In article number 2003520, Kyungwon Kwak, Kyung‐Koo Lee and co‐workers design a concentrated bisalt electrolyte for lithium metal batteries. The combination of two different salts (LiDFP and LiTFSI) with vastly different ionic interactions induces preferential interactions between Li + and anions. The presence of the resulting solvation structures not only provides excellent electrochemical performance, but also alleviates issues regarding low ionic conductivity and high viscosity in concentrated non‐aqueous electrolytes.
