Abstract

The method for manufacturing a particulate electrode active material provided by the present invention uses a carbon source supply material prepared by dissolving a carbon source () for forming a carbon coating film in a predetermined first solvent, and an electrode active material supply material prepared by dispersing a particulate electrode active material () in a second solvent that is compatible with the first solvent and is a poor solvent with respect to the carbon source. The carbon source supply material and the electrode active material supply material are mixed and a mixture of the electrode active material and the carbon source obtained after the mixing is calcined, thereby forming a conductive carbon film derived from the carbon source on the surface of the electrode active material.
