Abstract
A polyolefin porous separator includes a polyolefin porous base film, and a coating layer formed on one or both sides of the base film. The coating layer includes inorganic particles. The inorganic particles include first inorganic particles having an average particle size ranging from 150 nm to 600 nm, and second inorganic particles having an average particle size ranging from 5 nm to 90 nm. The separator has a thermal conductivity of 0.3 W/m·K or more.
