摘要:
Redox flow battery systems having a supporting solution that contains Cl− ions can exhibit improved performance and characteristics. Furthermore, a supporting solution having mixed SO42− and Cl− ions can provide increased energy density and improved stability and solubility of one or more of the ionic species in the catholyte and/or anolyte. According to one example, a vanadium-based redox flow battery system is characterized by an anolyte having V2+ and V3+ in a supporting solution and a catholyte having V4+ and V5+ in a supporting solution. The supporting solution can contain Cl− ions or a mixture of SO42− and Cl− ions.

摘要:
A redox flow battery having a supporting solution that includes Cl− anions is characterized by an anolyte having V2+ and V3+ in the supporting solution, a catholyte having Fe2+ and Fe3+ in the supporting solution, and a membrane separating the anolyte and the catholyte. The anolyte and catholyte can have V cations and Fe cations, respectively, or the anolyte and catholyte can each contain both V and Fe cations in a mixture. Furthermore, the supporting solution can contain a mixture of SO42− and Cl− anions.

摘要:
Iron-sulfide redox flow battery (RFB) systems can be advantageous for energy storage, particularly when the electrolytes have pH values greater than 6. Such systems can exhibit excellent energy conversion efficiency and stability and can utilize low-cost materials that are relatively safer and more environmentally friendly. One example of an iron-sulfide RFB is characterized by a positive electrolyte that comprises Fe(III) and/or Fe(II) in a positive electrolyte supporting solution, a negative electrolyte that comprises S2− and/or S in a negative electrolyte supporting solution, and a membrane, or a separator, that separates the positive electrolyte and electrode from the negative electrolyte and electrode.
