<P>PROBLEM TO BE SOLVED: To provide a flat type nonaqueous electrolyte solution secondary battery which is superior in high load characteristics by reducing internal resistance of the flat type nonaqueous electrolyte solution secondary battery. <P>SOLUTION: The flat type nonaqueous electrolyte solution secondary battery is provided which is superior in the high load characteristics by reducing the internal resistance of the battery by using a press molding product produced by pressure-molding a mixture made of spinel type lithium titanate, a conductive agent, and an ethylene-methacrylate copolymer as an electrode for heat-treating the electrode from 120 to 190°C and preferably from 150 to 170°C in the flat type nonaqueous electrolyte solution secondary battery in which lithium titanate having a spinel type structure shown by a chemical formula Li<SB>4</SB>Ti<SB>5</SB>O<SB>12</SB>is used as an active material. <P>COPYRIGHT: (C)2007,JPO&INPIT |
