Abstract

The present disclosure provides a separator, a battery, an energy storage device, and an electric equipment comprising the same. The separator comprises a substrate film and a dot-coated adhesive layer, wherein the dot-coated adhesive layer is disposed on at least one surface of the substrate film. The dot-coated adhesive layer comprises a plurality of adhesive dots distributed in a dot matrix, and the adhesive dots have a first annular structure. The distance between an outer edge of the first annular structure and a center of the adhesive dot is R<1>, the distance between an inner edge of the first annular structure and the center of the adhesive dot is R<2>, and 0.15≤1-R<2>/R<1>≤0.35. The dot-coated adhesive layer comprises a polymer binder and an auxiliary agent, and the auxiliary agent comprises at least one of a water-soluble coupling agent and a phosphate-based auxiliary agent.
