Quinones having high capacity retention for use as electrolytes in aqueous redox flow batteries
Patent
·
OSTI ID:2222104
We disclose quinone compounds and related species (Formula I) that possess significant advantages when used as a redox active material in a battery, e.g., a redox flow battery. In particular, the compounds provide redox flow batteries (RFBs) with extremely high capacity retention. For example, RFBs of the invention can be cycled for 500 times with negligible loss of capacity, and such batteries could be employed for years of service. Thus, the invention provides a high efficiency, long cycle life redox flow battery with reasonable power cost, low energy cost, and all the energy scaling advantages of a flow battery.
