Designing organic pseudocapacitors through molecular hybridization

Abstract

In this issue of Joule, Dincă and co-workers showcase a fused aromatic organic electrode material that exhibits remarkable physicochemical properties, such as high electrical conductivity, rapid ion transport, and insolubility in the electrolyte. As a result, the material functions as an excellent pseudocapacitive material that can efficiently store and discharge energy in a short period of time.

High-rate, high-capacity electrochemical energy storage in hydrogen-bonded fused aromaticsChen et al.JouleApril 17, 2023In BriefShortening the charging time for electrochemical energy storage devices, while maintaining their storage capacities, is a major scientific and technological challenge in broader market adoption of such devices. Fused aromatic molecules with abundant redox-active heteroatoms, extended conjugation, and intermolecular hydrogen bonding serve as electrode materials that enable high-rate, high-capacity charge storage. The structural and compositional principles underlining their electrochemical performance provide important blueprints toward the use of organic pseudocapacitive materials in practical, high-rate, high-capacity electrochemical energy storage devices.
