Abstract

See full text

Interfacial films, which are both electronic conducting and ion conducting, for anode films are provided. The one or more protective films described herein may be mixed conduction materials, which are both electronic conducting and ion-conducting. The one or more protective films described herein may include materials selected from lithium transition metal dichalcogenides, Li9Ti5O12, or a combination thereof. The lithium transition metal dichalcogenide includes a transition metal dichalcogenide having the formula MX2, wherein M is selected from Ti, Mo, or W and X is selected from S, Se, or Te. The transition metal dichalcogenide may be selected from TiS2, MoS2, WS2, or a combination thereof. The lithium transition metal dichalcogenide may be selected from lithium-titanium-disulfide (e.g., LiTiS2), lithium-tungsten-disulfide (e.g., LiWS2), lithium-molybdenum-disulfide (e.g., LiMoS2), or a combination thereof.
