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

A safe lithium-ion battery (LIB) separator, a fabrication method thereof, and an LIB are provided. The fabrication method includes: 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; adding the memory material to a mixed solution of aluminum nitride and ethanol, and conducting stirring, suction filtration, drying and calcination to obtain a solid material; and mixing a high-polymer particle with the solid material, adding a resulting mixed material to a film-blowing machine, blowing into a film, and watering and drying the film to obtain the first film; S3: fabrication of a second film; and S4: fabrication of the LIB separator.
