Abstract
Electrolyte solutions for flow batteries and other electrochemical systems can contain an active material capable of transferring more than one electron per oxidation-reduction cycle. Such active materials can include coordination compounds containing a metal center and at least one redox non-innocent ligand. Accordingly, flow batteries can include a first half-cell having a first electrolyte solution therein, where the first electrolyte solution contains a coordination compound having at least one redox non-innocent ligand coordinated to a metal center. Particular redox non-innocent ligands can include those bearing a quinone functional group, such as substituted catecholates bearing a quinone functional group. Some active materials can include compositions containing a coordination compound having at least one redox non-innocent ligand coordinated to a metal center, where the at least one redox non-innocent ligand is a substituted catecholate or a salt thereof bearing a quinone functional group.
