The invention provides a conductive resin composition for an electrode, which is excellent in dispersibility and oxidation resistance. Provided are an electrode composition using the conductive resin composition for an electrode, which has a low viscosity, an electrode using the electrode composition, which has a low plate resistance, and a lithium ion battery having a high energy density, high output characteristics, and high cycle characteristics. A conductive resin composition for an electrode, characterized in that the conductive resin composition for an electrode comprises a dispersant, a conductive agent and a binder, the dispersant comprises a graft copolymer in which a monomer containing acrylonitrile as a main component is grafted to polyvinyl alcohol, the polyvinyl alcohol has an average polymerization degree of 300 to 3000 and a saponification degree of 90 to 100 mol%, the graft copolymer contains 10 to 40 mass% of polyvinyl alcohol and 90 to 60 mass% of polyacrylonitrile. |
