Original Abstract Submitted
A power storage device comprises: an electrode stack comprising a plurality of bipolar electrodes and a pair of outermost current collectors; an inner voltage detection terminal; a housing; and a pair of outer voltage detection terminals. Each of the plurality of bipolar electrodes has a current collector, a positive electrode active material layer, and a negative electrode active material layer. The inner voltage detection terminal is electrically connected to the current collector. Each of the pair of outer voltage detection terminals is thicker than the inner voltage detection terminal. The housing is located between the pair of outer voltage detection terminals in the stacking direction. A dimension of the housing in the stacking direction is equal to or less than a distance between the pair of outer voltage detection terminals in the stacking direction.
