Vanadium ahụ -batrị vanadium redox flow (VRB)M. Skyllas-Kazacos na ndị ọrụ ibe ya malitere ọrụ ahụ n'afọ 1983 na Mahadum New South Wales, Australia. Ọtụtụ òtù dị iche iche gụnyere E-Fuel Technology Ltd na United Kingdom na VRB Power Systems Inc. na Canada na-emepụta teknụzụ a ugbu a. Otu ihe pụrụ iche nke VRB bụ na ọ na-eji otu ihe kemịkalụ ahụ eme ihe n'ime maanode na electrolytes kathodeVRB na-eji ọnọdụ oxidation anọ nke vanadium, ọ kacha mma inwe otu redox di na nwunye nke vanadium na ọkara sel ọ bụla. A na-eji di na nwunye V(II)–(III) na V(IV)–(V) na ọkara sel na-adịghị mma na nke dị mma, n'otu n'otu. Dịka ọ na-adịkarị, electrolyte na-akwado ya bụ sulfuric acid (∼2–4 mol dm−3) na njupụta vanadium dị n'etiti 1–2 mol dm−3.
A na-egosi mmeghachi omume chajị-mwụpụ na VRB na mmeghachi omume [I]–[III]. N'oge ọrụ, voltaji sekit mepere emepe na-abụkarị 1.4 V na steeti chajị 50% na 1.6 V na steeti chajị 100%. Elektrọd eji na VRBs na-abụkarịihe mkpuchi carbonma ọ bụ ụdị carbon ndị ọzọ nwere oghere, nke nwere akụkụ atọ. Batrị ndị nwere ike dị ala ejirila elektrọd carbon-polymer mee ihe.
Uru dị ukwuu nke VRB bụ na iji otu ihe ahụ eme ihe n'ime ọkara sel abụọ ahụ na-enyere aka izere nsogbu ndị metụtara mmetọ nke ọkara sel abụọ electrolytes n'oge ojiji ogologo oge. Elektrọji ahụ nwere ndụ ogologo oge ma a na-ebelata nsogbu mkpofu ihe mkpofu. VRB na-enyekwa arụmọrụ ike dị elu (<90% na nnukwu nrụnye), ọnụ ala maka ikike nchekwa buru ibu, mmelite nke sistemụ ndị dị adị, na ndụ ogologo oge. Mmachi ndị nwere ike ịgụnye ọnụ ahịa isi obodo dị elu nke electrolytes dabere na vanadium yana ọnụ ahịa na ndụ pere mpe nke membrane mgbanwe ion.
