Abstract: A polyolefin-based film is described. Through optimization of tortuosity of a pore structure in the polyolefin-based film, the polyolefin-based film has a uniform pore structure, thereby improving consistency of the base film, reducing performance deviation of the base film, and effectively ensuring air permeability of the base film.

When the polyolefin-based film is used as a separator in a battery, electrical performance of the battery can be improved, including reducing battery internal resistance, direct current resistance, self-discharge rate, short-circuit rate, and the like.
