    Abstract: A power storage device includes power storage cells and a bus bar. Each power storage cell includes positive-electrode sheets, negative-electrode sheets, a positive-electrode current collector plate, a negative-electrode current collector plate, and a laminated film. The positive-electrode current collector plate includes a positive-electrode protrusion shaped to protrude from the laminated film, and the negative-electrode current collector plate includes a negative-electrode protrusion shaped to protrude from the laminated film. The power storage cells are stacked such that the positive electrode protrusion in one power storage cell and the negative-electrode protrusion in another power storage cell adjacent to the one power storage cell face each other in the one direction. The bus bar is shaped to extend in the one direction and connects the positive-electrode protrusion to the negative-electrode protrusion.

    Abstract: This battery is provided with a power generating element, a battery case main body, a battery case lid, an electrode terminal member which is connected electrically to the power generating element inside of the battery case body and which extends outside of the battery case lid, and an outer insulation member which is arranged on the battery case lid and insulates the electrode terminal member from the battery case lid. The battery case lid is fitted inside of the opening and welded to the battery case main body by irradiating a laser from above the battery case lid towards the boundary section between the battery case lid and the battery case main body. Furthermore, this battery is provided with a plume control portion which prevents the plume that rises from the boundary portion during welding from rising towards the outer insulating member.

    Abstract: Provided is a battery pack in which multiple battery cells are electrically connected by using bus bars, with little resistance variability and without plating of electrode external terminals. A method for producing a battery pack disclosed herein includes: a step of stacking a plurality of battery cells each having a battery case and electrode external terminals provided outside the battery case; and a step of electrically connecting the electrode external terminals of the plurality of battery cells by using metal-made bus bars. The electrode external terminals are not plated. The method for producing a battery pack further includes forming a fresh surface of terminal material at each surface of the electrode external terminals; and bringing the fresh surface and each metal-made bus bar into contact with each other.

    Abstract: 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.
