Ibhetri yeVanadium Redox Flow (VFBs)zibuchwephesha obuvelayo bokugcina amandla obunamandla abalulekileyo, ngakumbi kwizinga elikhulu, izicelo zokugcina ixesha elide. Ngokungafaniyo nesiqhelougcino lwebhetri olugcwalisekayo, Ii-VFB zisebenzisa isisombululo se-vanadium electrolyte kuzo zombini i-electrode efanelekileyo kunye ne-negative, ezenza zibe zizodwa kuyilo kunye nokusebenza.
Yintoni ibhetri yeVanadium Redox Flow?
Iibhetri ye-vanadium redox (VRB), eyaziwa ngokuba yi-vanadium flow battery (VFB) okanye i-vanadium redox flow battery (VRFB), luhlobo lwebhetri ehlaziywayo.
Isebenzisa i-vanadium ion kwiindawo ezahlukeneyo ze-oxidation ukugcina kunye nokukhulula amandla ombane. Ngokungafaniyo neebhetri eziqhelekileyo, ii-VRFBs zigcina amandla kwii-electrolytes ezingamanzi ezijikeleza kwisistim kune-electrode eqinileyo. Olu luyilo luvumela ukuhla kunye nokuguquguqukaizisombululo zokugcina amandla.
Amacandelo angundoqo weBanadium Redox Flow ibhetri
| iCandelo eliPhambili | Inkcazo |
| Electrolytes | - I-VRFB isebenzisa i-electrolyte engamanzi amabini, ehlala iqulethe i-vanadium kwiindawo ezahlukeneyo ze-oxidation (V²⁺, V³⁺, V⁴⁺, kunye ne-V⁵⁺). |
| Ii-electrodes | - Ii-electrode ezimbini (ngokuqhelekileyo i-carbon okanye izinto ezifanayo) ziququzelela ukuphendulwa kwe-redox (ukunciphisa kunye ne-oxidation) ukukhulula okanye ukugcina amandla. |
| Imembrane | - I-membrane ye-proton-conducting (ehlala yenziwe nge-Nafion) ihlula izisombululo ezimbini ze-electrolyte, ivumela ukuhamba kwe-ion phakathi kwamacala amabini ngexesha lomjikelo wokuhlawula / ukukhupha. |
| Iimpompo kunye neNkqubo yokuHamba | - Ezi zixhobo zijikeleza i-electrolytes nge-cell electrochemical cell, iqinisekisa ukuhamba okuqhubekayo kwe-vanadium ions kwinkqubo yokuguqula amandla. |
Isebenza njani ibhetri yeVanadium Redox Flow?
- 1. Umjikelo wokukhupha
- Ngexesha lokukhutshwa, i-vanadium ion kwizisombululo ze-electrolyte ezintle kunye ne-negative zifumana i-oxidation kunye nokunciphisa ukuphendula kwi-electrodes, ukukhulula amandla ombane.
- 2. Umjikelo wentlawulo
- Ngexesha lokutshaja, amandla agcinwa ngokubuyisela umva i-oxidation kunye nokunciphisa ukuphendula, ukuhambisa i-vanadium ion ibuyele kwiindawo zabo zokuqala ze-oxidation. Le nkqubo ibandakanya ukusebenzisa umsinga wangaphandle kwinkqubo.
- 3. Ii-Electrolyte eziqukuqelayo
- Uphawu oluphambili lweebhetri zokuhamba kukusetyenziswa kwee-electrolyte zolwelo ezimpontshwa kwinkqubo, evumela amandla ebhetri ukuba anyuswe ngokulula ngokwandisa ubungakanani beetanki zokugcina i-electrolyte.
