Patent ID: 10651456

Abstract:
In an all-solid-state battery including at least one short-circuit current shunt part and at least one electric element which are stacked, when the battery is constrained, cracking etc. of the adhesive in the short-circuit current shunt pail is prevented.The all-solid-state battery includes at least one short-circuit current shunt part and at least one electric element which are stacked, to the all-solid-state battery constraint pressure being applied by a constraining member in a direction of stacking the short-circuit current shunt part and the electric element, wherein the short-circuit current shunt part includes 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 along the direction, to be adhered to each other with adhesive, the electric element includes a cathode current collector layer, a cathode material layer, a solid electrolyte layer, an anode material layer, and an anode current collector layer, all of these layers being stacked along the direction, 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, and the adhesive is provided for a zone in the short-circuit current shunt part, to the zone the constraint pressure from the constraining member not being applied.
