Mabatire a Vanadium Redox Flow (VFBs)ndi njira yosungiramo mphamvu yomwe ikubwera yomwe ili ndi kuthekera kwakukulu, makamaka muzinthu zazikulu, zosungirako kwa nthawi yayitali. Mosiyana ndi ochiritsirayosungiranso batire, VFBs amagwiritsa ntchito njira ya vanadium electrolyte pa maelekitirodi abwino ndi oipa, kuwapangitsa kukhala apadera pakupanga ndi kugwira ntchito.
Kodi Vanadium Redox Flow Battery Ndi Chiyani?
Thebatri ya vanadium redox (VRB), yomwe imadziwikanso kuti vanadium flow battery (VFB) kapena vanadium redox flow battery (VRFB), ndi mtundu wa batire yothamangitsidwanso.
Imagwiritsa ntchito ma ion vanadium m'maiko osiyanasiyana oxidation kuti isunge ndikutulutsa mphamvu zamagetsi. Mosiyana ndi mabatire wamba, ma VRFB amasunga mphamvu mu ma electrolyte amadzimadzi omwe amazungulira m'dongosolo osati mu maelekitirodi olimba. Mapangidwe awa amalola kuti scalable ndi kusinthasinthanjira zosungira mphamvu.
Zigawo Zofunikira za Battery Flow ya Vanadium Redox
| Chigawo Chofunikira | Kufotokozera |
| Electrolytes | - VRFB imagwiritsa ntchito ma electrolyte awiri amadzimadzi, omwe nthawi zambiri amakhala ndi vanadium m'malo osiyanasiyana a okosijeni (V²⁺, V³⁺, V⁴⁺, ndi V⁵⁺). |
| Ma electrode | - Ma electrode awiri (kawirikawiri kaboni kapena zinthu zofananira) amathandizira machitidwe a redox (kuchepetsa ndi okosijeni) kuti amasule kapena kusunga mphamvu. |
| Chiwalo | - Proton-conducting membrane (yomwe nthawi zambiri imapangidwa ndi Nafion) imalekanitsa njira ziwiri za electrolyte, zomwe zimalola kuti ion ikuyenda pakati pa mbali ziwirizi panthawi ya malipiro / kutulutsa. |
| Mapampu ndi Flow System | - Zigawozi zimazungulira ma electrolyte kudzera mu cell electrochemical, kuonetsetsa kuti ma ion vanadium akuyenda mosalekeza pakusintha mphamvu. |
Kodi Battery Flow ya Vanadium Redox Imagwira Ntchito Motani?
- 1. Kuthamangitsidwa Kozungulira
- Pakutuluka, ma ion vanadium mu njira zabwino ndi zoipa za electrolyte amakumana ndi oxidation ndikuchepetsa zochita pa maelekitirodi, kutulutsa mphamvu zamagetsi.
- 2. Charge Cycle
- Panthawi yolipira, mphamvu imasungidwa potembenuza makutidwe ndi okosijeni ndi kuchepetsa zomwe zimachitika, ndikusuntha ma ion vanadium kubwerera kumadera awo oyambira oxidation. Njirayi imaphatikizapo kugwiritsa ntchito mphamvu yakunja ku dongosolo.
- 3. Ma Electrolytes Oyenda
- Chofunikira chachikulu cha mabatire otaya ndi kugwiritsa ntchito ma electrolyte amadzimadzi omwe amapopedwa kudzera mu dongosolo, zomwe zimapangitsa kuti mphamvu ya batire ionjezeke mosavuta ndikungokulitsa kukula kwa matanki osungira ma electrolyte.
Ubwino wa Vanadium Redox Flow Mabatire
- √ Scalability
Ma VRFB amatha kukulitsidwa mosavuta powonjezera kukula kwa akasinja a electrolyte, kuwapangitsa kukhala abwino kwambiri pakusungirako mphamvu zazikulu monga kusanja kwa gridi ndi kusungirako mphamvu zongowonjezwdwa. - √ Moyo Wautali Wozungulira
Vanadium sanyozeka pakakwera njinga (chifukwa imagwiritsa ntchito zinthu zomwezo pama electrolyte abwino komanso oyipa), zomwe zimapangitsa VRFB kukhala ndi moyo wautali wogwira ntchito poyerekeza ndi ma chemistries ena a batri.
Naturgy adatumiza batire iyi ya vanadium ku Zamora, Spain.
- √Chitetezo
Ma VRFB ndi otetezeka chifukwa ma electrolyte sangayaka komanso alibe poizoni. Mawonekedwe amadzimadzi amachepetsanso chiwopsezo cha kuthawa kwamafuta, chomwe chingakhale chodetsa nkhawa mumitundu ina ya mabatire. - √ Kuchita bwino
Ma VRFB amatha kukhala ndi maulendo obwereza (chiperesenti cha mphamvu zomwe zabwezedwa panthawi yotulutsidwa) kuyambira 65% mpaka 85%, kutengera kapangidwe kake ndi magwiridwe antchito. -
√ Kuchepetsa Mphamvu ndi Mphamvu
Ma VRFB amatha kudziyimira pawokha mphamvu (kukula kwa akasinja a electrolyte) ndi mphamvu (kukula kwa magawo a electrochemical cell), zomwe zimawapatsa kusinthasintha kwa ntchito zosiyanasiyana.
