A near-room temperature solid composite electrolyte enabled by lithiated sulfonated covalent organic frameworks

Abstract

In this study, a disulfonic acid-functionalized covalent organic framework (COF), designated as TpPa-(SO₃Li)₂, was successfully synthesized. Subsequently, this COF was incorporated within a polymer matrix to construct a solid-state composite electrolyte (SCE). Various physical and chemical characterization studies and different electrochemical tests were conducted.
