    • The present invention relates to an electrochemical element, specifically an electrochemical element with improved energy density comprising stacked electrochemical cells. In order to achieve such objects, the present invention provides an electrochemical element comprising electrochemical cells which are multiply stacked, said electrochemical cells formed by stacking full cells or bicells having a cathode, a separator layer, and an anode sequentially as a basic unit, and a separator film interposed between each stacked cell wherein, said separator film has a unit length which is determined to wrap the electrochemical cells, and folds outward every unit length to fold each electrochemical cell in a Z-shape starting from the electrochemical cell of a first spot to the electrochemical cell of the last spot continuously while the remaining separator film wraps an outer portion of the stacked cell and a method for manufacturing the same.
