Zusammenfassung:	The present disclosure relates to the field of lithium battery separators, and aims to provide a battery separator and a coating process thereof, a coating system and a battery. The coating process includes: initial heat setting of a polyolefin membrane, online coating of the polyolefin membrane, and heat setting of a coating membrane. The coating system includes a plurality of drying ovens disposed in a travel route of heat setting of a polyolefin membrane, and a coating apparatus for coating a coating slurry on the polyolefin membrane, which is disposed at a spacing position of adjacent drying ovens. When the online coating flow is disposed before the end of the heat setting of the polyolefin membrane, the polyolefin base membrane and the coating slurry are dried by using the temperature of the heat setting drying oven of the polyolefin membrane.
