Claim 14:
15. The method according to claim 14, wherein etching the anode material layer and at least one side surface of the first separation material layer comprises:
forming a first mask on one side of the anode material layer away from the substrate, wherein the anode material layer comprises a first anode material layer covering the planarization layer, and a second anode material layer adjacent to the first anode material layer and covering the one or more separators, and the first mask exposes a portion of the first anode material layer;
performing a first etching, with the first mask as a mask, on the exposed portion of the first anode material layer to form the anode;
removing the first mask;
forming a second mask covering the anode, wherein the second mask exposes the second anode material layer and a remaining portion of the first anode material layer;
perform a second etching, with the second mask as a mask, on the second anode material layer, the remaining portion of the first anode material layer, and the at least one side surface of the first separation material layer to form the first separation layer; and
removing the second mask.
