A separator (10) includes a first base film (11) and a second base film (12), where a melting point of the second base film (12) is higher than a melting point of the first base film (11), and a creep flexibility of the first base film (11) is larger than a creep flexibility of the second base film (12). The first base film (11) and the second base film (12) have different creep flexibility, so that the two base films have different deformability under the action of a stress. Stress buffering of one layer of base film and strength support of the other layer of base film jointly suppress damage to the separator caused by dendrites and reduce the risk of a short circuit caused by the dendrites penetrating the separator, thereby improving the reliability and cycle life of a battery.
