▎ 摘　　要

NOVELTY - Lithium ion battery binder comprises 1-49 pts. wt. unsaturated siloxane, 1-49 pts. wt. propylene monomer, 50-150 pts. wt. N-methylpyrrolidone and 0.1-0.5 pts. wt. initiator. USE - The lithium ion battery binder is useful in preparation of lithium-ion battery anode sheet and lithium-ion battery cathode sheet (all claimed). ADVANTAGE - The lithium ion battery binder: contains unsaturated siloxane, in which the siloxane functional group is hydrolyzed and reacts with the groups on the surface of the positive and negative materials to form a stable chemical bond connection, which provides excellent bonding effect. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) preparing the lithium ion battery binder comprising mixing unsaturated siloxane, propylene monomer, and N-methylpyrrolidone to obtain a raw material mixed solution, adding initiator to raw material mixed solution for polymerization reaction to obtain a binder; (2) use of lithium ion battery binder in preparation of lithium-ion battery anode sheets, the binder comprises above mentioned raw materials; and (3) use of lithium ion battery binder in preparation of lithium-ion battery cathode sheets, the binder comprises above mentioned raw materials.
