Asebenza kanjani amabhethri e-Redox Flow
Ukuhlukaniswa kwamandla namandla kuwumehluko oyinhloko wama-RFB, uma kuqhathaniswa namanyeamasistimu okugcina ama-electrochemical.Njengoba kuchaziwe ngenhla, amandla esistimu agcinwa kumthamo we-electrolyte, okungaba kalula nangokwezomnotho kube kububanzi bamahora angama-kilowatt kuya kumashumi ama-megawatt-amahora, kuye ngobukhulu beamathangi okugcina.Amandla esistimu anqunywa ubukhulu besitaki samaseli e-electrochemical.Inani le-electrolyte eligeleza kusitaki se-electrochemical nganoma isiphi isikhathi akuvamile ukuba libe ngaphezu kwamaphesenti ambalwa yenani eliphelele le-electrolyte ekhona (ngezilinganiselwa zamandla ezihambisana nokuphuma kwamandla alinganiselwe amahora amabili kuya kwayisishiyagalombili).Ukugeleza kungamiswa kalula ngesikhathi sephutha.Njengomphumela, ukuba sengozini kwesistimu ekukhishweni kwamandla okungalawuleki esimweni sama-RFB kukhawulelwe ukwakheka kwesistimu kumaphesenti ambalwa wengqikithi yamandla agciniwe.Lesi sici siphambene nezakhiwo ezihlanganisiwe, ezihlanganisiwe zesitoreji seseli (i-lead-acid, i-NAS, i-Li Ion), lapho amandla aphelele esistimu exhunywe ngaso sonke isikhathi futhi etholakalayo ukuze akhishwe.
Ukuhlukaniswa kwamandla namandla nakho kunikeza ukuguquguquka kwedizayini ekusetshenzisweni kwama-RFB.Amandla wamandla (usayizi wesitaki) angafanelana ngokuqondile nomthwalo ohlobene noma impahla ekhiqizayo.Amandla okugcina (usayizi wamathangi okugcina) angenziwa ngokuzimela ehambisana nesidingo sokugcina amandla sohlelo oluthile.Ngale ndlela, ama-RFB anganikeza ngokomnotho isistimu yokugcina ethuthukisiwe yohlelo ngalunye.Ngokuphambene, isilinganiso samandla kumandla sigxilile kumaseli ahlanganisiwe ngesikhathi sokuklama nokukhiqizwa kwamaseli.Umnotho wesikali ekukhiqizeni amaseli ukhawulela inani elingokoqobo lemiklamo ehlukene yamaseli etholakalayo.Ngakho-ke, izinhlelo zokusebenza zokugcina ezinamaseli ahlanganisiwe ngokuvamile zizoba namandla eqile noma amandla.
Ama-RFB angahlukaniswa abe izigaba ezimbili: 1) iqinisoamabhethri okugeleza kwe-redox, lapho zonke izinhlobo zamakhemikhali ezisebenzayo ekugcineni amandla zincibilika ngokuphelele kusixazululo ngaso sonke isikhathi;kanye 2) namabhethri okugeleza kwe-hybrid redox, lapho okungenani uhlobo lwekhemikhali olulodwa lugqitshwa njengento eqinile kumaseli e-electrochemical ngesikhathi sokushajwa.Izibonelo zama-RFB eqiniso zihlanganisaizinhlelo ze-vanadium-vanadium ne-iron-chromium.Izibonelo zama-RFB ayingxube zifaka i-zinc-bromine kanye nezinhlelo ze-zinc-chlorine.
