Patent ID: 11417911

Abstract:
The invention provides a laminated all-solid-state battery that can increase volumetric energy density and maintain the shape of the all-solid-state battery, as well as a method for producing the laminated all-solid-state battery. The all-solid-state battery comprises a battery stack having two or more unit cells and an exterior film sealing the battery stack, wherein the battery stack has a hexahedron shape formed by a top surface and bottom surface in the stacking direction and first, second, third and fourth side walls, the exterior film is a single film covering the battery stack from the top surface and bottom surface in a manner covering the fourth side wall, and condition (i) is satisfied when collector tabs protrude from the first or third side wall or condition (ii) is satisfied when collector tabs protrude from the second side wall, as well as a method for producing the all-solid-state battery.
