Vanadium redox flow batteries also known simply as Vanadium Redox Batteries (VRB) are secondary (i.e. rechargeable) batteries. VRB are applicable at grid scale and local user level. Focus is here on grid scale applications. VRB are the most common flow batteries.
Traditional vanadium redox flow battery only utilizes redox reactions of V O 2 + / V O 2 + and V O 2 + / V 3. In order to improve its energy density, an all-vanadium redox flow battery with V (IV) as the sole parent active species is developed by accessing the V O 2 + / V 3 + redox couple.
All-vanadium redox flow batteries use V (II), V (III), V (IV), and V (V) species in acidic media. This formulation was pioneered in the late eighties by the research group of Dr Maria Skyllas-Kazacos as an alternative to the Fe/Cr chemistry originally proposed by NASA.
The most commercially developed chemistry for redox flow batteries is the all-vanadium system, which has the advantage of reduced effects of species crossover as it utilizes four stable redox states of vanadium. This chapter reviews the state of the art, challenges, and future outlook for all-vanadium redox flow batteries. 1.
