Abstract: Battery component structures and manufacturing methods for solid-state battery cells include a unitary Li ion conducting sulfide glass solid electrolyte structure that serves as the basic building block around which a solid-state battery cell can be fabricated. The unitary glass structure approach can leverage precision controlled high throughput processes from the semiconductor industry that have been inventively modified as disclosed herein for processing a sulfide glass solid electrolyte substrate into a unitary Li ion conducting glass structure, for example, by using etching and lithographic photoresist formulations and methods. The glass substrate may be precision engineered to effectuate a dense glass portion and a porous glass portion that can be characterized as sublayers having predetermined thicknesses. The porous glass sublayer includes a plurality of discrete substantially vertical closed-end holes or trenches that are precision engineered into one or both major substrate surfaces using microfabrication processes.

Abstract: A solid state battery includes an electrode laminate including an intermediate layer, a first solid electrolyte layer, a positive electrode, and a second solid electrolyte layer sequentially laminated on a negative electrode. The positive electrode includes a positive electrode tab extending therefrom. One of the first solid electrolyte layer or the second solid electrolyte layer includes a porous substrate. One other of the first solid electrolyte layer or the second solid electrolyte layer does not include a porous substrate. When the electrode laminate is viewed from above, outer peripheral ends of the first solid electrolyte layer and the second solid electrolyte layer are located outside an outer peripheral end of the positive electrode, and the first solid electrolyte layer and the second solid electrolyte layer are bonded to each other in a region not opposed to the positive electrode and the positive electrode tab.
