Unique redox-active phenothiazine combinations with depressed melting points for increased solubility and method of use in energy storage and in redox flow batteries

摘要

A combination of redox active compounds is useful in connection with a rechargeable battery and includes a first redox active compound having a first solubility, and a second redox active compound having a second solubility, wherein the combination has a third solubility that is greater than one or both of the first solubility and the second solubility.
