  • Patent number: 10153520
    Abstract: A manufacturing method for an all-solid-state battery includes: producing a laminated battery having both end surfaces in a lamination direction and a side surface by laminating pluralities of collector layers, positive electrode mixture layers, solid electrolyte layers, and negative electrode mixture layers; supplying a liquid resin to only the side surface of the laminated battery; and curing the liquid resin. Producing the laminated battery by protruding at least one layer of the collector layer, the positive electrode mixture layer, the solid electrolyte layer, and the negative electrode mixture layer relative to remaining of the layers to form a protruding layer. Protruding a plurality of protruding layers from the side surface of the battery. Supplying the resin involves supplying the liquid resin to only the side surface of the laminated battery such that the liquid resin penetrates into a clearance between one protruding layer and another protruding layer.
