Yadda Redox Flow Battery Aiki

Rarraba iko da makamashi shine maɓalli na RFBs, idan aka kwatanta da sauranelectrochemical ajiya tsarin. Kamar yadda aka bayyana a sama, ana adana makamashin tsarin a cikin ƙarar electrolyte, wanda zai iya kasancewa cikin sauƙi da tattalin arziki a cikin kewayon kilowatt-hour zuwa goma na megawatt-hours, dangane da girman girman wutar lantarki.tankunan ajiya. Ƙarfin ƙarfin tsarin yana ƙaddara ta girman tari na sel electrochemical. Adadin electrolyte da ke gudana a cikin tarin electrochemical a kowane lokaci yana da wuya fiye da ƴan kashi dari na jimlar adadin electrolyte ɗin da ake ciki (don ƙimar kuzarin da ya yi daidai da fitarwa a ƙididdige ikon na sa'o'i biyu zuwa takwas). Ana iya dakatar da kwarara cikin sauƙi yayin yanayin kuskure. Sakamakon haka, rashin lafiyar tsarin zuwa sakin makamashi mara sarrafawa a cikin yanayin RFBs yana iyakance ta tsarin gine-gine zuwa ƴan kashi na jimlar makamashin da aka adana. Wannan fasalin ya bambanta da fakitin, haɗin gine-ginen ajiya na sel (lead-acid, NAS, Li Ion), inda ake haɗa cikakken ƙarfin tsarin a kowane lokaci kuma ana samun fitarwa.

Rabewar iko da makamashi kuma yana ba da sassaucin ƙira a cikin aikace-aikacen RFBs. Ƙarfin wutar lantarki (girman tari) na iya keɓanta kai tsaye zuwa abin da ke da alaƙa ko samar da kadari. Ƙarfin ajiya (girman tankunan ajiya) za a iya keɓance shi da kansa ga buƙatar ajiyar makamashi na takamaiman aikace-aikacen. Ta wannan hanyar, RFBs na iya samar da ingantaccen tsarin ajiya na kowane aikace-aikacen tattalin arziki. Sabanin haka, an daidaita rabon iko zuwa makamashi don haɗaɗɗun sel a lokacin ƙira da kera ƙwayoyin sel. Tattalin arzikin ma'auni a cikin samar da tantanin halitta yana iyakance yawan aiki na ƙirar tantanin halitta daban-daban waɗanda ke samuwa. Don haka, aikace-aikacen ajiya tare da haɗe-haɗen sel yawanci za su sami wuce gona da iri na ƙarfi ko ƙarfin kuzari.

Ana iya raba RFB zuwa kashi biyu: 1) gaskiyaredox kwarara batura, inda dukkanin nau'in sinadarai masu aiki a cikin ajiyar makamashi suna narkar da su a cikin bayani a kowane lokaci; da 2) matasan redox na batura masu gudana, inda aƙalla nau'in sinadarai guda ɗaya aka sanya a matsayin mai ƙarfi a cikin ƙwayoyin lantarki yayin caji. Misalan RFB na gaskiya sun haɗa datsarin vanadium-vanadium da iron-chromium tsarin. Misalai na matasan RFBs sun haɗa da tsarin zinc-bromine da tsarin zinc-chlorine.
