description A silicon negative electrode comprises a current collector coated with a negative electrode material. The negative electrode material comprises a silicon negative active material and a binder. The binder comprises a first polymer, a second polymer, and a third polymer. The first polymer comprises a fluorine-containing monomer. The second polymer comprises a monomer selected from the group consisting of acrylonitrile, methacrylonitrile, acrylates, methacrylates, and combinations thereof. The third polymer is selected from the group consisting of polyvinylpyrrolidone, polyalkylidene glycol, polyacrylamide, polyethylene glycol, and combinations thereof.
