  • Publication number: 20170204308
    Abstract: The present disclosure relates to the field of lithium-ion battery materials, and specifically relates to a lithium-ion battery bonding agent and a lithium-ion battery comprising said bonding agent. The bonding agent is a polymer comprising structural units represented by Formula I, Formula II, Formula III, and Formula IV, and has a number average molecular weight of 500,000 to 1.2 million. The present disclosure further relates to a lithium-ion battery, comprising a positive film, a negative film, a separator, and an electrolyte, the positive film comprising the bonding agent according to the present disclosure. The bonding agent according to the present disclosure can significantly improve the flexibility of a positive film, avoid processability and battery performance issues caused by the electrode film being too brittle, and help improve the compact density and battery energy density.
