In Situ Polymerized Polyfluorinated Crosslinked Polyether Electrolytes for High-Voltage Lithium Metal Batteries.

ABSTRACT: In situ polymerized polyether electrolytes are promising for solid-state Li metal batteries due to their high ionic conductivity and excellent interfacial contact. However, their practical application is hindered by Li dendrite formation, interfacial degradation, and limited oxidative stability. Herein, we propose an in situ polymerized polyfluorinated crosslinked polyether electrolyte (PDOL-OFHDBO), synthesized by copolymerizing 1,3-dioxolane (DOL) with 2,2'-(2,2,3,3,4,4,5,5-octafluorohexane-1,6-diyl)bis(oxirane) (OFHDBO) as a polyfluorinated crosslinker. The electron-withdrawing polyfluorinated groups endow PDOL-OFHDBO with enhanced oxidative stability and interfacial compatibility, while reducing the solvation power of the polymer matrix to promote an anion-derived inorganic-rich solid
