Outside Back Cover: The review of doi:10.1002/idm2.12202 summarizes recent advancements in interface engineering for solid-state lithium metal batteries. As illustrated in the image, an interface layer is between lithium metal and solid-states electrolyte, which should not only play as buffer layer to void the intrinsic solid-solid contact but also severe as fast lithium pathway to uniform lithium deposition. Moreover, future viable interfacial layers should demonstrate exceptional chemical and electrochemical stability, high lithium ion conductivity, and soft yet intimate contact with both lithium and the electrolyte.
