Abstract
Disclosed are a composition, a composite separator and a preparation method therefor, and a lithium ion battery. The composition includes 10-100 parts of a polymer resin, 0.5-10 parts of a polymer adhesive, 0-50 parts of an inorganic nanoparticle powder, and 0-40 parts of nanowires. The polymer resin includes a low melting point polymer and a high melting point polymer, wherein the low melting point polymer and the high melting point polymer are the same substance; the weight ratio of the low melting point polymer to the high melting point polymer is (5-90):(10-95), the melting point of the low melting point polymer is 145° C. or less, and the melting point of the high melting point polymer is in the range of 146-500° C.
