I-Vanadium Redox Flow Battery (VFBs)ziwubuchwepheshe obusafufusa bokugcina amandla obunamandla amakhulu, ikakhulukazi ezinhlelweni ezinkulu, zokulondoloza isikhathi eside. Ngokungafani nezivamileisitoreji sebhethri esitshajekayo, ama-VFB asebenzisa isixazululo se-vanadium electrolyte kukho kokubili ama-electrode amahle nangalungile, okuwenza ahluke ekuklanyweni nasekusebenzeni.
Iyini i-Vanadium Redox Flow Battery?
Iibhethri ye-vanadium redox (VRB), eyaziwa nangokuthi i-vanadium flow battery (VFB) noma i-vanadium redox flow battery (VRFB), iwuhlobo lwebhethri eligelezayo elishajwayo.
Isebenzisa ama-vanadium ion ezifundazweni ezahlukahlukene ze-oxidation ukugcina nokukhulula amandla kagesi. Ngokungafani namabhethri avamile, ama-VRFB agcina amandla kuma-electrolyte awuketshezi azungeza ohlelweni kunakuma-electrode aqinile. Lo mklamo uvumela ukukala nokuguquguqukaizixazululo zokugcina amandla.
Izingxenye Ezibalulekile Zebhethri Le-Vanadium Redox Flow
| Isakhi Esibalulekile | Incazelo |
| Ama-Electrolyte | - I-VRFB isebenzisa uketshezi lwama-electrolyte amabili, ngokuvamile aqukethe i-vanadium ezimeni ezihlukene ze-oxidation (V²⁺, V³⁺, V⁴⁺, ne-V⁵⁺). |
| Ama-Electrodes | - Ama-electrode amabili (imvamisa ikhabhoni noma izinto ezifanayo) asiza ukusabela kwe-redox (ukunciphisa kanye ne-oxidation) ukukhulula noma ukugcina amandla. |
| I-membrane | - I-membrane eqhuba i-proton (evame ukwenziwa nge-Nafion) ihlukanisa izixazululo ezimbili ze-electrolyte, okuvumela ukugeleza kwe-ion phakathi kwezinhlangothi ezimbili phakathi nomjikelezo wokushaja/wokukhipha. |
| Amaphampu kanye nohlelo lokugeleza | - Lezi zingxenye zijikeleza ama-electrolyte ngengqamuzana ye-electrochemical, iqinisekisa ukugeleza okuqhubekayo kwe-vanadium ion yenqubo yokuguqula amandla. |
Isebenza Kanjani Ibhethri Le-Vanadium Redox Flow?
- 1. Umjikelezo Wokukhipha
- Ngesikhathi sokukhishwa, ama-ion e-vanadium ezixazululweni ze-electrolyte ezinhle nezingezinhle athola ukusabela kwe-oxidation nokunciphisa kuma-electrode, akhiphe amandla kagesi.
- 2. Umjikelezo Wokushaja
- Ngesikhathi sokushaja, amandla agcinwa ngokuhlehlisa ukusabela kwe-oxidation nokunciphisa, ukuhambisa ama-vanadium ion abuyele ezifundeni zawo zokuqala ze-oxidation. Le nqubo ihlanganisa ukusebenzisa i-current yangaphandle ohlelweni.
- 3. Ama-Electrolyte Agelezayo
- Isici esibalulekile samabhethri okugeleza ukusetshenziswa kwama-electrolyte awuketshezi ampontshwa ngohlelo, okuvumela amandla ebhethri ukuthi akhule kalula ngokumane kunwetshwe usayizi wamathangi okugcina i-electrolyte.
Izinzuzo Zebhethri Le-Vanadium Redox Flow
- √ I-Scalability
Ama-VRFB angakhuliswa kalula ngokukhuphula usayizi wamathangi e-electrolyte, awenze alungele izinhlelo zokusebenza ezinkulu zokugcina amandla njengokulinganisa igridi kanye nokugcinwa kwamandla avuselelekayo. - √ Ukuphila Komjikelezo Omude
