Abstract
To suppress heat generation in a stacked battery including a plurality of electric elements in internal short circuits and an unstable reaction when the battery is operated while an energy level is increased, the stacked battery includes a stack comprising a first current collector layer, a second current collector layer, a plurality of bipolar current collector layers that are arranged between the first and second current collector layers at intervals in the stacking direction, a plurality of electric elements, an anode active material layer, and an electrolyte layer that is arranged between the cathode and anode active material layers, where the ratio h/S (cm) of a length h (cm) between the one end face and the other end face in the stacking direction of the stack to an electrode area S (cm) on a cross section orthogonal to the stacking direction of the stack is more than 1.
