An electrode assembly is provided to reduce the failure rate of battery and to improve processability in manufacturing the battery by using a separation film sheet. An electrode assembly(500) is manufactured by winding a plurality of bi-cells with a separation film sheet of the long length and welding the electrode taps to an electrode lead(400). The bi-cell positioned in the outermost of the electrode assembly has different materials of the intermediate layer plate and the electrode lead. Relatively, the thickness of the intermediate layer plate is thicker than the plate corresponding to the other bi-cells. |
