Two-electron storage electrolytes for aqueous organic redox flow batteries

Abstract

Aqueous organic redox flow batteries (AORFBs) are promising candidates for the large-scale storage of intermittent renewable energy because of their technological advantages of decoupled power and capacity, convenient scale up, diverse organic molecules, potential low cost, and high safety. In this perspective, we focus on the development of two-electron redox molecules, which possess an advanced capacity compared with the one-electron redox molecules typically employed in AORFBs. The great achievements and confronted challenges are discussed and constructive suggestions and opinions are presented.
