Abstract
A method for manufacturing positive a electrode active material for a lithium battery represented by general formula Li.sub.x Mn.sub.2-y M.sub.y O.sub.4 (M: a 2-valency metal, 0.45.ltoreq.y.ltoreq.0.60, 1.ltoreq.x.ltoreq.2.1) having cubic spinel structure of and a lattice constant within 8.190 angstroms by employing a solid phase reaction, comprising the steps of firing a lithium compound, a manganese compound and a metal M compound and refiring the fired material after pressurizing it at least once to remove a metal M oxide.
