TRIMANGANESE TETRAOXIDE AND METHOD FOR PRODUCING SAME

摘要

To provide trimanganese tetraoxide from which a lithium manganese oxide with less fusion of particles by firing i.e. necking phenomenon is obtained. Trimanganese tetraoxide characterized in that the pore volume of pores having pore diameters of from 0.3 to 2 µm is at least 0.1 mL/g. The pore volume of pores having pore diameters of from 0.5 to 1 µm is preferably at least 0.03 mL/g.
