<P>PROBLEM TO BE SOLVED: To provide a nonaqueous electrolytic battery which obtains sufficient cycle characteristics even when a positive electrode material having an olivine structure is used. <P>SOLUTION: A negative electrode mixture layer 22B includes a carbon material having a specific surface area of 0.5 m<SP>2</SP>/g to 2 m<SP>2</SP>/g, and a high molecular compound serving as a binder that has a constitutional repeating unit derived from a vinylidene fluoride having a weight-average molecular weight of 250,000 to 350,000. <P>COPYRIGHT: (C)2009,JPO&INPIT |
