Abstract
The disclosure provides a method for manufacturing a separator, comprising the steps of: providing a nonporous precursor substrate; coating a heat-resistant slurry on a surface of the nonporous precursor substrate to form a heat-resistant coating layer, wherein the heat-resistant slurry comprises a binder and a plurality of inorganic particles; and stretching the nonporous precursor substrate with the heat-resistant coating layer formed thereon to generate a separator comprising a porous substrate and a heat-resistant layer; wherein the heat-resistant layer is disposed on the surface of the porous substrate in the range of 10% to 90% of the total surface area of the porous substrate.
