By Richard Spencer, President & CEO, U3O8 Corp. Vanadium is a peculiar metal in that it naturally exists in no less than four different charge states, which makes it ideal as a battery metal. It''s main use however is in steel – adding just one kilogram of vanadium to a tonne of steel doubles the strength of the steel.
Factors limiting the uptake of all-vanadium (and other) redox flow batteries include a comparatively high overall internal costs of $217 kW −1 h −1 and the high cost of stored electricity of ≈ $0.10 kW −1 h −1.

Vanadium belongs to the VB group elements and has a valence electron structure of 3 d 3 s 2. It can form ions with four different valence states (V 2+, V 3+, V 4+, and V 5+) that have active chemical properties. Valence pairs can be formed in acidic medium as V 5+ /V 4+ and V 3+ /V 2+, where the potential difference between the pairs is
