Ibhetri yeVanadium Redox Flow, igama elipheleleyo leVanadium REDOX flow battery (VRB), luhlobo lwebhetri yeREDOX apho izinto ezisebenzayo zijikeleza kwimeko yolwelo. Iibhetri ze-iron-chromium REDOX bezikho ukusukela ngeminyaka yoo-1960, kodwa iibhetri zevanadium REDOX zacetywa ngo-1985 nguMarria Kacos kwiYunivesithi yaseNew South Wales eOstreliya, kwaye emva kweminyaka engaphezu kwamashumi amabini yophando nophuhliso, le teknoloji isondele ekuvuthweni. EJapan, iibhetri zevanadium zohlobo olusisigxina (ngokuchaseneyo ne-EV) zezikhululo zamandla ezilawula incopho kunye nokugcinwa kwamandla omoya ziphuhliswa ngokukhawuleza, kwaye iinkqubo zokugcina amandla ebhetri yevanadium enamandla aphezulu ziye zasetyenziswa kwaye zathengiswa.
Amandla ombaneibhetri yevanadiumigcinwa njengamandla eekhemikhali kwi-sulfuric acid electrolyte yee-ion zevanadium zeemeko ezahlukeneyo ze-valence, kwayei-hydraulic ye-electrolyticUxinzelelo lufakwa kwinqwaba yebhetri ngepompo yangaphandle. Phantsi kwesenzo samandla oomatshini, uxinzelelo lwe-hydraulic lwe-electrolytic lujikeleza kwiitanki ezahlukeneyo zokugcina ulwelo kunye ne-loop evaliweyo yesiqingatha sebhetri. I-membrane yokutshintshana kweproton isetyenziswa njenge-diaphragm yephakheji yebhetri, kwaye isisombululo se-electrolyte sihamba ngokuhambelana nomphezulu we-electrode kwaye kwenzeka i-electrochemical reaction. Amandla eekhemikhali agcinwe kwisisombululo aguqulwa abe ngamandla ombane ngokuqokelela nokuqhuba umbane ngeepleyiti ze-electrode ezimbini. Le nkqubo yokusabela eguqukayo ivumela ibhetri yevanadium ukuba itshajwe, ikhutshwe kwaye itshajwe kakuhle. I-electrolyte echanekileyo inesisombululo se-ionic se-V(Ⅴ) kunye ne-V(Ⅳ), i-electrolyte engalunganga inesisombululo se-ionic se-V(Ⅲ) kunye ne-V(Ⅱ), ukutshajwa kwebhetri, izinto ezichanekileyo zesisombululo se-ionic se-V(Ⅴ), isisombululo se-ionic se-V(Ⅱ), ukukhutshwa kwebhetri, i-electrode engalunganga kunye ne-negative ngokulandelelana kwesisombululo se-ionic se-V(Ⅳ) kunye ne-V(Ⅲ), ibhetri yangaphakathi nge-H+ conduction. Ii-ion ze-V(Ⅴ) kunye ne-V(Ⅳ) zikhona ngohlobo lwe-ion ye-VO2+ kunye ne-ion ye-VO2+ ngokulandelelanayo kwisisombululo se-asidi, ngoko ke iimpendulo ezilungileyo nezingalunganga zeebhetri ze-vanadium zingabonakaliswa ngolu hlobo lulandelayo:
I-electrode elungileyo ngexesha lokutshaja: VO2++H2O→VO2+2H++e-
I-electrode engalunganga xa itshaja: V3++ e-→V2+
I-anode yokukhupha itshaja: VO2++2H++e-→VO2++H2O
I-electrode engalunganga yokukhupha itshaja: V2+→V3++ e-
Isetyenziswa njengenkqubo yokugcina amandla,iibhetri zevanadiumbaneempawu ezilandelayo
1, amandla okukhupha ebhetri axhomekeke kubungakanani benqwaba yebhetri, amandla okugcina amandla axhomekeke kwindawo yokugcina i-electrolyte kunye noxinzelelo, ngoko ke uyilo lwayo luguquguquka kakhulu, xa amandla okukhupha eqinisekile, ukwandisa amandla okugcina amandla, lo gama nje ukwandisa umthamo wetanki yokugcina i-electrolyte okanye ukuphucula uxinzelelo lwe-electrolyte;
2, into esebenzayo yebhetri yevanadium ikhona kulwelo, i-ion ye-electrolyte inye kuphelai-vanadium ion, ngoko ke akukho tshintsho lwesigaba kwezinye iibhetri xa zitshajwa kwaye zikhutshwa, ibhetri inobomi obude benkonzo;
3, ukutshaja, ukusebenza kakuhle kokukhupha, kungaba nokukhupha okunzulu ngaphandle kokonakalisa ibhetri;
4. Ukuzikhupha okuphantsi, xa inkqubo ikwimo evaliweyo, i-electrolyte ekwitanki ayinanto yokuzikhupha ngokwayo;
5, inkululeko yendawo yebhetri yevanadium, inkqubo inokuba ngokuzenzekelayo ngokupheleleyo ukusebenza ivaliwe, akukho ungcoliseko, ulondolozo olulula, iindleko zokusebenza eziphantsi;
6, inkqubo yebhetri ayinayo ingozi yokuqhuma okanye yomlilo, ikhuselekile kakhulu;
7, iindawo zebhetri ikakhulu zizinto zekhabhoni ezingabizi kakhulu, iiplastiki zobunjineli, imithombo yezinto eziphathekayo ityebile, kulula ukuzisebenzisa kwakhona, azidingi zisinyithi ezixabisekileyo njenge-electrode catalyst;
8, ukusebenza kakuhle kwamandla aphezulu, ukuya kuthi ga kwi-75% ~ 80%, ukusebenza ngexabiso eliphezulu kakhulu;
9. Isantya sokuqalisa esikhawulezayo, ukuba i-reactor igcwele i-electrolyte, ingaqaliswa kwimizuzu emi-2, kwaye iswitshi yokutshaja nokukhupha i-state ifuna kuphela imizuzwana eyi-0.02 ngexesha lokusebenza.
