Njengendawo lapho kwenzeka khona ukusabela,isitaki se-vanadiumihlukaniswe nethangi lokugcina i-electrolyte, elinqoba ngokuyinhloko isimo sokuzikhipha kwamabhethri endabuko. Amandla ancike kuphela kusayizi we-stack, futhi umthamo uncike kuphela ekugcinweni nasekugxilweni kwe-electrolyte. Umklamo uguquguqukayo kakhulu; uma amandla engaguquki, ukwandisa umthamo wokugcina amandla, kuyadingeka kuphela ukwandisa umthamo wethangi lokugcina i-electrolyte noma ukwandisa umthamo noma ukugxilwa kwe-electrolyte. Yebo, ngaphandle kokushintsha usayizi we-stack; inhloso "yokushaja okusheshayo" ingafezwa ngokufaka noma ukufaka i-electrolyte esimweni sokushaja. Ingasetshenziswa ukwakha i-kilowatt-level ibe yi-100-megawatt eneriziteshi zamandla zokugcina igesi, ezinokuzivumelanisa nezimo okuqinile.
I-VRFBinenkululeko enkulu ekukhetheni indawo futhi ithatha indawo encane. Uhlelo lungavalwa ngokuphelele futhi lusetshenziswe ngaphandle kwenkungu ye-asidi kanye nokugqwala kwe-asidi. I-electrolyte ingasetshenziswa kabusha, akukho ukukhishwa kwegesi, ukulungiswa okulula kanye nezindleko zokusebenza eziphansi. Kuwubuchwepheshe bokugcina amandla aluhlaza. Ngakho-ke, ekukhiqizeni amandla avuselelekayo, amabhethri e-vanadium ayizithako ezifanele kakhulu zamabhethri e-lead-acid.
Ibhethri leVanadiumIbonisa impilo yesistimu ende. Ukusebenza kahle kwesistimu kuphezulu. Ukusebenza kahle komjikelezo wesistimu yebhethri ye-vanadium kungafinyelela ku-65-80%. Isekela ukushaja nokukhipha njalo. Amabhethri e-Vanadium asekela ukushaja nokukhipha njalo kwamanje okuphezulu, futhi angashajwa futhi akhishwe izikhathi ezingamakhulu ngosuku ngaphandle kokunciphisa umthamo webhethri. Isekela ukushaja ngokweqile nokukhipha ngokweqile. Uhlelo lwebhethri ye-vanadium lusekela ukushaja okujulile nokukhipha (DOD 80%) ngaphandle kokulimaza ibhethri. Isilinganiso sokushaja nokukhipha siyi-1.5:1. Uhlelo lwebhethri ye-vanadium lungafinyelela ukushaja nokukhipha okusheshayo ukuze kuhlangatshezwane nezidingo zomthwalo. Izinga eliphansi lokuzikhipha. Izinto ezisebenzayo kuma-electrolyte amahle nangalungile e-amabhethri e-vanadiumzigcinwa emathangini ahlukene. Kumodi yokuvala uhlelo, i-electrolyte ethangini ayinayo into yokuzikhipha.
Ukuqalisa kuyashesha. Ngesikhathi sokusebenza kweuhlelo lwebhethri le-vanadium, isikhathi sokushaja nokukhipha ibhethri singaphansi kwe-1 millisecond/umklamo wohlelo lwebhethri uyaguquguquka. Amandla kanye nomthamo wohlelo lwebhethri le-vanadium kungaklanywa futhi kulungiselelwe ngokuzimela ngokwezidingo zamakhasimende ukuze kufezwe ukuthuthukiswa okusheshayo. Izindleko zokulungisa eziphansi. Uhlelo lwebhethri le-vanadium lusebenza ngokuzenzakalelayo ngokuphelele, izindleko zokusebenza eziphansi, isikhathi eside sokulungisa kanye nokugcinwa okulula. Lunobungani nemvelo futhi alungcolisi. Uhlelo lwebhethri le-vanadium luvaliwe ekamelweni lokushisa futhi luhlangabezana nezidingo zokuvikela imvelo. Lungatholakala ngokuphelele ngaphandle kwezinkinga zokulahla.
