Electrode assembly, battery, and electric device

Abstract

An electrode assembly, a battery, and an electric device. The electrode assembly includes a first electrode, a second electrode, a first separator, and a second separator. One of the first separator and the second separator is disposed between the first electrode and the second electrode. The other of the first separator and the second separator is disposed on a side that is of the first electrode or the second electrode and that faces away from the first separator. One of the first separator and the second separator does not include a porous coating. The other of the first separator and the second separator includes a porous coating. The thickness of the porous coating is 0.5 μm to 8 μm. The electrode assembly in the present application includes a specific first separator and a specific second separator, which can effectively improve cycling performance of the battery.
