A Near-room Temperature Solid Composite Electrolyte Enabled by Lithiated Sulfonated Covalent Organic Frameworks

Abstract

A disulfonic acid-functionalized covalent organic framework (COF)—TpPa-(SO3Li)2, was successfully synthesized and incorporated within polymer matrix to construct the solid-state composite electrolyte (SCE). Simultaneously, a LiFePO4//Li full battery with this SCE sustained a reversible discharge capacity of 147.67 mAh/g after 110 stable cycles (30 °C, 0.2 C).
