Abstract:
1. A process for producing lithium manganate which comprises (1) the step of reacting a manganese compound with a basic compound to obtain manganese hydroxide, (2) the step of oxidizing the manganese hydroxide to obtain manganese oxide seed, (3) the step of conducting oxidation while reacting a manganese compound with a basic compound in the presence of the manganese oxide seed to cause the particle growth of the manganese oxide seed, (4) the step of reacting the manganese oxide which has undergone particle growth with a lithium compound, or the step of treating the manganese oxide with an acid to obtain proton-substituted manganese oxide and then mixing the proton-substituted manganese oxide with a lithium compound or reacting it with a lithium compound and (5) the step of firing a reaction product or a mixture obtained above with heating.
