Amabatiri ya Vanadium Redox Flow (VFBs)ni ikoranabuhanga rigezweho ryo kubika ingufu rifite ubushobozi bugaragara, cyane cyane mu bubiko bunini kandi bumara igihe kirekire. Bitandukanye n'ibisanzweububiko bwa bateri bushobora kongera gukoreshwa, VFBs zikoresha umuti wa vanadium electrode kuri electrode nziza na mbi, bigatuma ziba umwihariko mu miterere no mu mikorere.
Bateri ya Vanadium Redox Flow ni iki?
Itsindabateri ya vanadium redox (VRB), izwi kandi nka bateri ya vanadium flow (VFB) cyangwa bateri ya vanadium redox flow (VRFB), ni ubwoko bwa bateri ikoreshwa mu ikoranabuhanga rishobora kongera gukoreshwa.
Ikoresha ioni za vanadium mu buryo butandukanye bwo kubika no kurekura ingufu z'amashanyarazi. Bitandukanye na bateri zisanzwe, VRFBs zibika ingufu mu electrolyte z'amazi zizenguruka muri sisitemu aho kuzibika muri electrode zikomeye. Iyi miterere yemerera kwaguka no koroha.ibisubizo byo kubika ingufu.
Ibice by'ingenzi bya bateri ya Vanadium Redox Flow
| Igice cy'ingenzi | Ibisobanuro |
| Electrolyte | - VRFB ikoresha electrolyte ebyiri z'amazi, ubusanzwe zirimo vanadium mu mimerere itandukanye ya oxidation (V²⁺, V³⁺, V⁴⁺, na V⁵⁺). |
| Electrode | - Electrode ebyiri (ubusanzwe karuboni cyangwa ibikoresho bisa) zoroshya ibikorwa bya redox (kugabanya no oxidation) kugira ngo zirekure cyangwa zibike ingufu. |
| Umubiri | - Ururenda rukora porotoni (akenshi rukozwe muri Nafion) rutandukanya electrolyte ebyiri, rutuma iyoni itembera hagati y’impande zombi mu gihe cyo gusohora/gutanga umuriro. |
| Pompe na Sisitemu yo Gutemba | - Ibi bice bizenguruka electrolyte mu ngirabuzimafatizo za electrochemical, bigatuma ions za vanadium zikomeza gutembera mu buryo bwo guhindura ingufu. |
Bateri ya Vanadium Redox Flow ikora ite?
- 1. Inzira yo gusezererwa
- Mu gihe cyo gusohora, ioni za vanadium mu bisubizo bya electrolyte nziza na mbi zinyura mu buryo bwa oxidation no kugabanya ingaruka kuri electrodes, zigasohora ingufu z'amashanyarazi.
- 2. Inzira yo Gutanga Inkunga
- Mu gihe cyo gushyushya, ingufu zibikwa binyuze mu gusubiza inyuma ogisijeni no kugabanya ibikorwa, bigasubiza ioni za vanadium mu miterere yazo ya ogisijeni. Iyi nzira ikubiyemo gushyira umuriro wo hanze kuri sisitemu.
- 3. Electrolyte zitemba
- Ikintu cy'ingenzi kiranga bateri zikoresha amazi ni ugukoresha electrolyte z'amazi zinyuzwa muri sisitemu, ibyo bigatuma ubushobozi bwa bateri bwongerwa byoroshye binyuze mu kongera ingano y'ibigega byo kubikamo electrolyte.
Ibyiza bya bateri za Vanadium Redox Flow
- √ Gushobora kwaguka
VRFB zishobora kongerwa byoroshye binyuze mu kongera ingano y'ibigega bya electrolyte, bigatuma biba byiza mu kubika ingufu nyinshi nko kuringaniza imiyoboro y'amashanyarazi no kubika ingufu zishobora kuvugururwa. - √ Ubuzima bw'uruziga rurerure
Vanadium ntabwo yangirika mu gihe cyo gusiganwa ku magare (kuko ikoresha ibikoresho bimwe kuri electrolytes nziza na mbi), ibyo bigatuma VRFBs ikora igihe kirekire ugereranije n'izindi bateri.
Naturgy yashyize iyi bateri ya vanadium flow muri Zamora, muri Esipanye.
