Beschreibung
Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a battery having superior capacity and performance in high voltage area by subjecting the lithium oxide to heat treatment, the chrome oxide and the manganese oxide for a specified time in a specified temperature area, and thereafter, gradually cooling them so as to form a specified compound. SOLUTION: Heat treatment is conducted in a temperature area at 730-760 deg.C for 40-50 hours, and thereafter gradual cooling is performed to form a compound having a formula LiCrx Mn2-x O4 (0
