Abstract: The power storage device includes power storage units arranged with a conductive plate interposed therebetween in the vertical direction, each of the power storage units includes an electrode stack including bipolar electrodes stacked with a separator interposed therebetween, and a sealing member provided around the electrode stack so as to seal a housing space formed between adjacent electrodes of the electrode stack. At least one of the power storage units is provided with an overhang member on an outer peripheral surface of the sealing member. The overhang member includes an inclined portion that extends from the outer peripheral surface of the sealing member toward the outside of the power storage unit and inclines downward as it leaves away from the outer peripheral surface of the sealing member, and a top portion formed at a lower end of the inclined portion.

Abstract: A power storage device includes a plurality of power storage modules laminated, a conductive plate and a sealing member. The conductive plate and the sealing member are provided between the power storage modules adjacent to each other in a laminating direction of the power storage modules. The plurality of power storage modules each have an electrode laminate, an electrolytic solution, and a sealing body. The electrode laminate has electrode exposed portions exposed from the sealing body at one end and the other end in the laminating direction. Between the power storage modules adjacent to each other in the laminating direction, the conductive plate is disposed between the electrode exposed portions opposing each other to be in contact with the electrode exposed portions, and at least a portion between the sealing bodies opposing each other is filled with the sealing member.
