LAYER CELL ASSEMBLED BATTERY INCLUDING LAYER CELL AND METHOD FOR ASSEMBLING LAYER CELL

摘要

The present invention provides a layer cell capable of suppressing increases in temperature inside the cell without the need for extra space for cooling and also capable of preventing short circuits between electrodes. This layer cell is provided with an outer cover a positive electrode a negative electrode a separator disposed between the positive electrode and the negative electrode and a conductive power collector passing through the positive electrode the negative electrode and the separator along the axial direction of the outer cover. The positive electrode the negative electrode and the separator are layered in the axial direction of the outer cover. A first electrode that is either the positive electrode or the negative electrode is in contact with the inner surface of the outer cover and is not in contact with the power collector. A second electrode that is the other electrode is not in contact with the outer cover and is in contact with the power collector. The outer edge of the second electrode is covered by the separator and the peripheral edge of the hole in the first electrode through which the power collector passes is covered by the separator.
