Vanadium
Vanadium (The ‘beautiful metal’ that stores energy)
Vanadium is a rare, hard, ductile gray-white element found combined in certain minerals and used mainly to produce certain alloys. Vanadium resists corrosion due to a protective film of oxide on the surface. Common oxidation states of vanadium include +2, +3, +4 and +5.
