Abstract
Batteries made from organic redox polymers represent a promising and viable solution to many issues, particularly in the production of next-generation flexible energy storage systems.(1-4) Nitroxide radical polymers (NRPs) are among the most promising redox polymers available, providing corresponding batteries with high voltage, fast charging, and long cyclability. Despite the attractive properties of NRPs as active electrode materials, these polymers have limited implementation in battery-powered electronic devices or large-scale energy storage. One of the greatest challenges is their low energy storage capability (i.e., 110 mAh/g). For example, most studies on radical polymer batteries could only realize the oxidation process (i.e., TEMPO+/•) for battery applications due to the sluggish kinetics of the reduction process (i.e., TEMPO•/-), which greatly compromises their energy storage capability. Recent research suggests that two-electron storage may be achieved by carefully designing polymer structures, polymer/nanocarbon composites, or electrolytes.(4-6) In recent years, our group has explored how polymer chemical structures and electrode composite morphologies govern the electrochemical properties of the NRP cathode, suggesting that rational design of radical polymer electrodes could enhance energy storage performance.(7-8)
