Abstract
Disclosed is a coated sulfide-containing solid electrolyte material, as well as a solid electrolyte thereof, and a solid state battery containing a solid electrolyte thereof. According to aspects of the disclosure, the coating is formed on the surface of a sulfide-containing solid electrolyte material, and includes a compound having a thiol with a long hydrophobic tail, e.g., such as 1-undecanethiol. The coating may provide protection from air and moisture, for instance, under ambient conditions.
Claims21
A solid electrolyte composition comprising:
- a sulfide-containing solid electrolyte material, having a surface;
- and
- an organic coating, wherein the organic coating is formed on the surface of the sulfide-containing solid state electrolyte material, and
- wherein the coating is formed from at least one compound of Chemical Formula 1 or Chemical Formula 2:
- R-A Chemical Formula (1)
- R-A′-R Chemical Formula (2)
- wherein:
- A is a SH group, an isocyanate, an amine, or a leaving group;
- A′ is a —S— moiety or a —S—S— moiety;
- and
- each R is independently a substituted or unsubstituted C3-C20 alkyl group.
(canceled)
A method for making a solid electrolyte, comprising:
- providing a sulfide-containing solid electrolyte, and
- combining the solid electrolyte with at least one compound of Chemical Formula 1 or Chemical Formula 2 to form a coated sulfide-containing solid electrolyte material:
- R-A Chemical Formula (1)
- R-A′-R Chemical Formula (2)
- wherein:
- A is a SH group, an isocyanate, an amine, or a leaving group;
- A′ is a —S—;
- and
- each R is independently a substituted or unsubstituted C3-C20 alkyl group.
