Original Abstract Submitted

A positive electrode active material with high charge and discharge capacity is provided. A novel positive electrode active material is provided. The positive electrode active material is manufactured in such a manner that after a cobalt compound (also referred to as a precursor) containing nickel, cobalt, and manganese is obtained by a coprecipitation method, a mixture obtained by mixing a lithium compound and the cobalt compound is heated at a first temperature; after the mixture is ground or crushed, heating at a second temperature that is a temperature higher than the first temperature is further performed; and after an additive is mixed, third heat treatment is performed. The first temperature is higher than or equal to 400° C. and lower than or equal to 700° C. The second temperature is higher than 700° C. and lower than or equal to 1050° C.
