摘要： Various embodiments include processes for purifying and/or preparing iron-bearing materials. Various embodiments include purification and/or preparation of iron ores, iron, and their intermediates. Various embodiments include processes for purifying iron-bearing materials comprising leaching one or more soluble species of impurities out of iron-bearing materials using a leaching solution comprising fluorine.

摘要： Systems, methods, and devices of various aspects include using tin, antimony, and/or indium as an additive to an electrolyte and/or electrode in an electrochemical system, such as a battery, having an iron-based anode. In some aspects, the addition of tin, antimony, and/or indium may improve cycling of the iron-based anode. Systems, methods, and devices of various aspects include using high hydroxide concentration electrolyte in an electrochemical system, such as a battery. In some aspects, a high hydroxide concentration electrolyte may increase the stored amount of charge stored in the cell (i.e., the capacity of the battery material) and/or decrease the overpotential (i.e., increase the voltage) of the battery.
