Abstract
Disclosed is an electric energy storage device having a large capacity and includes a thin active material layer and a plurality of integrated electrodes. The electric energy storage device comprises at least one electrode group in which a cathode, a separator and an anode are in regular sequence, repeatedly integrated and wound into a plate shape. The electrode group has lead lines collected at a predetermined place for a connection with a terminal. Since the cathode and anode are wound with the insertion of the separator between them, the increase of the number of the lead lines is advantageous. In addition, the lead lines can be preferably formed by cutting each portion of the electrode at once by utilizing an apparatus such as a press, the manufacture of the electric energy storage device having a large capacity is advantageous.
