Lithium cobalt acid battery is a kind of lithium-ion battery.
Lithium cobalt acid battery structure is stable, high specific capacity, outstanding comprehensive performance, but its safety is poor, the cost is very high, mainly used in the small and medium-sized cell, widely used in notebook computers, mobile phones, MP3/4 and other small electronic equipment, nominal voltage 3.7V.
With the progress of lithium-ion battery technology, cobalt acid lithium battery materials basically use in the current commercial lithium-ion battery of layered structure of lithium-ion secondary battery cathode material (cobalt acid lithium) liquid-phase synthesis process, it USES polyvinyl alcohol (PVA) aqueous solution of polyethylene glycol (PEG) as solvent, lithium, cobalt salts are dissolved in PVA or PEG in aqueous solution, The mixed solution is heated and concentrated to form a gel. The gel generated is then heated and decomposed, and then burned at high temperature. The sintered powder is ground and screened to get lithium drilling acid powder.
Lithium cobalt oxide battery features the following four aspects:
1. Excellent electrochemical performance
2, excellent processing performance
3, the vibration density is large, which helps to improve the specific volume capacity of the battery
4. The product has stable performance and good consistency
There are three disadvantages:
1. Poor security
2. High cost
3, the cycle life is general, the material stability is not good
