Unlocking High‐Voltage and Low‐Temperature Capability in Lithium Metal Batteries via Coupling Bulk Solvation Tailoring with Interfacial Electrostatic “Anchor‐and‐Shield” Strategy
Ether electrolytes in Li‐metal batteries are severely constrained by parasitic anodic oxidation and solvent ring‐opening polymerization (ROP). To overcome this, we propose an “anchor‐and‐shield” strategy using 0.05 M TBABH4 in 1 M LiFSI DME/DOL. Nucleophilic BH4− incorporates into the Li+ solvation shell, neutralizing...
