The interface plays a critical role in the electrochemical performance of batteries. In their Communication (DOI: 10.1002/anie.201908874), J.‐Q. Huang and co‐workers describe the interfacial behavior of the quasi‐solid‐state electrolyte layer Li3OCl with a three‐electrode setup. The electrolyte interface can remarkably reduce the over‐potential of the lithium anode and inhibit solvent decomposition, significantly extending the service life of high‐voltage (4.5 V) lithium metal batteries.
