Document Type and Number:
Japanese Patent JP6926509
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a power storage device which enables the enhancement in sealability between bipolar electrodes.SOLUTION: A power storage device 1 has bipolar electrodes 14 each including an electrode plate 15 in which electrodes 16, 17 differing from each other in polarity are formed on one face 15a and the other face 15b respectively. The power storage device 1 comprises: an electrode laminate 11 arranged by stacking the bipolar electrodes 14 through a separator 13; and a sealing body 12 provided on a side face 11a of the electrode laminate 11 so as to surround edge parts 15c of the bipolar electrodes 14. In the bipolar electrode 14, the edge part 15c of the electrode plate 15 is provided with a protrusion 23 protruding from at least one of the one face 15a and the other face 15b; the sealing body 12 is bonded to the edge part 15c of each bipolar electrode 14 with the protrusion 23 buried in the sealing body 12.SELECTED DRAWING: Figure 3
