Vanadium Redox Flow Battery, tag nrho lub npe Vanadium REDOX ntws roj teeb (VRB), yog ib hom REDOX roj teeb uas muaj cov khoom siv hauv lub xeev ua kua. Iron-chromium REDOX roj teeb tau nyob ib puag ncig txij li xyoo 1960, tab sis vanadium REDOX roj teeb tau npaj rau xyoo 1985 los ntawm Marria Kacos ntawm University of New South Wales hauv Australia, thiab tom qab ntau tshaj li ob xyoo caum ntawm kev tshawb fawb thiab kev loj hlob, thev naus laus zis nyob rau hauv verge. ntawm kev loj hlob. Hauv Nyij Pooj, hom ruaj khov (raws li tsis yog EV) roj teeb vanadium rau lub ncov tswj fais fab chaw nres tsheb thiab cua zog cia tau txhim kho sai, thiab lub zog loj vanadium roj teeb lub zog khaws cia tau muab tso rau hauv kev siv thiab ua lag luam.
Lub zog hluav taws xob ntawmroj teeb vanadiumyog khaws cia li tshuaj zog nyob rau hauv sulfuric acid electrolyte ntawm vanadium ions ntawm txawv valence xeev, thiab covelectrolytic hydraulicsiab yog muab tso rau hauv lub roj teeb pawg los ntawm lwm lub twj tso kua mis. Nyob rau hauv qhov kev txiav txim ntawm txhua yam fais fab, lub electrolytic hydraulic siab circulates nyob rau hauv txawv kua cia tso tsheb hlau luam thiab kaw lub voj ntawm ib nrab roj teeb. Proton pauv daim nyias nyias yog siv los ua lub diaphragm ntawm cov roj teeb pob, thiab cov tshuaj electrolyte ntws mus rau lub electrode nto thiab electrochemical cov tshuaj tiv thaiv tshwm sim. Cov tshuaj siv hluav taws xob khaws cia hauv cov tshuaj yog hloov mus rau hauv hluav taws xob hluav taws xob los ntawm kev sau thiab ua tam sim no los ntawm ob daim hlau electrode. Cov txheej txheem thim rov qab no ua rau lub roj teeb vanadium raug them, tawm thiab rov ua kom zoo dua. Cov electrolyte zoo muaj V(Ⅴ) thiab V(Ⅳ) ionic tov, tsis zoo electrolyte muaj V(Ⅲ) thiab V(Ⅱ) ionic tov, roj teeb them, khoom zoo rau V(Ⅴ) ionic tov, V(Ⅱ) ionic kev daws teeb meem, roj teeb tawm, qhov zoo thiab tsis zoo electrode feem rau V (Ⅳ) thiab V (Ⅲ) ionic tov, lub roj teeb sab hauv los ntawm H + kev coj ua. V (Ⅴ) thiab V (Ⅳ) ions muaj nyob rau hauv daim ntawv ntawm VO2 + ion thiab VO2 + ion feem hauv cov kua qaub, yog li qhov zoo thiab tsis zoo ntawm cov roj teeb vanadium tuaj yeem qhia tau raws li hauv qab no:
Qhov zoo electrode thaum them nyiaj: VO2 ++ H2O → VO2 ++ 2H ++ e-
Tsis zoo electrode thaum them nyiaj: V3++ e-→V2+
Tawm tawm anode: VO2 + 2H ++ e- → VO2 ++ H2O
Tshem tawm tsis zoo electrode: V2 + → V3 ++ e-
Siv raws li lub zog cia system,roj teeb vanadiummuaj cov yam ntxwv hauv qab no
1, lub zog tso zis ntawm lub roj teeb nyob ntawm qhov loj ntawm pawg roj teeb, lub zog cia muaj peev xwm nyob ntawm qhov chaw khaws cov electrolyte thiab concentration, yog li nws cov qauv siv tau yooj yim heev, thaum lub zog tso zis yog qhov tseeb, txhawm rau ua kom lub zog khaws cia muaj peev xwm, yog li nws tsim tau yooj yim heev, thaum lub zog tso zis yog qhov tseeb, kom muaj peev xwm khaws cia lub zog, xws li ntev npaum li qhov ua kom lub ntim ntawm lub tank cia electrolyte los yog txhim kho cov electrolyte concentration;
2, cov khoom nquag ntawm vanadium roj teeb muaj nyob rau hauv cov kua, cov electrolyte ion tsuas yog ib qhovanadium ion, yog li tsis muaj theem hloov pauv ntawm lwm cov roj teeb thaum them thiab tawm, lub roj teeb muaj lub neej ua haujlwm ntev;
3, kev them nqi, kev ua haujlwm tawm yog qhov zoo, tuaj yeem sib sib zog nqus tawm yam tsis muaj kev puas tsuaj rau lub roj teeb;
4. Tsawg tus kheej tawm, thaum lub kaw lus kaw, cov electrolyte hauv lub tank tsis muaj qhov tshwm sim ntawm tus kheej;
5, vanadium roj teeb qhov chaw muaj kev ywj pheej, lub kaw lus tuaj yeem ua haujlwm tsis siv neeg kaw, tsis muaj kuab paug, kev saib xyuas yooj yim, kev ua haujlwm qis;
6, lub roj teeb system tsis muaj peev xwm tawg lossis hluav taws kub, kev nyab xeeb siab;
7, cov khoom siv roj teeb feem ntau pheej yig carbon cov ntaub ntawv, engineering plastics, cov khoom siv yog nplua nuj, yooj yim rau recycle, tsis xav tau cov khoom muaj txiaj ntsig zoo li electrode catalyst;
8, siab zog efficiency, mus txog 75% ~ 80%, tus nqi siab heev;
9. Kev pib ceev ceev, yog tias lub reactor muaj tag nrho cov electrolyte, nws tuaj yeem pib tsis pub dhau 2min, thiab lub zog them thiab tshem tawm lub xeev hloov tsuas yog xav tau 0.02s thaum lub sijhawm ua haujlwm.
