Title: Interfacial layers for solid-state batteries and methods of making same

Abstract

One or more interfacial layers in contact with a solid-state electrolyte and hybrid electrolyte materials. Interfacial layers comprise inorganic (e.g., metal oxides and soft inorganic materials) or organic materials (e.g., polymer materials, gel materials and ion-conducting liquids). The interfacial layers can improve the electrical properties (e.g., reduce the impedance) of an interface between an a cathode and/or anode and a solid-state electrolyte. The interfacial layers can be used in, for example, solid-state batteries (e.g., solid-state, ion-conducting batteries).
