Abstract: An electrode assembly and a processing method and apparatus therefor, a battery cell, a battery, and a power consuming device are provided. The processing method includes: applying an adhesive on a preset part of a surface of a member to be coated, the adhesive forming a barrier layer, and the member to be coated including at least one of a cathode plate, a separator, and an anode plate; and winding the cathode plate, the anode plate, and the separator to form an electrode assembly. The barrier layer is located between the cathode active material layer and the anode active material layer adjacent to each other after the winding. The barrier layer blocks at least some ions de-intercalated from the cathode active material layer located on one side of the barrier layer from being intercalated into the anode active material layer located on the other side of the barrier layer.

Abstract: The present application provides an electrode assembly and a processing method and apparatus therefor, a battery cell, a battery, and a power consuming device. The electrode assembly includes: a cathode plate, an anode plate, and a separator, where the separator is configured to separate the cathode plate from the anode plate, a closed-pore portion is provided in part of the region of the separator, and the closed-pore portion is configured to block at least some ions de-intercalated from the cathode plate located on one side of the closed-pore portion from being intercalated into the anode plate located on the other side of the closed-pore portion. Heating the separator to form the closed-pore portion can reduce the occurrence of lithium precipitation.
