Regulating Non‐Equilibrium Solvation Structure in Locally Concentrated Ionic Liquid Electrolytes for Wide‐Temperature and High‐Voltage Lithium Metal Batteries

The development of high-voltage lithium metal batteries (LMBs) encounters significant challenges due to aggressive electrode chemistry. Recently, locally concentrated ionic liquid electrolytes (LCILEs) have garnered attention for their exceptional stability with both Li anodes and high-voltage cathodes. However, there remains a limited understanding of how diluents in LCILEs affect the thermodynamic stability of the solvation structure and transportation dynamics of Li
