  "textContent": "The present invention discloses a method for preparing a composite coated separator of thermal resistance and high air permeability, comprising: preparing an MOF coating slurry and a hydrotalcite coating slurry; applying the hydrotalcite coating slurry on two sides of a base membrane through roller coating, and drying the base membrane to obtain a semi-finished hydrotalcite coated membrane; and using the semi-finished hydrotalcite coated membrane as a base membrane, applying the MOF coating slurry on two sides of the membrane through mixed coating, and drying the membrane to obtain the composite coated separator of thermal resistance and high air permeability. The composite coated separator obtained by the method has thermal shrinkage resistance and high air permeability, and can effectively improve safety performance and cycling performance of a battery.",
