Abstract
Provided is a nonaqueous battery having an active material of a positive electrode formed from a composite powder consisting of Li.sub.1-x Mn.sub.2 O.sub.4 (0.ltoreq.X.ltoreq.1) and Li.sub.2 MnO.sub.3. Because the active material has the form of a composite, this battery allows little of the manganese to dissolve out during charge and hence has excellent charge-discharge characteristics.
