Abstract

To provide metal-containing trimanganese tetraoxide combined particles with which a metal-substituted lithium manganese oxide excellent as a cathode material for a lithium secondary battery can be obtained, and their production process. Metal-containing trimanganese tetraoxide combined particles containing a metal element (excluding lithium and manganese). Such metal-containing trimanganese tetraoxide combined particles can be obtained by a production process comprising a crystallization step of crystalizing a metal-substituted trimanganese tetraoxide not by means of metal-substituted manganese hydroxide from a manganese salt aqueous solution containing manganese ions and metal ions other than manganese.
