Stacked battery

A stacked battery comprising:

• at least one short-circuit current shunt part;
• and
• a plurality of electric elements,
• the short-circuit current shunt part and the electric elements being stacked,
• wherein:
• the short-circuit current shunt part comprises a first current collector layer, a second current collector layer, and an insulating layer provided between the first and second current collector layers, all of these layers being stacked;
• each electric element comprises a cathode current collector layer, a cathode material layer, an electrolyte layer, an anode material layer, and an anode current collector layer, all of these layers being stacked;
• the first current collector layer is electrically connected to the cathode current collector layer;
• the second current collector layer is electrically connected to the anode current collector layer;
• the electric elements are electrically connected to each other in parallel;
• and
• the short-circuit current shunt part next to the electric elements comprises a PPTC layer between the first current collector layer and the insulating layer and/or between the second current collector layer and the insulating layer.
