PURPOSE:To improve the manufacture of the positive electrode active material of a nonaqueous electrolyte secondary battery and enhance the charge/discharge cycle property of the battery. CONSTITUTION:In an aqueous electrolyte battery, which contains lithium, oxide, lithium alloy, or the like as a negative pole, and lithium salt as a nonaqueous electrolyte, and uses formula LixMn(2-yMyO4 (but, M is, at least, one kind of element selected from Co, Ni, Fe, and Cr, and 0.85<=X<=1.15 and 0.02<=y<=0.3) as an active material, as the starting material of Mn, at least, one of electrolyte manganese dioxide and Mn2O3 is used. |
