Indlela Amabhethri E-Redox Flow Asebenza Ngayo

Ukuhlukaniswa kwamandla namandla kuwumehluko obalulekile wama-RFB, uma kuqhathaniswa namanye ama-RFBizinhlelo zokugcina izinto nge-electrochemicalNjengoba kuchaziwe ngenhla, amandla esistimu agcinwa kumthamo we-electrolyte, ongaba phakathi kwama-kilowatt-hours kuya kuma-megawatt-hours angamashumi kalula nangokwezomnotho, kuye ngobukhulu bawo.amathangi okugcina izintoAmandla kagesi esistimu anqunywa ngobukhulu benqwaba yamaseli e-electrochemical. Inani le-electrolyte eligeleza esitokisini se-electrochemical nganoma yisiphi isikhathi alivamile ukuba ngaphezu kwamaphesenti ambalwa enani eliphelele le-electrolyte elikhona (ngezilinganiso zamandla ezihambisana nokukhishwa kwamandla alinganisiwe amahora amabili kuya kwayisishiyagalombili). Ukugeleza kungamiswa kalula ngesikhathi sesimo sephutha. Ngenxa yalokho, ubuthakathaka besistimu ekukhishweni kwamandla okungalawulwa esimweni sama-RFB bunqunyelwe ukwakheka kwesistimu kumaphesenti ambalwa amandla aphelele agciniwe. Lesi sici sihlukile kuzakhiwo zokugcina amaseli ezihlanganisiwe, ezihlanganisiwe (i-lead-acid, i-NAS, i-Li Ion), lapho amandla aphelele esistimu exhunywe ngaso sonke isikhathi futhi atholakala ukuze akhishwe.

Ukuhlukaniswa kwamandla namandla nakho kunikeza ukuguquguquka komklamo ekusetshenzisweni kwama-RFB. Amandla kagesi (usayizi we-stack) angalungiswa ngqo kumthwalo ohambisanayo noma impahla ekhiqizayo. Amandla okugcina (usayizi wamatangi okugcina) angalungiswa ngokuzimela ngokwesidingo sokugcina amandla sohlelo oluthile. Ngale ndlela, ama-RFB angahlinzeka ngohlelo lokugcina olulungiselelwe ngokwezomnotho lwesicelo ngasinye. Ngokuphambene nalokho, isilinganiso samandla namandla sinqunyelwe kumaseli ahlanganisiwe ngesikhathi sokuklama nokukhiqizwa kwamaseli. Umnotho wesilinganiso ekukhiqizweni kwamaseli ukhawulela inani elisebenzayo lemiklamo yamaseli ehlukene atholakalayo. Ngakho-ke, izinhlelo zokusebenza zokugcina ezinamaseli ahlanganisiwe ngokuvamile zizoba namandla angaphezu kwamandla noma amandla.

Ama-RFB angahlukaniswa ngezigaba ezimbili: 1) iqinisoamabhethri okugeleza kwe-redox, lapho zonke izinhlobo zamakhemikhali ezisebenzayo ekugcineni amandla zincibilika ngokuphelele esixazululweni ngaso sonke isikhathi; kanye no-2) amabhethri okugeleza kwe-redox e-hybrid, lapho okungenani uhlobo olulodwa lwamakhemikhali lufakwa khona njengesiqinile kumaseli e-electrochemical ngesikhathi sokushaja. Izibonelo zama-RFB angempela zifaka phakathiizinhlelo ze-vanadium-vanadium kanye ne-iron-chromiumIzibonelo zama-RFB ahlanganisiwe zifaka phakathi izinhlelo ze-zinc-bromine kanye ne-zinc-chlorine.
