CATHODES CAPABLE OF OPERATING IN AN ELECTROCHEMICAL REACTION, AND RELATED CELLS, DEVICES, AND METHODS

摘要

A flow battery is described, including a catholyte in the form of an aqueous solution of at least one salt of a halogen oxoacid compound; and an anolyte that includes an eletrochemically-active material capable of participating in a reduction-oxidation (redox) reaction with the catholyte salt; along with an intervening ion-permeable membrane. A unique cathode used in the battery or for other purposes is also described, along with a method of providing electrical energy to a device, system, or vehicle, using the flow battery.

1. A flow battery, comprising:
a catholyte first chamber comprising an aqeuous solution of at least one salt of a halogen oxoacid; an anolyte second chamber comprising an aqeuous solution of an electrochemically active material that is capable of participating in a reduction-oxidation reaction with the at least one salt of the halogen oxoacid; at least one ion-permeable membrane separating the first chamber and the second chamber; and means for flowing the aqueous solutions through the battery.
