PROBLEM TO BE SOLVED: To provide a nonaqueous electrolyte secondary battery, having a positive active mixture or a negative active mixture keeping physical properties such as chemical resistance, heat resistance, oxidation resistance and the like which are required in a binder used for the electrode of the nonaqueous electrolyte secondary battery, and superior in an adhering property to a current collector metal and flexibility. SOLUTION: A binder, contained in a negative electrode mixture and/or a positive electrode mixture, comprises a binder resin composition prepared by adding an isocyanate compound or an amino resin in at least one kind of resin selected from a fluorine-containing copolymer prepared by copolymerization of vinylidene floride, chloro-trifluoro ethylene and unsaturated peroxide, and a graft copolymer resin provided by cleaving a peroxy group, contained in the fluorine containing copolymer used as a base resin to graft-polymerize an olefin, using the fluorine containing copolymer as the base resin. |
