Lithium cobalt oxide, generally referring to lithium cobalt oxide, is an inorganic compound with the chemical formula LiCoO2. It is a good positive electrode material in lithium-ion batteries, with advantages such as high working voltage, smooth discharge, high specific energy, and good cycling performance. However, it has high cost (using cobalt), poor safety, average cycling life, and poor material stability.

physical property:

Appearance: Dark blue or gray black powder

Density: The theoretical density is about 5.1 g/cm ³, and the actual compacted density can reach 4.2 g/cm ³

Solubility: Insoluble in water, ethanol, and ammonia, soluble in acidic or strongly alkaline solutions

chemical property:

Oxidicity: Can be used as a strong oxidant under acidic conditions

Thermal stability: can decompose into metallic cobalt and oxygen at high temperatures (such as heating)

Safety: Stable at room temperature, but avoid contact with humid environments to prevent decomposition
