Abstract
An electrochemical element with improved energy density is provided. The electrochemical element has electrochemical cells which are multiply stacked. The electrochemical cell is stacked with the full cell or bicell as a basic unit and a separator film is interposed between the adjoining portion of the cells. The electrochemical element is easy to manufacture, has a structure which uses the space available efficiently, and can maximize the content of the active electrode material so that a highly integrated battery can be implemented.
