Pūhiko Rere Vanadium Redox, ingoa katoa ko te pākahiko rere Vanadium REDOX (VRB), he momo pākahiko REDOX e rere ana ngā matū hohe i roto i te āhua wai. Kua noho ngā pākahiko REDOX rino-chromium mai i te tekau tau atu i 1960, engari i whakaarohia ngā pākahiko vanadium REDOX i te tau 1985 e Marria Kacos i te Whare Wānanga o New South Wales i Ahitereiria, ā, i muri i te neke atu i te rua tekau tau o te rangahau me te whanaketanga, kei te tata te hangarau ki te pakeketanga. I Hapani, kei te tere te whanaketanga o ngā pākahiko vanadium momo-pūmau (he rerekē ki te EV) mō ngā teihana hiko whakahaere tihi me te rokiroki pūngao hau, ā, kua whakamahia, kua hokohokohia hoki ngā pūnaha rokiroki pūngao pākahiko vanadium mana-teitei.
Ko te pūngao hiko opākahiko vanadiumka rongoatia hei pūngao matū i roto i te electrolyte waikawa whanariki o ngā katote vanadium o ngā āhua valence rerekē, me tewaipēhi hikohikoKa tukuna te pēhanga ki roto i te puranga pākahiko e te papu o waho. I raro i te mahi a te mana miihini, ka huri te pēhanga waipēhi hikohiko i roto i ngā tāke rokiroki wai rerekē me te porowhita kati o te haurua pākahiko. Ka whakamahia te kiriuhi whakawhiti proton hei diaphragm o te kete pākahiko, ā, ka rere te otinga electrolyte i te taha whakarara o te mata o te electrode ka puta te tauhohenga electrochemical. Ka hurihia te pūngao matū e rongoa ana i roto i te otinga hei pūngao hiko mā te kohikohi me te kawe i te iahiko mā roto i ngā pereti electrode takirua. Mā tēnei tukanga tauhohenga whakahurihuri ka taea te utu, te tuku me te whakahou maeneene i te pākahiko vanadium. Ko te electrolyte pai he mea hanga mai i te otinga ionic V(Ⅴ) me te V(Ⅳ) , ko te electrolyte kino he mea hanga mai i te otinga ionic V(Ⅲ) me te V(Ⅱ) , te utu pākahiko, te rauemi pai mō te otinga ionic V(Ⅴ) , te otinga ionic V(Ⅱ) , te tukunga pākahiko, te electrode pai me te kino mō te otinga ionic V(Ⅳ) me te V(Ⅲ) , ko te pākahiko o roto mā te kawe H+. Kei roto i te wairewa waikawa ngā katote V(Ⅴ) me V(Ⅳ) i te āhua o te katote VO2+ me te katote VO2+, nō reira ka taea te whakaatu i ngā tauhohenga pai me ngā tauhohenga kino o ngā pākahiko vanadium penei:
Irahiko pai i te wā e utu ana: VO2++H2O→VO2++2H++e-
Irahiko kino ina utu ana: V3++ e-→V2+
Ānōte tukunga: VO2++2H++e-→VO2++H2O
Irahiko tukunga kino: V2+→V3++ e-
Ka whakamahia hei pūnaha rokiroki hiko,ngā pākahiko vanadiumkei a rātou ngā āhuatanga e whai ake nei
1, ko te mana putanga o te pākahiko e whakawhirinaki ana ki te rahi o te puranga pākahiko, ko te kaha rokiroki pūngao e whakawhirinaki ana ki te rokiroki me te kukū o te electrolyte, no reira he tino ngāwari tana hoahoa, ina tino mohio te mana putanga, ka taea te whakanui ake i te kaha rokiroki pūngao, mena ka whakanuia te rahinga o te tank rokiroki electrolyte, ka whakapai ake ranei i te kukū o te electrolyte;
2, kei roto i te wai te matū hohe o te pākahiko vanadium, kotahi anake te katote electrolytekatote vanadium, nō reira kāore he huringa āhua o ētahi atu pākahiko i te wā e utu ana, e whakawātea ana hoki, he roa te ora o te pākahiko;
3, he pai te mahi utu me te tukunga, ka taea te tukunga hohonu me te kore e kino te pākahiko;
4. He iti te tukunga-ā-roto, ina kei roto te pūnaha i te aratau kati, kāore he āhuatanga tukunga-ā-roto o te electrolyte i roto i te tāke;
5, te herekore o te tūnga o te pākahiko vanadium, ka taea e te pūnaha te mahi aunoa me te kati, kāore he parahanga, he ngawari te tiaki, he iti te utu whakahaere;
6, kāore he pahūtanga pea, he tūponotanga ahi rānei o te pūnaha pākahiko, he tino haumaru;
7, ko te nuinga o ngā wāhanga pākahiko he rauemi waro iti te utu, he kirihou hangarau, he nui ngā rauemi, he ngāwari ki te hangarua, kāore e hiahiatia he konganuku utu nui hei whakakorikori hiko;
8, he tino pai te whai hua o te pūngao, tae atu ki te 75% ~ 80%, he tino utu nui te mahi;
9. Tere tīmatanga tere, ki te kī tonu te tauhohenga i te electrolyte, ka taea te tīmata i roto i te 2 meneti, ā, ko te pana āhua utu me te tukunga e hiahia ana ki te 0.02s i te wā e mahi ana.
