Abstract
A process for producing lithium manganate, comprising pulverizing electrodeposited manganese dioxide by causing particles of electrodeposited manganese dioxide to collide with each other to produce a pulverized material, screening the pulverized material to an average particle size of 3 to 20 &mgr;m thereby to produce a screened material, mixing the screened material with the lithium raw material to form a mixture, and firing the mixture to produce lithium manganate. During screening, electrolytic manganese dioxide having an average particle size smaller than 3 &mgr;m is removed from the screened material.
