Le vanadium-vanadium redox flow maa (VRB)sa tele lava ina paeonia e M. Skyllas-Kazacos ma ē na faigaluega faatasi i le 1983 i le Iunivesite o New South Wales, Ausetalia. O lo'o fa'atupuina nei le tekonolosi e le tele o fa'alapotopotoga e aofia ai le E-Fuel Technology Ltd i Peretania ma le VRB Power Systems Inc. i Kanata. O se vaega faapitoa o le VRB o loʻo faʻaaogaina le elemene kemisi tutusa i le luaanode ma le cathode electrolytes. O le VRB o loʻo faʻaaogaina tulaga faʻamaʻi e fa o le vanadium, ma o le mea sili e tasi le lua redox o le vanadium i totonu o afa-cell taʻitasi. O ulugalii V(II)–(III) ma le V(IV)–(V) e fa'aaogaina i le afa-selau leaga ma le lelei, i le faasologa. E masani lava, o le electrolyte lagolago o le sulfuric acid (∼2-4 mol dm−3) ma le vanadium concentration o loʻo i le va o le 1-2 mol dm-3.

O le fa'aoso-fa'a'ave'esea i le VRB o lo'o fa'aalia i tali [I]-[III]. I le taimi o le faʻagaioiga, o le eletise tatala e masani lava 1.4 V ile 50% state-of-charge ma 1.6 V ile 100% state-of-charge. O eletise faʻaaogaina i VRB e masani lavakaponi lagonapo'o isi fo'i porous, tolu-dimensional kaponi. O ma'a e maualalo le malosi na fa'aogaina ai le kaponi-polymer composite electrodes.

O se fa'amanuiaga tele o le VRB o le fa'aogaina lea o le elemene tutusa i le afa-selau e lua e fesoasoani e aloese ai mai fa'afitauli e feso'ota'i ma le fa'afefe o le lua afa-cell electrolytes a'o fa'aoga umi. Ole electrolyte e umi lona olaga ma faʻaitiitia ai faʻafitauli o le lafoai. O le VRB foi e ofoina atu le maualuga o le malosi (<90% i faʻapipiʻi tetele), tau maualalo mo gafatia tele e teu ai, faʻaleleia o faiga o loʻo i ai, ma le umi o le taamilosaga ola. Fa'agata fa'agata e aofia ai le tau maualuga tele o vanadium fa'avae eletise fa'atasi ma le tau ma le fa'atapula'aina o le ola o le ion-exchange membrane.
