➀ Researchers at the Chinese Dalian Institute of Chemical Physics have developed air-stable organic redox compounds for aqueous flow batteries using naphthalene derivatives with active hydroxyls and dimethylamine scaffolds. ➁ These materials demonstrated stability through 850 cycles at 50Ah/litre and could operate smoothly for approximately 600 cycles under continuous air flow. ➂ The synthesis method is scalable, with pilot-scale battery stacks achieving remarkable cycling stability over 270 cycles with high capacity retention.
