  • Cathode binder composition, cathode slurry, cathode, and lithium ion secondary battery
    Patent number: 9941518
    Abstract: Cathode binder composition having excellent binding properties and oxidation resistance. Also, cathode slurry, cathode, and lithium ion secondary battery produced using the cathode binder composition. The cathode binder composition contains a graft copolymer in which a monomer containing acrylonitrile as the main component is grafted onto polyvinyl alcohol having an average degree of polymerization of 300 to 3000 and a degree of saponification of 70 to 100% by mol. The cathode slurry contains the cathode binder composition, a cathode active material, and a conductive auxiliary. The cathode is produced using the cathode slurry. The lithium ion secondary battery contains a cathode prepared in this manner.
