The presentation will cover my group research efforts in developing high performance aqueous organic redox flow batteries (AORFBs) aiming for sustainable and economical large-scale energy storage from solar and wind. We have pioneered the development of novel AORFBs employing water-soluble redox active molecules including viologen, ferrocene, and TEMPO.[1-4] Particularly, the chemistry and battery performance of the FcNCl/MV AORFB will be discussed in detail,[1] where FcNCl is (ferrocenylmethyl)trimethylammonium chloride and MVis methyl viologen dichloride. Challenges and advances in developing AORFBs for practical applications will be discussed. How chemistry plays crucial roles in developing the new generations of redox flow batteries will be emphasized.
