Abstract
A separator for an energy store. The separator may be used in a lithium-sulfur battery in particular. To achieve improved cycle stability, the separator has at least one first layer and at least one second layer, the at least one first layer containing a material having an affine property with respect to at least one active electrode material, and the at least one second layer containing a material having a repellent property with respect to at least one active electrode material. The at least one first layer and the at least one second layer may be situated directly adjacent to one another. Also described is an energy store including the separator.
