Abstract
Methods for making solid-state laminate electrode assemblies include methods of forming a solid electrolyte interphase (SEI) by ion implanting nitrogen and/or phosphorous into the glass surface by ion implantation.
Claims12
A solid-state laminate electrode assembly, comprising:
- a lithium ion conducting sulfide glass substrate, the substrate comprising a sulfide glass solid electrolyte sheet having room temperature Li ion conductivity of at least 10−5 S/cm, the sulfide glass substrate having first and second major surfaces;
- a solid electrolyte interphase (SEI) layer comprising lithium and one or both of nitrogen and phosphorous at the first major surface of the sulfide glass substrate.
