Abstract:
A binder composition for positive electrode with superior oxidation resistance is provided. A slurry for positive electrode, a positive electrode, and a lithium ion secondary battery manufactured by using the binder composition is provided. A binder composition for positive electrode including a graft copolymer in which a monomer containing acrylonitrile as a main component is graft copolymerized with polyvinyl alcohol having an average degree of polymerization of 300 to 3000 and a saponification degree of 70 to 100 mol %, is provided. Further, a slurry for positive electrode includes the binder composition for positive electrode, a positive electrode active material, and a conductive assistant. In addition, a lithium ion secondary battery is manufactured using a positive electrode made with the slurry for positive electrode and a positive electrode.

Claim (Index 2):
The binder composition for positive electrode of  claim 1 , wherein:\n the graft copolymer has a graft rate of 150 to 900%; and a homopolymer of polyacrylonitrile generated during the graft copolymerization has a mass average molecular weight of 30000 to 250000.
