Cobalt oxide CAS 1307-96-6

Cobalt oxide is a high-valent oxide of cobalt, with a theoretical cobalt content of 71.06% and an oxygen content of 28.94%. It is a black amorphous powder. Cobalt oxide is a compound that is unstable and cannot be in a free state. Usually, cobalt oxide is attached to a certain amount of cobalt tetroxide. When heated, cobalt oxide is reduced to cobalt tetroxide. The theoretical cobalt content of cobalt tetroxide is 73.43%, the oxygen content is 26.57%, and the appearance is gray-black or black powder. The cobalt oxide used in the battery is cobalt tetroxide, which has a spinel structure. It can be used as a negative electrode material for lithium ion batteries, and it is also the main raw material for preparing lithium cobalt oxide as a positive electrode material for lithium ion batteries.
