Lithium vanadium oxide has been proposed for use as a high energy density anode for lithium-ion batteries, at 745 Wh/L when paired with a lithium cobalt oxide cathode. [96] Vanadium phosphates have been proposed as the cathode in the lithium vanadium phosphate battery , another type of lithium-ion battery.
The vanadium redox battery (VRB), also known as the vanadium flow battery (VFB) ... Precipitation inhibitors can increase the density to about 35 Wh/kg (126 kJ/kg ...

Vanadium(V) oxide (vanadia) is the inorganic compound with the formula V 2 O 5.Commonly known as vanadium pentoxide, it is a dark yellow solid, although when freshly precipitated from aqueous solution, its colour is deep orange.
Vanadium(IV) oxide or vanadium dioxide is an inorganic compound with the formula VO 2.It is a dark blue solid. Vanadium(IV) dioxide is amphoteric, dissolving in non-oxidising acids to give the blue vanadyl ion, [VO] 2+ and in alkali to give the brown [V 4 O 9] 2− ion, or at high pH [VO 4] 4−. [4]
Vanadium carbide is the inorganic compound with the formula V C. It is an extremely hard and refractory ceramic material. With a hardness of 9-9.5 Mohs, it is possibly the hardest metal- carbide known. [ 2 ]
The cell offered more than double the energy density of vanadium-based systems. [64] [65] The major challenge was the lack of a stable catholyte, holding energy densities below 5 Wh/L. Alkaline AORFBs use excess potassium ferrocyanide catholyte because of the stability issue of ferrocyanide in alkaline solutions.
New York: The International Nickel Company, Inc., 1941: 16. — "Values ranging from 21.3 to 21.5 gm/cm 3 at 20 °C have been reported for the density of annealed platinum; the best value being about 21.45 gm/cm 3 at 20 °C." 21.46 g/cm 3 — Rose, T.
