Stacked battery

Abstract

A short-circuit current shunt part does not cause any short circuit during normal battery use, causes stable short circuits in nail penetration, and suppresses sudden temperature rise after nail penetration. A stacked battery includes at least one short-circuit current shunt part including first and second current collector layers, and an insulating layer between the first and second current collector layers, and electric elements each including a cathode current collector layer, a cathode material layer, an electrolyte layer, an anode material layer, and an anode current collector layer, with all layers being stacked. The first current collector layer is electrically connected with the cathode current collector layer, the second current collector layer is electrically connected with the anode current collector layer, the electric elements are electrically connected to each other in parallel, and the short-circuit current shunt part insulating layer formed of a thermosetting resin sheet.
