In article number 2000279, Maximilian Fichtner, Stefano Passerini, and co‐workers demonstrate improved interfacial properties of a lithium lanthanium zirconate (LLZO) solid‐electrolyte (SE)‐based solid‐state battery by employing ionic liquid interlayers at the electrode/electrolyte junctions. This strategy lowers the interfacial resistances and suppresses Li dendrite formation, thus enabling high Li reversibility with the SE. As a result, cells stacked in bipolar configuration deliver excellent electrochemical performance.
