Abstract: A single-ion conducting gel polymer electrolyte includes a fluorine-based compound with 25-40% of its main chain converted to carbon double bonds, and 35-55 wt % of a lithium salt. The polymer ensures anion immobilization, thereby limiting conduction primarily to lithium ions. By including an optional additive such as PEGMEMA in specific weight ratios, the electrolyte achieves both high ionic conductivity and robust film formation. A method for preparing this gel polymer electrolyte involves mixing the fluorine-based compound, lithium salt, and a radical initiator, followed by in-situ crosslinking. The resulting free-standing film exhibits enhanced lithium-metal anode stability, suppressing dendrite formation. Also disclosed is a lithium secondary battery with this gel polymer electrolyte layer positioned between positive and negative electrodes, demonstrating improved cycle life and higher voltage stability disclosure.
