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 TBABH

The electrode/electrolyte interface has a significant impact on the performance of lithium batteries. At the interface, the charged electrode surface, electric double layer (EDL), and solid electrolyte interphase/cathode electrolyte interphase (SEI/CEI) change with voltage, electrolyte, and surface structure. Although...
