WIPO Patent Application WO/2023/246134

Kind Code:

A1

Abstract:

The present application belongs to the technical field of batteries, and relates to an electrode sheet, an electrode assembly, a battery cell, a battery, and an electric device. The electrode sheet comprises: a current collector; and an active material layer, which is coated on the surface of the current collector, wherein the active material layer comprises a first edge and a second edge, which are opposite each other in a width direction of the current collector, the first edge extending in an undulating manner in a length direction of the current collector. A battery cell, which is composed of the electrode sheet, has a relatively high safety.
