Abstract

Disclosed herein is 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 electrochemical cells, 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. The electrode assembly is manufactured with high productivity while the electrode assembly exhibits performance and safety equal to those of a conventional stack/folding type electrode assembly.
