battery performance. There is no harmful substance in the environment-friendly lithium battery, which is a veritable "green battery".
