Decoupled Ion Transport via Triadic Molecular Synergy in Flame‐Retardant Quasi‐Solid Electrolytes for Safe Lithium Metal Batteries

Abstract Ionic liquids (IL)‐based quasi‐solid polymer electrolytes (QSPEs) hold promise for safe lithium metal batteries owing to their tunable electrochemical properties and processability. However, traditional design strategy has ignored the interdependencies among “component‐function‐interface”, leading to compromised practical applications hindered by sluggish lithium‐ion transport kinetics and safety concerns. Herein, a triadic molecular synergy paradigm is proposed to decouple lithium‐ion conduction mechanisms in flame‐retardant QSPEs. Pentaerythritol tetraacrylate‐lithium bis(trifluoromethanesulfonyl)imide (LiTFSI) provides the structural framework, while the IL (1‐butyl‐3‐methylimidazole bis…
