Redox Flow Battery Ua Haujlwm li cas

Kev sib cais ntawm lub zog thiab lub zog yog qhov sib txawv tseem ceeb ntawm RFBs, piv rau lwm yamelectrochemical cia systems. Raws li tau piav qhia saum toj no, lub zog hluav taws xob yog khaws cia hauv qhov ntim ntawm electrolyte, uas tuaj yeem yooj yim thiab kev lag luam nyob rau hauv thaj tsam ntawm kilowatt-teev mus rau kaum ntawm megawatt-teev, nyob ntawm qhov loj ntawmcov tank cia. Lub zog muaj peev xwm ntawm qhov system yog txiav txim siab los ntawm qhov loj ntawm pawg ntawm cov kab hluav taws xob electrochemical. Tus nqi ntawm cov electrolyte ntws hauv cov khoom siv hluav taws xob hauv ib lub sijhawm twg yog qhov tsis tshua muaj ntau tshaj li ob peb feem pua ​​​​ntawm tag nrho cov nyiaj electrolyte tam sim no (rau cov kev ntsuas hluav taws xob sib thooj rau kev tso tawm ntawm lub zog ntsuas rau ob mus rau yim teev). Flow tuaj yeem nres tau yooj yim thaum muaj teeb meem txhaum cai. Raws li qhov tshwm sim, qhov tsis muaj zog rau lub zog tsis muaj peev xwm tso tawm nyob rau hauv rooj plaub ntawm RFBs raug txwv los ntawm qhov system architecture rau ob peb feem pua ​​​​ntawm tag nrho lub zog khaws cia. Cov yam ntxwv no yog qhov sib piv nrog cov ntim khoom, kev sib koom ua ke ntawm cov khoom siv ntawm tes (lead-acid, NAS, Li Ion), qhov twg tag nrho lub zog ntawm lub cev txuas nrog txhua lub sijhawm thiab muaj rau kev tso tawm.

Kev sib cais ntawm lub zog thiab lub zog kuj muab kev tsim qauv yooj yim hauv kev siv RFBs. Lub zog muaj peev xwm (pawg loj) tuaj yeem ncaj qha mus rau qhov cuam tshuam los yog tsim cov khoom vaj khoom tsev. Lub peev xwm khaws cia (qhov loj ntawm cov tso tsheb hlau luam) tuaj yeem hloov kho ntawm nws tus kheej raws li lub zog cia xav tau ntawm daim ntawv thov tshwj xeeb. Nyob rau hauv txoj kev no, RFBs tuaj yeem tsim kev lag luam muab qhov chaw cia zoo rau txhua daim ntawv thov. Hauv qhov sib piv, qhov piv ntawm lub zog rau lub zog yog tsau rau cov hlwb sib xyaw ua ke thaum lub sijhawm tsim thiab tsim cov hlwb. Economies ntawm scale nyob rau hauv cell ntau lawm txwv cov tswv yim tus naj npawb ntawm txawv cell designs uas muaj. Yog li ntawd, cov ntaub ntawv khaws cia nrog cov hlwb sib xyaw feem ntau yuav muaj ntau lub zog lossis lub zog muaj peev xwm.

RFBs tuaj yeem muab faib ua ob pawg: 1) muaj tseebredox flow roj teeb, qhov twg tag nrho cov tshuaj nquag ua haujlwm hauv kev khaws cia lub zog yog tag nrho yaj hauv cov tshuaj txhua lub sijhawm; thiab 2) hybrid redox flow batteries, qhov tsawg kawg yog ib qho tshuaj lom neeg yog plated raws li cov khoom hauv electrochemical hlwb thaum them nqi. Piv txwv ntawm qhov tseeb RFBs suav nrogvanadium-vanadium thiab hlau-chromium systems. Piv txwv ntawm hybrid RFBs suav nrog zinc-bromine thiab zinc-chlorine systems.
