The vanadium flow battery (VFB) was first developed in the 1980s. Vanadium is harder than most metals and can be used to make stronger lighter steel, in addition to other industrial uses. It is unusual in that it can exist in four different oxidation states (V2+, V3+, V4+, and V5+), each of which holds a different electrical charge.
