Njengendawo apho kwenzeka khona impendulo,isitaki sevanadiumyahlulwe kwitanki yokugcina i-electrolyte, eyoyisa ngokusisiseko imeko yokuzikhupha ngokwayo kwiibhetri zemveli. Amandla axhomekeke kuphela kubukhulu be-stack, kwaye amandla axhomekeke kuphela kugcino lwe-electrolyte kunye noxinzelelo. Uyilo luguquguquka kakhulu; xa amandla engaguquki, ukwandisa amandla okugcina amandla, kuyimfuneko kuphela ukwandisa umthamo wetanki yokugcina i-electrolyte okanye ukwandisa umthamo okanye uxinzelelo lwe-electrolyte. Ewe, ngaphandle kokutshintsha ubungakanani be-stack; injongo "yokutshaja kwangoko" inokufezekiswa ngokutshintsha okanye ukongeza i-electrolyte kwimeko yokutshaja. Ingasetyenziselwa ukwakha i-kilowatt-level ukuya kwi-100-megawatt enerizitishi zamandla zokugcina umbane, ezinokuguquguquka okuqinileyo.
I-VRFBinomlinganiselo omkhulu wokukhululeka ekukhetheni indawo kwaye ithatha umhlaba omncinci. Inkqubo ingavalwa ngokupheleleyo kwaye isebenze ngaphandle kwe-acid inkungu kunye nokugqwala kwe-asidi. I-electrolyte inokusetyenziswa kwakhona, akukho kukhutshwa kwegesi, ukulungiswa okulula kunye neendleko zokusebenza eziphantsi. Yiteknoloji yokugcina amandla aluhlaza. Ke ngoko, ukuvelisa amandla ahlaziyekayo, iibhetri zevanadium ziindawo ezifanelekileyo zokutshintsha iibhetri ze-lead-acid.
Ibhetri yeVanadiumIbonisa ubomi benkqubo obude. Ukusebenza kakuhle kwenkqubo kuphezulu. Ukusebenza kakuhle komjikelo wenkqubo yebhetri yevanadium kunokufikelela kwi-65-80%. Ixhasa ukutshaja nokukhupha rhoqo. Iibhetri zeVanadium zixhasa ukutshaja nokukhupha rhoqo, kwaye zinokutshaja nokukhupha amaxesha amaninzi ngemini ngaphandle kokunciphisa amandla ebhetri. Ixhasa ukutshaja nokukhupha ngaphezulu. Inkqubo yebhetri yevanadium ixhasa ukutshaja nokukhupha okunzulu (DOD 80%) ngaphandle kokonakalisa ibhetri. Umlinganiselo wokutshaja nokukhupha yi-1.5:1. Inkqubo yebhetri yevanadium inokufezekisa ukutshaja nokukhupha ngokukhawuleza ukuhlangabezana neemfuno zomthwalo. Izinga eliphantsi lokuzikhupha. Izinto ezisebenzayo kwi-electrolytes ezilungileyo nezingalunganga zeiibhetri zevanadiumzigcinwa kwiitanki ezahlukeneyo. Kwimo yokuvala inkqubo, i-electrolyte ekwitanki ayinanto yokuzikhupha ngokwayo.
Ukuqalisa kuyakhawuleza. Ngexesha lokusebenza kweinkqubo yebhetri yevanadium, ixesha lokutshaja nokukhupha ibhetri lingaphantsi kwe-1 millisecond/uyilo lwenkqubo yebhetri luyaguquguquka. Amandla kunye nomthamo wenkqubo yebhetri yevanadium unokuyilwa kwaye ulungiselelwe ngokuzimeleyo ngokweemfuno zabathengi ukuze kufezekiswe uphuculo olukhawulezileyo. Iindleko zokulungisa eziphantsi. Inkqubo yebhetri yevanadium ifezekisa ukusebenza ngokuzenzekelayo ngokupheleleyo, iindleko zokusebenza eziphantsi, ixesha elide lokulungisa kunye nokugcinwa okulula. Inobuhlobo nokusingqongileyo kwaye ayinangcoliseko. Inkqubo yebhetri yevanadium ivaliwe kubushushu begumbi kwaye ihlangabezana neemfuno zokhuseleko lokusingqongileyo. Ingabuyiselwa ngokupheleleyo ngaphandle kweengxaki zokulahla.
