Coating Liquid for Use in Lithium Ion Battery, Lithium Ion Battery Separator, and Lithium Ion Battery

Abstract

Disclosed are a coating liquid of a lithium ion battery separator, a lithium ion battery separator, and a lithium ion battery. The raw materials of the coating liquid include a nanowire, ceramic powder, an adhesive, and a solvent; the nanowire is at least one of nano cellulose, carbon nanotube, silver nanowire, boron carbide nanowire, copper hydroxide nanowire, aramid nano fiber, silicon monoxide nanowire, and hydroxyapatite nanowire; the diameter of the nanowire is 1-100 nm, and the length is 0.1-100 μm. The lithium ion battery separator consisting of a separator body and a coating layer loaded on the separator body is obtained by applying the coating liquid that is obtained by mixing the nanowire, the ceramic powder, the adhesive and the like onto the surface of the separator body, and performing curing; the lithium ion battery has good thermal stability and puncture resistance, etc.
