Dual Anion‐Involved Interfacial Chemistry Enables Ultra‐Stable PEO‐Based Solid‐State Lithium Metal Batteries by Suppressing NMP‐Induced Side Reactions
The incorporation of solvent N‐methylpyrrolidone (NMP) into polyethylene oxide (PEO) weakens EO‐Li + interaction and boosts Li + transport via strong Li + affinity, but free NMP inevitably reacts with Li metal, undermining interface stability. Herein, we report a dual‐anion coordination strategy that repurpos...
