Abstract
A method for producing a cathode that can lower a sintering temperature is provided. The method comprises: acid-treating particles of a lithium containing composite oxide that has a layered rock-salt structure; obtaining a mixture by mixing the acid-treated particles with a lithium salt whose melting point is lower than that of the lithium containing composite oxide; and heating and sintering the mixture.
