Interfacial nanoarchitectonics for solid-state lithium batteries.

Strong demand for solid-state lithium batteries has prompted intensive research for achieving fast ionic conduction in solids. Although the highest conductivity found among sulfides is higher than that of liquid electrolytes, it improves the battery performance only in combination with electrodes via a low-resistance interface. This Article reviews some interfacial structures that lower the interfacial resistance to enable high-power interfaces by controlling the carrier density.
