A Multifunctional Potent Lewis Acid for In Situ Formation of Poly-Dioxolane Electrolytes Toward High-Performance Quasi-Solid State Lithium Metal Batteries.

ABSTRACT: Quasi-solid-state polymer electrolytes represent a promising strategy for Li metal batteries (LMBs) with superior safety and energy density. However, Li dendrite formation and unstable interfaces significantly hinder their practical application. Here, an AlCl₃-initiated gel polymer electrolyte (AGPE) is developed via in situ ring-opening polymerization of 1,3-dioxolane (DOL) to directly generate poly(1,3-dioxolane) (PDOL) electrolyte in battery cells. AlCl₃ acts both as polymerization initiator and a multifunctional additive, enhancing polymer network stability and facilitating selective Li⁺ transport through an AlCl₃-mediated multi-coordination framework. Additionally, AlCl₃ spontaneously generates a hybrid SEI layer composed of LiF,
