Momwe Mabatire a Redox Flow Amagwirira Ntchito

Kulekanitsa mphamvu ndi mphamvu ndi kusiyana kwakukulu kwa ma RFB, poyerekeza ndi enamakina osungira zinthu zamagetsiMonga tafotokozera pamwambapa, mphamvu ya dongosolo imasungidwa mu voliyumu ya electrolyte, yomwe ingakhale yotsika mtengo komanso yotsika mtengo pakati pa ma kilowatt-hours mpaka ma megawatt-hours makumi ambiri, kutengera kukula kwamatanki osungiramo zinthuMphamvu ya mphamvu ya dongosolo imatsimikiziridwa ndi kukula kwa mulu wa maselo amagetsi. Kuchuluka kwa electrolyte komwe kumatuluka mu mulu wamagetsi nthawi iliyonse sikumakhala kocheperako kuposa peresenti yochepa ya kuchuluka kwa electrolyte yonse yomwe ilipo (pa ziwerengero za mphamvu zomwe zimagwirizana ndi kutulutsa mphamvu kwa maola awiri mpaka asanu ndi atatu). Kuyenda kumatha kuyimitsidwa mosavuta panthawi ya vuto. Zotsatira zake, kufooka kwa dongosolo ku kutulutsidwa kwa mphamvu kosalamulirika pankhani ya ma RFB kumachepetsedwa ndi kapangidwe ka dongosolo kufika peresenti yochepa ya mphamvu yonse yosungidwa. Mbali iyi ikusiyana ndi mapangidwe osungidwa a maselo ophatikizidwa (lead-acid, NAS, Li Ion), komwe mphamvu yonse ya dongosolo imalumikizidwa nthawi zonse ndipo imapezeka kuti itulutsidwe.

Kulekanitsa mphamvu ndi mphamvu kumaperekanso kusinthasintha kwa kapangidwe kake pakugwiritsa ntchito ma RFB. Mphamvu yamagetsi (kukula kwa stack) ikhoza kusinthidwa mwachindunji kuti igwirizane ndi katundu wogwirizana kapena chinthu chopangira. Mphamvu yosungira (kukula kwa matanki osungira) ikhoza kusinthidwa padera kuti igwirizane ndi zosowa zosungira mphamvu za ntchito inayake. Mwanjira imeneyi, ma RFB amatha kupereka njira yosungira yabwino kwambiri pa ntchito iliyonse. Mosiyana ndi zimenezi, chiŵerengero cha mphamvu ndi mphamvu chimakhala chokhazikika pa maselo ophatikizidwa panthawi yopanga ndi kupanga maselo. Chuma cha kukula kwa kupanga maselo chimachepetsa kuchuluka kwa mapangidwe osiyanasiyana a maselo omwe alipo. Chifukwa chake, mapulogalamu osungira omwe ali ndi maselo ophatikizidwa nthawi zambiri amakhala ndi mphamvu yochulukirapo kapena mphamvu.

Ma RFB akhoza kugawidwa m'magulu awiri: 1) zoonamabatire oyenda a redox, komwe mitundu yonse ya mankhwala yomwe imagwira ntchito posungira mphamvu imasungunuka kwathunthu mu yankho nthawi zonse; ndi 2) mabatire oyenda a redox osakanizidwa, komwe mtundu umodzi wa mankhwala umakutidwa ngati cholimba m'maselo amagetsi panthawi ya mphamvu. Zitsanzo za ma RFB enieni ndi awa:machitidwe a vanadium-vanadium ndi iron-chromiumZitsanzo za ma RFB osakanizidwa ndi monga zinc-bromine ndi zinc-chlorine systems.
