PURPOSE:To provide a nonaqueous electrolyte secondary battery in which active materials scarcely peel out of current collectors during the repeat of charge/ discharge cycles and which has excellent charge/discharge cycles. CONSTITUTION:Regarding a nonaqueous electrolyte secondary battery provided with a negative electrode 1, a positive electrode 2, and a nonaqueous electrolytic solution, wherein the negative electrode 1 is prepared by keeping a negative electrode mix consisting of a negative electrode active material and a binder in a negative electrode current collector and the positive electrode 2 is prepared by keeping a positive electrode mix consisting of a positive electrode active material and a binder in a positive electrode current collector; polyfluorovinylidene having hydroxyl group and thermally cross-linked with a polymer having isocyanate group is used as the binder to be contained in the nagative electrode mix and the positive electrode mix. |
