1. 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.
