摘要：
A method for manufacturing a positive electrode active material for a nonaqueous electrolyte secondary battery including the steps of mixing a lithium source and a tetravalent manganese source and reacting the lithium source and the manganese source at a temperature lower than 600° C. while tetravalent manganese is reduced, so as to produce a lithium manganese compound oxide, wherein the positive electrode active material is formed from the lithium manganese compound oxide where the lithium manganese compound oxide is represented by a general formula LixMnO2 (x≧1) and which has a crystal structure of a space group C2/m.
