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 Sand/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.

The present invention provides a material and a method for its creation and use wherein a reactive element, preferably a rare earth element, is included in an oxide coating material. The inclusion of this material modifies the growth and structure of the scale beneath the coating on metal substrate and improves the scale adherence to the metal substrate.
