The chemical formula of lithium cobalt oxide in lithium cobalt oxide battery is LiCo02, which is an inorganic compound commonly used as the positive electrode of lithium batteries. L-ion battery cathode material LICO02 is a high-performance liquid phase generation process. It is currently prepared from lithium magnesium aluminate in lithium-ion batteries. It uses acrylic emulsion or polyethylene glycol solution as the organic solvent and is dissolved in PVA or PEG solution. Lithium salt and drilling salt are heated and concentrated to form a gel. The resulting gel is heated and decomposed, and then calcined at high temperature. The calcined powder is ground and sieved to obtain lithium drilling oxide powder.

　　LiCoO2 is widely used in high-power lithium-ion batteries. In layered LiCoO2, lithium ions move two-dimensionally between the dense layers of CoO2 atoms. It has high operating voltage, stable charge and discharge voltage, high specific energy, and good cycle performance. advantage.

　　Reactions during the charging and discharging process of lithium phosphate batteries: Reactions during charging: positive electrode: LiCoO2=Li1-xCo02+xLi++xe-negative electrode: 6C+xLi++xe-=Lixc6. Reaction during discharge: positive electrode: Li1-xCoO2+xLi++xe-=LiCoO2, negative electrode: LixC6=6C+xLi++xe-. Advantages and disadvantages of lithium cobalt oxide battery Lithium battery: (1) Advantages of lithium cobalt oxide battery: 1.

Excellent production and processing characteristics. 3. High vibration density is conducive to improving the volume ratio of rechargeable batteries. 4. Product characteristics are stable and consistent. 5. High operating frequency, stable charging and discharging, high energy density, and good cycleability. 6. Suitable for high-flow charging and placement and sliding of lithium-ion batteries. (2) Lithium cobalt acid defects: 1. The specific capacity of LiCO2 is about 14B250A/g, which is only 5% of the basic theoretical capacity (272m/g). 2. During the entire process of battery charging, the structure of the active material changes after several convergences and rises, resulting in lico0. Internal resistance increases and volume decreases
