Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a nonaqueous electrolyte battery capable of restraining capacity fall at the time of preservation at high temperature. SOLUTION: In the nonaqueous electrolyte battery, a cathode active material layer 33B includes one or two kinds or more of cathode materials capable of occluding and discharging lithium, and a compound having a pyrrolidone frame as a cathode active material, and may also include other materials such as a binder and a conductive agent as the need arises. Polyacid and/or a polyacid compound are added inside the battery. COPYRIGHT: (C)2011,JPO&INPIT
