摘要：
A separator for a rechargeable battery includes a porous substrate and a heat-resistance layer on at least one surface of the porous substrate. The heat-resistance layer includes a binder having a cross-linked structure, a sphere-shaped filler, and a plate-shaped filler, and the plate-shaped filler is included in a smaller amount than the sphere-shaped filler in the heat-resistance layer. A rechargeable battery includes the separator.
