  "textContent": "The present disclosure relates to a composite lithium battery separator and a preparation process therefor. The composite lithium battery separator includes a base film or a ceramic film, and a coating layer covering one side or both sides of the base film or the ceramic film. The coating layer is formed by coating a slurry. The slurry includes 5%-45% by weight of a coating polymer and 55%-95% by weight of an organic solvent, and the coating polymer includes 10-100 parts by weight of a fluorine or acrylic resin polymer, 0.5-10 parts of a polymer adhesive, and 0-90 parts of inorganic nanoparticles.",
