Vanadium Redox Flow Roj Teeb, lub npe tag nrho Vanadium REDOX flow battery (VRB), yog ib hom REDOX roj teeb uas cov khoom siv nquag ncig hauv cov kua. Cov roj teeb hlau-chromium REDOX tau muaj txij li xyoo 1960, tab sis cov roj teeb vanadium REDOX tau raug thov los ntawm Marria Kacos hauv xyoo 1985 ntawm University of New South Wales hauv Australia, thiab tom qab ntau tshaj ob xyoo caum ntawm kev tshawb fawb thiab kev txhim kho, cov thev naus laus zis tab tom yuav loj hlob. Hauv Nyiv Pooj, cov roj teeb vanadium hom ruaj khov (piv rau EV) rau cov chaw nres tsheb fais fab siab tshaj plaws thiab kev khaws cia lub zog cua tau tsim kho sai, thiab cov roj teeb vanadium muaj zog siab tau muab tso rau hauv kev siv thiab kev lag luam.
Lub zog hluav taws xob ntawmroj teeb vanadiumyog khaws cia ua lub zog tshuaj lom neeg hauv sulfuric acid electrolyte ntawm vanadium ions ntawm ntau lub xeev valence, thiabelectrolytic hydraulicLub zog raug muab tso rau hauv lub roj teeb los ntawm lub twj tso kua sab nraud. Nyob rau hauv qhov kev ua ntawm lub zog kho tshuab, lub zog hydraulic electrolytic ncig hauv cov thoob dej sib txawv thiab lub voj voog kaw ntawm ib nrab roj teeb. Proton pauv daim nyias nyias yog siv ua lub diaphragm ntawm lub roj teeb pob, thiab cov kua electrolyte ntws sib luag rau ntawm qhov chaw electrode thiab cov tshuaj electrochemical tshwm sim. Lub zog tshuaj lom neeg khaws cia hauv cov tshuaj raug hloov mus ua lub zog hluav taws xob los ntawm kev sau thiab coj tam sim no los ntawm ob lub phaj electrode. Cov txheej txheem tshuaj tiv thaiv rov qab no ua rau lub roj teeb vanadium raug them, tso tawm thiab rov them dua zoo. Cov electrolyte zoo muaj cov kua ionic V (Ⅴ) thiab V (Ⅳ), cov electrolyte tsis zoo muaj cov kua ionic V (Ⅲ) thiab V (Ⅱ), kev them roj teeb, cov khoom zoo rau V (Ⅴ) kua ionic, V (Ⅱ) kua ionic, kev tso tawm roj teeb, cov electrode zoo thiab tsis zoo rau V (Ⅳ) thiab V (Ⅲ) kua ionic, lub roj teeb sab hauv los ntawm H + conduction. V(Ⅴ) thiab V(Ⅳ) ions muaj nyob rau hauv daim ntawv ntawm VO2+ ion thiab VO2+ ion feem ntau hauv cov kua qaub, yog li cov tshuaj tiv thaiv zoo thiab tsis zoo ntawm cov roj teeb vanadium tuaj yeem qhia tau raws li hauv qab no:
Lub electrode zoo thaum lub sijhawm them: VO2 ++ H2O → VO2 ++ 2H ++ e-
Cov electrode tsis zoo thaum them: V3++ e-→V2+
Cov anode tawm: VO2 ++ 2H ++ e- → VO2 ++ H2O
Tso tawm cov electrode tsis zoo: V2 + → V3 ++ e-
Siv ua lub zog cia khoom,roj teeb vanadiummuaj cov yam ntxwv hauv qab no
1, lub zog tso zis ntawm lub roj teeb nyob ntawm qhov loj ntawm lub roj teeb pawg, lub peev xwm khaws cia lub zog nyob ntawm qhov cia electrolyte thiab concentration, yog li nws tus qauv tsim yog qhov yooj ywm heev, thaum lub zog tso zis yog qhov tseeb, kom nce lub peev xwm khaws cia lub zog, tsuav yog nce qhov ntim ntawm lub tank cia electrolyte lossis txhim kho qhov electrolyte concentration;
2, cov khoom siv nquag ntawm vanadium roj teeb muaj nyob rau hauv cov kua, cov electrolyte ion tsuas yog ib qho xwbvanadium ion, yog li ntawd tsis muaj kev hloov pauv theem ntawm lwm lub roj teeb thaum them thiab tso tawm, lub roj teeb muaj lub neej ua haujlwm ntev;
3, kev them nqi, kev tso tawm zoo, tuaj yeem tso tawm tob yam tsis ua rau lub roj teeb puas tsuaj;
4. Kev tso tawm tus kheej tsawg, thaum lub kaw lus kaw, cov electrolyte hauv lub tank tsis muaj qhov tshwm sim ntawm kev tso tawm tus kheej;
5, vanadium roj teeb qhov chaw ywj pheej, lub kaw lus tuaj yeem ua haujlwm kaw tag nrho, tsis muaj kuab paug, yooj yim txij nkawm, tus nqi ua haujlwm tsawg;
6, lub roj teeb tsis muaj kev phom sij rau kev tawg lossis hluav taws, kev nyab xeeb siab;
7, cov khoom siv roj teeb feem ntau yog cov khoom siv carbon pheej yig, cov yas engineering, cov khoom siv nplua nuj, yooj yim rov ua dua tshiab, tsis xav tau cov hlau muaj nqis ua cov catalyst electrode;
8, kev siv hluav taws xob zoo, txog li 75% ~ 80%, kev ua haujlwm siab heev;
9. Kev pib ceev ceev, yog tias lub reactor puv nrog electrolyte, nws tuaj yeem pib ua haujlwm hauv 2 feeb, thiab lub xeev them thiab tso tawm tsuas yog xav tau 0.02s thaum lub sijhawm ua haujlwm.
