1. A solid-state battery structure comprising:

  • a plurality of solid-state thin-film battery sub-sheets vertically stacked one atop the other, wherein each solid-state thin-film battery sub-sheet of the plurality of solid-state thin-film battery sub-sheets consists of a substrate portion and a solid-state thin-film battery structure portion wherein each solid-state thin-film battery structure portion comprises a bottom electrode, a cathode, a solid-state electrolyte, and a top electrode, and each substrate portion is composed of a semiconductor material having semiconducting properties, wherein each substrate portion entirely separates the top electrode of a bottom solid-state thin-film battery structure portion from a bottom electrode of a top solid-state thin-film battery structure portion, wherein an entirety of each solid-state thin-film battery structure portion including the bottom electrode, the cathode, the solid-state electrolyte and the top electrode has outermost sidewall surfaces that are vertically aligned to each other and to outermost sidewall surfaces of each of the substrate portions; and

    a plurality of fuse elements located in adjacent to the plurality of solid-state thin-film battery sub-sheets, wherein the bottom electrode of each solid-state thin-film battery sub-sheet of the plurality of solid-state thin-film battery sub-sheets is in electrically communication with one of the plurality of fuse elements, and the fuse elements of the plurality of fuse elements are configured to be in parallel with one another.
