Non-aqueous electrolyte system energy device electrode binder resin composition, a non-aqueous electrolyte system energy device electrode and a nonaqueous electrolyte system energy device

An object of the present invention is excellent in swelling resistance against adhesion and electrolyte between the anode current collector, yet, that the flexibility and flexibility of the electrode to provide a good binder resin composition. Further, by using the binder resin composition, a high capacity, yet, is to provide an electrode and a nonaqueous electrolyte system energy device non-aqueous electrolyte-based energy device capacity reduction is small in charge and discharge cycles . And repeating units derived from a nitrile group-containing monomer, formula (I) (In the formula, R Repeat units and / or formula derived in monomer represented (II) (Wherein, R Provided in the repeating unit derived from a monomer represented by any of the carboxyl group-containing monomer-derived repeating unit and a non-aqueous electrolyte system energy device electrode binder resin composition comprising a copolymer containing the .
