Abstract: There is provided an assembled battery including a plurality of single cells and a plurality of bus bars connecting the plurality of single cells in series. The plurality of single cells is arranged such that a pair of flat side surfaces faces each other. The single cells each include a battery case, a positive electrode sheet, a negative electrode sheet, a positive electrode terminal, a negative electrode terminal, an electrical resistor disposed in a conductive path between the positive electrode sheet and the positive electrode terminal, and a pressure operative type current interruption mechanism disposed in a conductive path between the negative electrode sheet and the negative electrode terminal.

Abstract: A battery pack includes a plurality of unit cells, each including an electrode body having a structure in which a positive electrode and a negative electrode are stacked, and a busbar that electrically connects a positive electrode terminal to a negative electrode terminal between the unit cells. The unit cells are stacked adjacent to one another in the same direction as a direction in which the positive electrode and the negative electrode of the electrode body are stacked. The busbar electrically connects the unit cells disposed apart from each other among the unit cells excluding the unit cells disposed adjacent to each other.

Abstract: An assembled battery disclosed here includes a plurality of single cell array units each including single cells that are arranged in a lamination direction of a positive electrode and a negative electrode of an electrode body as an arrangement direction. The single cell array units are disposed parallel to each other such that arrangement directions of the single cells constituting the units are parallel to each other. Then, in the assembled battery, none of the single cells included in each of the single cell array units is directly electrically connected to adjacent single cells in the same unit, but is directly electrically connected to any one of the single cells constituting another single cell array unit through a bus bar.
