Disclosed herein are an
electrode assembly including a plurality of unit cells folded by a continuous separation film wherein the unit cells are arranged on the separation film such that
electrode taps of the unit cells face each other, the separation film has openings corresponding to the
electrode taps of the unit cells, and the electrode
assembly is manufactured by folding the unit cells in the longitudinal (lengthwise) direction of the separation film while the unit cells are disposed such that the electrode taps of the unit cells are inserted into the corresponding openings, and an
electrochemical cell, such as a secondary battery, including the same. The electrode
assembly according to the present invention is a
hybrid type electrode assembly solving the problems of the jelly-roll type electrode assembly and the stacking type electrode assembly. Consequently, when external impacts are applied to the electrode assembly, for example, the electrode assembly falls, it is possible to minimize the occurrence of internal short circuits and thus to improve the safety of the electrode assembly. Furthermore, it is possible to perform the process for impregnating (
wetting) the
electrolyte into the electrodes in a short time during the assembly of the
electrochemical cell.
