Abstract

A novel kind of solid-state lithium electrolyte was fabricated by impregnating organic ionic plastic crystals (OIPCs) into the pores of covalent organic frameworks (COFs). The liquid-like phase of confined N,N-dimethylpyrrolidinium iodide (P_1,1 I) and the ordered nanochannels of COFs simultaneously stimulated the lithium ion conduction.

Keywords: covalent organic frameworks; lithium ions; organic ionic plastic crystals; solid-state electrolytes.
