BINDER COMPOSITION FOR SECONDARY BATTERY, SECONDARY BATTERY ELECTRODE MIX COMPRISING SAME, AND SECONDARY BATTERY

To provide a binder composition for a non-aqueous secondary battery in which adhesion between an electrode active material and a current collector is excellent, the degree of swelling of an electrode with an electrolytic solution at a high temperature is small, and a practical performance is sufficiently exhibited; an electrode mixture for a non-aqueous secondary battery obtained by using such a composition; a process for producing an electrode for a non-aqueous secondary battery; and a non-aqueous secondary battery. A binder composition for a non-aqueous secondary battery, which comprises a binder made of a fluorinated copolymer having repeating units derived from tetrafluoroethylene and repeating units derived from propylene, and a solvent or dispersing medium, wherein the fluorinated copolymer has a weight average molecular weight of from 10,000 to 300,000; an electrode mixture for a non-aqueous secondary battery obtained by using such a composition; a process for producing an electrode for a non-aqueous secondary battery; and a non-aqueous secondary battery.
