The developing of all-solid-state lithium-metal batteries promises to improve safety and energy density. The challenges in the anode|electrolyte interface are crucial and divided into static and dynamic issues in this review. The static issues are mainly shown as the huge resistances appearing in the assembled batteries, while the dynamic issues are reflected in the rapid deterioration of cycling performance. The static issues are mainly due to the poor chemical stability and interfacial contact, while dendrite growth and void formation are contained in the dynamic issues. Solving dynamic issues on the basis of static issues can conduce to the construction of stable all-solid-state lithium-metal batteries.
