A cyclic-triphosphazene based single-ion polymer electrolyte prepared via click reaction for lithium metal batteries

Abstract

This study presents a rapid preparation method for a self-supporting polymer electrolyte via thiol–ene click reaction. The resulting electrolyte demonstrates a high ionic conductivity of 9.5 × 10⁻⁴ S cm⁻¹ at 90 °C and a lithium ion transference number of 0.77. The lithium symmetrical battery stably operated for 1200 h at 0.1 mA cm⁻², significantly suppressing the formation of lithium dendrites.
