Abstract: A separator includes: a first porous substrate; and a second porous substrate arranged on at least one surface of the first porous substrate; wherein the elongation at break of the second porous substrate is greater than the elongation at break of the first porous substrate in at least one of the machine and transverse directions of the separator. The separator has a high tensile strength and an elongation at break and good heat resistance, and may improve the safety performance of the energy storage device when the separator is applied to the energy storage device.
