SAFE LITHIUM-ION BATTERY (LIB) SEPARATOR, FABRICATION METHOD THEREOF, AND LIB

The present disclosure discloses a safe lithium-ion battery (LIB) separator, a fabrication method thereof, and an LIB, and relates to the technical field of LIBs. The fabrication method includes the following steps: S1: preparation of a water-based slurry: mixing a ceramic material, magnesium oxide, conductive carbon black (CB), and a water-based adhesive, and thoroughly stirring to obtain the water-based slurry; S2: fabrication of a first film: adding trans-1,4-polyisoprene, cis-polybutadiene rubber (cis-BR), conductive CB, and a water-soluble salt to a compounding granulator for compounding to prepare a memory material; and mixing a high-polymer particle with the solid material, adding a resulting mixed material to a film-blowing machine, blowing the mixed material of the high-polymer particle and the solid material into a film by a film-blowing method, and watering and drying the film to obtain the first film; S3: fabrication of a second film; and S4: fabrication of the LIB separator. The present disclosure can block a reaction of an electrolyte when a temperature rises, such as to play the role of protecting batteries.
