Science Daily  July 10, 2023 Redox flow batteries have a unique architecture that potentially enables cost-effective long-duration energy storage to address the intermittency introduced by increased renewable integration for the decarbonization of the electric power sector. Targeted molecular engineering has demonstrated electrochemical reversibility in natively redox-inactive ketone molecules in aqueous electrolytes. However, the kinetics of fluorenone-based flow batteries continue to be limited by slow alcohol oxidation. A team of researchers in the US (Pacific Northwest National Laboratory, Yale University) showed how strategically designed proton regulators can accelerate alcohol oxidation and thus enhance battery kinetics. Fluorenone-based flow batteries with the organic […]
