A solid electrolyte material comprises Li, T, X and A wherein T is at least one of P, As, Si, Ge, Al, and B; X is one or more halogens or N; A is one or more of S and Se. The solid electrolyte material has peaks at 17.8°±0.75° and 19.2°±0.75° in X-ray diffraction measurement with Cu-Kα(1,2)=1.5418 Å and may include glass ceramic and/or mixed crystalline phases.

Solid electrolyte material and solid-state battery made therewith

A solid electrolyte material comprises Li, T, X and A wherein T is at least one of P, As, Si, Ge, Al, and B; X is one or more halogens or N; A is one or more of S and Se. The solid electrolyte material has peaks at 17.8&#xb0;&#xb1;0.75&#xb0; and 19.2&#xb0;&#xb1;0.75&#xb0; in X-ray diffraction measurement with Cu-K&#x3b1;(1,2)=1.5418 &#x212b; and may include glass ceramic and/or mixed crystalline phases.

Described herein are various embodiments of binder and slurry compositions and methods of making a solid-state battery therefrom. An solid-state electrochemical cell may include a first electrode substrate with a separator layer that is continuously interleaved in an alternating pattern with a second electrode substrate. A method of making a solid-state electrochemical cell may include applying a separator layer to a first electrode substrate and continuously interleaving folded portions of the first electrode substrate with alternating folded portions of a second electrode substrate to form an electrochemical cell.
