ELECTRODE ACTIVE MATERIAL AND METHOD FOR PRODUCING SAME

摘要

Disclosed are an electrode active material and a method for producing an electrode active material. The method for producing an electrode active material comprises the following steps (i), (ii) and (iii). (i) An aqueous solution containing M is brought into contact with a precipitant, thereby obtaining a precipitate, wherein M represents at least two elements selected from the group consisting of metal elements other than alkali metal elements. (ii) The precipitate is mixed with a sodium compound, thereby obtaining a mixture. (iii) The mixture is calcined.
