Abstract

Provided are a separator assembly, a battery cell, a battery and an electric device. The separator assembly comprises a first separator, wherein the first separator comprises a first base film and a first coating, the first coating is located on the surface of at least one side of the first base film, the first coating comprises an inorganic material, and the volume average particle size Dv50 of the inorganic material satisfies: Dv50 ≤0.16 µm. The separator assembly can reduce the risk of short-circuiting a battery cell without deteriorating the rate performance of the battery cell, so that the battery cell has relatively good overall performance.
