Indlela iibhetri zeRedox Flow ezisebenza ngayo
Ukwahlulwa kwamandla namandla yeyona nto iphambili kwiiRFB, xa kuthelekiswa nezinyeiinkqubo zokugcina iikhemikhali zombaneNjengoko kuchaziwe apha ngasentla, amandla enkqubo agcinwa kumthamo we-electrolyte, enokuba phakathi kwee-kilowatt-hours ukuya kumashumi ee-megawatt-hours, kuxhomekeke kubukhulu beiitanki zokugcinaAmandla enkqubo amiselwa bubungakanani benqwaba yeeseli ze-electrochemical. Ubungakanani be-electrolyte egeleza kwi-electrochemical stack nangaliphi na ixesha abufane bube ngaphezu kwepesenti ezimbalwa zenani lilonke le-electrolyte ekhoyo (kwiireyithingi zamandla ezihambelana nokukhutshwa kwamandla alinganisiweyo iiyure ezimbini ukuya kwezisibhozo). Ukuhamba kunokuyekiswa ngokulula ngexesha lemeko yempazamo. Ngenxa yoko, ubuthathaka benkqubo ekukhutshweni kwamandla angalawulekiyo kwimeko yee-RFB bunqunyelwe yi-system architecture ukuya kwipesenti ezimbalwa zamandla apheleleyo agciniweyo. Olu phawu luchasene ne-packed, i-integrated storage architectures (lead-acid, NAS, Li Ion), apho amandla apheleleyo enkqubo aqhagamshelwe ngamaxesha onke kwaye afumaneka ukuze akhutshwe.
Ukwahlulwa kwamandla kunye namandla kukwabonelela ngokuguquguquka koyilo ekusetyenzisweni kwee-RFB. Amandla ombane (ubukhulu be-stack) anokulungiswa ngokuthe ngqo kumthwalo okanye kwi-asethi ehambelanayo. Amandla okugcina (ubukhulu beetanki zokugcina) anokulungiswa ngokuzimeleyo ngokwemfuno yokugcina amandla yesicelo esithile. Ngale ndlela, ii-RFB zinokubonelela ngenkqubo yokugcina elungiselelweyo ngokwezoqoqosho kwisicelo ngasinye. Ngokwahlukileyo koko, umlinganiselo wamandla kumandla umiselwe kwiiseli ezidibeneyo ngexesha loyilo kunye nokuveliswa kweeseli. Uqoqosho lobungakanani kwimveliso yeeseli luthintela inani elisebenzayo leedizayini ezahlukeneyo zeeseli ezikhoyo. Ke ngoko, izicelo zokugcina ezineeseli ezidibeneyo zihlala zinamandla angaphezulu okanye amandla angaphezulu.
IiRFB zinokwahlulwahlulwa zibe ziindidi ezimbini: 1) yinyaniiibhetri zokuhamba kwe-redox, apho zonke iintlobo zeekhemikhali ezisebenzayo ekugcineni amandla zinyibilika ngokupheleleyo kwisisombululo ngamaxesha onke; kunye 2) iibhetri ze-hybrid redox flow, apho ubuncinane uhlobo olunye lweekhemikhali lufakwe njenge-solid kwiiseli ze-electrochemical ngexesha lokutshaja. Imizekelo yee-RFB zokwenyani ibandakanyaiinkqubo zevanadium-vanadium kunye ne-iron-chromiumImizekelo yee-RFB ezixutyiweyo ibandakanya iinkqubo ze-zinc-bromine kunye ne-zinc-chlorine.
