Solid-state laminate electrode assemblies and methods of making

Abstract

Solid-state laminate electrode assemblies and various methods for making the solid-state laminate electrode assemblies involve a lithium metal layer reactively bonded to a lithium ion conducting sulfide glass layer. During manufacture, highly reactive surfaces of the lithium metal layer and the lithium ion conducting sulfide glass layer are maintained in its substantially unpassivated state until they have been reactively bonded.

1 - 14 . (canceled) 
     
     
         15 . A lithium metal laminate structure, the laminate comprising:
 i) a lithium metal layer having a first and second major surface, wherein the first major surface is substantially unpassivated; and   ii) a protective material layer that removably covers and protects the lithium first major surface in direct contact.   
     
     
         16 . The lithium metal laminate structure of  claim 15 , wherein the substantially unpassivated lithium metal surface is stable. 
     
     
         17 . The lithium metal laminate structure of  claim 15 , wherein the protective material layer is a liquid phase super dry hydrocarbon liquid. 
     
     
         18 . An inorganic solid electrolyte laminate structure, the laminate comprising:
 i) a lithium ion conducting sulfide glass layer having a first and second major surface; and   ii) a protective material layer that removably covers and protects the sulfide glass first major surface.   
     
     
         19 . The solid electrolyte laminate structure of  claim 18 , wherein the protective material layer is a super dry liquid phase hydrocarbon liquid.
