Anadium Redox Flow Battery, dzina lathunthu la Vanadium REDOX flow battery (VRB), ndi mtundu wa batri la REDOX momwe zinthu zogwira ntchito zimazungulira ngati madzi. Mabatire a Iron-chromium REDOX akhalapo kuyambira m'ma 1960, koma mabatire a vanadium REDOX adaperekedwa mu 1985 ndi Marria Kacos ku yunivesite ya New South Wales ku Australia, ndipo patatha zaka zoposa makumi awiri zafukufuku ndi chitukuko, teknoloji ili pafupi. wa kukhwima. Ku Japan, mabatire amtundu wokhazikika (mosiyana ndi EV) vanadium owongolera malo opangira magetsi komanso kusungirako mphamvu zamphepo akukula mwachangu, ndipo makina osungira mphamvu amphamvu kwambiri a vanadium agwiritsidwa ntchito ndikugulitsidwa.
Mphamvu yamagetsi yabatire ya vanadiumimasungidwa ngati mphamvu yamankhwala mu sulfuric acid electrolyte ya vanadium ions yamitundu yosiyanasiyana ya valence, ndielectrolytic hydraulickupanikizika kumayikidwa mu mulu wa batri ndi mpope wakunja. Pansi pa mphamvu yamakina, mphamvu ya electrolytic hydraulic imayenda m'matanki osiyanasiyana osungira madzi ndi kuzungulira kwa batire yotsekedwa. Proton exchange membrane imagwiritsidwa ntchito ngati diaphragm ya paketi ya batri, ndipo yankho la electrolyte limayenda molingana ndi ma electrode pamwamba ndipo electrochemical reaction imachitika. Mphamvu yamankhwala yomwe imasungidwa mu yankho imasinthidwa kukhala mphamvu yamagetsi posonkhanitsa ndikuyendetsa pakali pano kudzera mu mbale ziwiri za electrode. Njira yosinthira iyi imathandizira kuti batire ya vanadium iperekedwe, kutulutsidwa ndikuchangidwanso bwino. Positive electrolyte imakhala ndi V (Ⅴ) ndi V (Ⅳ) ionic solution, electrolyte negative imakhala ndi V (Ⅲ) ndi V (Ⅱ) ionic solution, kulipiritsa batri, zinthu zabwino za V (Ⅴ) ionic solution, V (Ⅱ) ionic yankho, kutulutsa kwa batri, ma elekitirodi abwino ndi oyipa motsatana kwa V (Ⅳ) ndi V (Ⅲ) yankho la ionic, batri lamkati kudzera mumayendedwe a H +. V(Ⅴ) ndi V(Ⅳ) ma ion alipo mu mawonekedwe a VO2+ ion ndi VO2+ ion motsatana mu yankho la acidic, kotero zabwino ndi zoyipa za mabatire a vanadium zitha kuwonetsedwa motere:
Ma elekitirodi abwino panthawi yochapira: VO2++H2O→VO2++2H+++e-
Elekitirodi yolakwika mukamalipira: V3++ e-→ V2+
Anode yotulutsa: VO2++2H++e-→VO2++H2O
Elekitirodi yotulutsa: V2+→V3++ e-
Imagwiritsidwa ntchito ngati njira yosungira mphamvu,vanadium mabatirekukhala ndi makhalidwe otsatirawa
1, mphamvu yotulutsa batri imadalira kukula kwa mulu wa batri, mphamvu yosungiramo mphamvu yosungiramo mphamvu imadalira kusungirako kwa electrolyte ndi ndende, kotero mapangidwe ake ndi osinthika kwambiri, pamene mphamvu yotulutsa ndi yotsimikizika, kuwonjezera mphamvu yosungirako mphamvu, monga bola kuonjezera voliyumu ya thanki yosungirako electrolyte kapena kusintha ndende electrolyte;
2, chinthu chogwira cha batri ya vanadium chili mumadzimadzi, ion electrolyte ndi imodzi yokhaion vanadium, kotero palibe kusintha kwa gawo la mabatire ena pamene akuyitanitsa ndi kutulutsa, batire ili ndi moyo wautali wautumiki;
3, kulipira, kutulutsa ntchito ndikwabwino, kumatha kutulutsa mozama popanda kuwononga batire;
4. Kudziletsa kwapang'onopang'ono, pamene dongosolo liri mumayendedwe otsekedwa, electrolyte mu thanki ilibe chodzidzimutsa chokha;
5, ufulu wa malo a batri ya vanadium, makinawo amatha kutsekedwa kwathunthu, osaipitsa, kukonza kosavuta, mtengo wotsika mtengo;
6, makina a batri alibe kuphulika kapena ngozi yamoto, chitetezo chachikulu;
7, mbali batire zambiri zotchipa mpweya zipangizo, mapulasitiki uinjiniya, magwero zakuthupi ndi olemera, zosavuta abwezeretse, safuna zitsulo zamtengo wapatali monga electrode chothandizira;
8, mphamvu zamagetsi, mpaka 75% ~ 80%, ntchito yotsika mtengo kwambiri;
9. Kuthamanga kwachangu, ngati riyakitala ili yodzaza ndi electrolyte, ikhoza kuyambika mkati mwa 2min, ndipo kusinthana kwa boma ndi kutulutsa kumangofunika 0.02s panthawi yogwira ntchito.
VET Technology Co., Ltd ndi dipatimenti yamphamvu ya VET Group, yomwe ndi bizinesi yapamwamba kwambiri padziko lonse lapansi yomwe imagwira ntchito pa kafukufuku ndi chitukuko, kupanga, malonda ndi ntchito zamagalimoto ndi mphamvu zatsopano, makamaka zomwe zimagwira pamagalimoto angapo, mapampu a vacuum, mafuta cell&batire yothamanga, ndi zina zatsopano zapamwamba.
Kwa zaka zambiri, tasonkhanitsa gulu la akatswiri odziwa bwino ntchito komanso akatswiri amakampani ndi magulu a R & D, ndipo takhala ndi zokumana nazo zambiri pakupanga zinthu ndi kugwiritsa ntchito uinjiniya. Takhala takwaniritsa zopambana zatsopano pakupanga zida zopangira zinthu zokha komanso kapangidwe ka makina opangira makina, zomwe zimathandiza kampani yathu kukhalabe yampikisano wamphamvu pamakampani omwewo.
Ndi luso la R & D kuchokera ku zida zazikulu mpaka kumaliza ntchito, matekinoloje ofunikira komanso ofunikira paufulu wodziyimira pawokha wazinthu zaluso akwaniritsa zatsopano zingapo zasayansi ndiukadaulo. Chifukwa cha khalidwe lokhazikika lazinthu, ndondomeko yabwino kwambiri yotsika mtengo komanso ntchito yapamwamba pambuyo pogulitsa malonda, tapambana kuzindikira ndi kudalira makasitomala athu.
