Abstract
A solid electrolyte material comprising Li, T, X and A wherein T is at least one of P, As, Si, Ge, Al, and B; X is BH4; A is S, Se, or N. The solid electrolyte material may include glass ceramic and/or mixed crystalline phases, and exhibits high ionic conductivity and compatibility with high voltage cathodes and lithium metal anodes.
Claims12
An Argyrodite-type solid electrolyte material comprising:
- Li, T, X and A wherein T is at least one element selected from the group consisting of P, As, Si, Ge, Al, and B;
- X is one or more halogens or BH4, BF4, NH2, or NO3 or a blend thereof;
- A is one or more of S, Se, and N;
- and the solid electrolyte material has peaks at 2θ=14.6°±0.25°, 15.3°±0.25°, and 25.1°±0.25° in X-ray diffraction measurement with Cu-Kα(1,2)=1.5418 Å.
