Technical FAQs 4

What are aqueous organic redox flow batteries?

Recently, aqueous organic redox flow batteries (AORFBs), utilizing water-soluble organic molecules as redox-active species, have garnered widespread attention [8, 9]. The conversion between electrical and chemical energy in organic molecules often involves electron transfer at active centers such as oxygen, nitrogen, sulfur, or radicals, etc.

Are redox flow batteries a cost-effective energy storage device?

Redox flow batteries using aqueous organic-based electrolytes are promising candidates for developing cost-effective grid-scale energy storage devices. However, a significant drawback of these batteries is the cross-mixing of active species through the membrane, which causes battery performance degradation.

Can organic redox-active materials be used for Advanced Flow batteries?

Organic redox-active materials offer a new opportunity for the construction of advanced flow batteries due to their advantages of potentially low cost, extensive structural diversity, tunable electrochemical properties, and high natural abundance.

What is interaction-mediating strategy for aqueous redox flow batteries?

An “interaction-mediating” strategy towards enhanced solubility and redox properties of organics for aqueous flow batteries. Nano Energy 69, 104464 (2020).
