Abstract:
1. An electrode assembly constructed in a structure in which a plurality of electrochemical cells, formed of full cells having a cathode/separator/anode structure, as basic units, are overlapped, and a continuous separator sheet is disposed between the overlapped cells, wherein in the structure before the electrochemical cells are overlapped, the full cells are configured to be placed in the same electrode orientation on the continuous separator sheet, wherein a unit electrode surrounded by the separator sheet is located at a middle of the overlapped electrochemical cells, which is a winding start point, and the full cells disposed above and below the unit electrode are symmetrical to each other about the unit electrode in the direction of electrodes of the full cells, wherein the unit electrode is an anode or cathode, and wherein anodes are located at a topmost layer and a bottommost layer of the electrode assembly to form an outer surface of the electrode assembly.
