Analysis Of The Advantages And Disadvantages Of Lithium Cobalt Oxide Batteries

Lithium cobalt oxide battery is a kind of lithium ion battery.

Lithium cobalt oxide battery has a stable structure, high specific capacity, outstanding comprehensive performance, but its safety is poor, and the cost is very high. It is mainly used for small and medium-sized batteries, and is widely used in notebook computers, mobile phones, MP3/4 and other small electronic devices. Said voltage is 3.7V.

With the advancement of lithium battery technology, lithium cobalt oxide battery materials are basically selected as the liquid phase synthesis process of layered structure lithium ion secondary battery cathode material (lithium cobalt oxide) in the current commercial lithium ion batteries. It uses polyethylene Alcohol (PVA) or polyethylene glycol (PEG) aqueous solution is the solvent, lithium salt and cobalt salt are respectively dissolved in PVA or PEG aqueous solution, the mixed solution is heated and concentrated to form a gel, and the resulting gel is heated again It is decomposed, then burned at high temperature, and the burned powder is ground and sieved to obtain lithium sulphate powder.

The characteristics of lithium cobalt oxide batteries are as follows:

1. Superior electrochemical performance

2. Excellent processing performance

3. The tap density is large, which helps to increase the battery volumetric capacity

4. Stable product performance and good consistency

There are three disadvantages:

1. Poor security

2. High cost

3. The cycle life is average, and the material stability is not very good
