Stabilizing interface between Li10SnP2S12 and Li metal by molecular layer deposition

Organic-inorganic hybrid interlayer (alucone) is fabricated at the interface between Li10SnP2S12 and Li metal by molecular layer deposition. By virtue of the alucone coating layer, the interfacial reactions between Li10SnP2S12 and Li metal are effectively suppressed. As a result, all-solid-state lithium metal batteries with alucone-coated Li metal exhibit higher specific capacity, smaller polarization, and longer cycle life.140
