Abstract: A method for preparing a separator of a battery comprises the steps of: respectively stretching a first polypropylene film and a second polypropylene film in one direction at ?3-7° C., and keeping at 45-60° C. to provide a first polypropylene microporous film and a second polypropylene microporous film; perpendicularly compounding the films along the stretching direction to provide a polypropylene microporous composite film; and subjecting the polypropylene microporous composite film to hydrophilic treatment to provide the separator of the battery. The through micro-pores in the first and the second polypropylene film in the invention are attached and staggered to form tortuous pores, which greatly reduce the aperture of the through pores. Therefore, the passing of fine zinc particles and zincate can be blocked without influence on the passing of organic ions and the penetration of dendritic crystals is avoided.
