1. A redox flow battery comprising:
a first aqueous electrolyte comprising a first type of redox active material;
a second aqueous electrolyte comprising a second type of redox active material;
wherein the first type of redox active material comprises a quinoxaline moiety, a salt of the quinoxaline moiety, or a mixture thereof;
wherein the quinoxaline moiety is selected from the group consisting of a quinoxaline dimer, a quinoxaline trimer, a quinoxaline tetramer, a quinoxaline polymer, and a quinoxaline dendrimer, or a combination thereof.
