Abstract
A process for producing a lithium manganese oxide with a spinel structure for use as a cathode material of an organic electrolyte lithium ion secondary battery, which comprises: mixing at least one lithium compound selected from the group consisting of lithium hydroxide and lithium carbonate with manganese dioxide in a solvent consisting essentially of water or an aliphatic lower alcohol having from 1 to 3 carbon atoms or a mixture thereof, optionally in the presence of at least one organic acid selected from the group consisting of formic acid and acetic acid; allowing the resultant mixture to form a gel-like mixture; and drying the gel-like mixture as required; and calcining the resulting product.
