Cov Roj Teeb Redox Flow Ua Haujlwm Li Cas

Kev sib cais ntawm lub zog thiab lub zog yog qhov sib txawv tseem ceeb ntawm RFBs, piv rau lwm yamcov txheej txheem khaws cia hluav taws xobRaws li tau piav qhia saum toj no, lub zog ntawm lub cev khaws cia rau hauv qhov ntim ntawm electrolyte, uas tuaj yeem yooj yim thiab kev lag luam nyob rau hauv qhov ntau ntawm kilowatt-teev mus rau kaum tawm megawatt-teev, nyob ntawm qhov loj ntawmcov tank cia khoom. Lub peev xwm ntawm lub zog ntawm lub kaw lus yog txiav txim siab los ntawm qhov loj ntawm cov pawg ntawm cov hlwb electrochemical. Tus nqi ntawm electrolyte ntws hauv cov pawg electrochemical txhua lub sijhawm tsis tshua muaj ntau dua ob peb feem pua ​​​​​​ntawm tag nrho cov electrolyte tam sim no (rau kev ntsuas zog sib raug rau kev tso tawm ntawm lub zog ntsuas rau ob mus rau yim teev). Kev ntws tuaj yeem yooj yim raug nres thaum muaj qhov xwm txheej tsis ua haujlwm. Yog li ntawd, qhov tsis muaj zog ntawm lub kaw lus rau kev tso tawm lub zog tsis tswj hwm hauv rooj plaub ntawm RFBs yog txwv los ntawm lub kaw lus architecture rau ob peb feem pua ​​​​​​ntawm tag nrho cov zog khaws cia. Qhov feature no yog qhov sib piv nrog cov pob khoom, kev sib xyaw ua ke ntawm tes cia architectures (lead-acid, NAS, Li Ion), qhov twg tag nrho lub zog ntawm lub kaw lus txuas nrog txhua lub sijhawm thiab muaj rau kev tso tawm.

Kev sib cais ntawm lub zog thiab lub zog kuj muab kev ywj pheej tsim qauv hauv kev siv RFBs. Lub peev xwm fais fab (qhov loj ntawm pawg) tuaj yeem hloov kho ncaj qha rau qhov thauj khoom lossis cov khoom tsim khoom. Lub peev xwm khaws cia (qhov loj ntawm cov thoob dej cia) tuaj yeem hloov kho ywj pheej rau qhov xav tau khaws cia lub zog ntawm daim ntawv thov tshwj xeeb. Ua li no, RFBs tuaj yeem muab lub kaw lus khaws cia zoo tshaj plaws rau txhua daim ntawv thov. Qhov sib piv ntawm lub zog rau lub zog yog kho rau cov cell sib xyaw thaum lub sijhawm tsim thiab tsim cov cell. Kev lag luam ntawm qhov ntsuas hauv kev tsim cell txwv tus lej ntawm cov qauv tsim cell sib txawv uas muaj. Yog li ntawd, cov ntawv thov khaws cia nrog cov cell sib xyaw feem ntau yuav muaj lub zog lossis lub zog ntau dhau.

RFBs muaj peev xwm muab faib ua ob pawg: 1) tseebcov roj teeb redox ntws, qhov twg tag nrho cov tshuaj lom neeg uas ua haujlwm hauv kev khaws cia lub zog tau yaj tag nrho hauv cov kua txhua lub sijhawm; thiab 2) cov roj teeb redox flow hybrid, qhov twg tsawg kawg ib hom tshuaj lom neeg tau plated ua cov khoom khov hauv cov hlwb electrochemical thaum lub sijhawm them. Piv txwv ntawm RFBs tseeb suav nrogcov kab ke vanadium-vanadium thiab hlau-chromiumPiv txwv ntawm cov RFBs sib xyaw suav nrog zinc-bromine thiab zinc-chlorine systems.
