A two-dimensional silicon-containing organic framework facilitates lithium-ion migration in solid-state polymer electrolytes†

Abstract

A two-dimensional silicon-containing organic framework (2D SiOF) is proposed to enhance the lithium-ion migration of poly(ethylene oxide) (PEO) solid-state polymer electrolytes (SPEs). SiOF-modified PEO (SiOF/PEO) SPE shows an increased transference number (0.57). The assembled Li|SiOF/PEO|LiFePO₄ full cells exhibit superior rate and cycling performance.
