Maitiro eRedox Flow Mabhatiri Anoshanda
Kupatsanurwa kwesimba uye simba ndiwo musiyano wakakosha weRFBs, zvichienzaniswa nedzimweelectrochemical storage systems. Sezvatsanangurwa pamusoro apa, simba rehurongwa rinochengetwa muhuwandu hwe electrolyte, iyo inogona nyore uye nehupfumi kuva muhuwandu hwe kilowatt-maawa kusvika kumakumi emaawa megawatt-maawa, zvichienderana nehukuru hwe.matangi ekuchengetera. Kugona kwesimba kweiyo system kunotarirwa nehukuru hwemurwi wemagetsi emagetsi masero. Huwandu hwe electrolyte iri kuyerera mumurwi we electrochemical chero nguva hahuna kudarika zvishoma kubva muzana zvehuwandu hwese hwe electrolyte iripo (pamwero wesimba rinoenderana nekubuda pamagetsi akayerwa kwemaawa maviri kusvika masere). Kuyerera kunogona kumiswa nyore nyore panguva yekukanganisa mamiriro. Nekuda kweizvozvo, kusadzivirirwa kwesimba kusingadzoreki kuburitswa kwesimba mune yeRFBs kunoganhurwa nehurongwa hwekuvaka kune mashoma muzana esimba rose rakachengetwa. Iyi ficha inopesana neyakaputirwa, yakasanganiswa sero yekuchengetedza zvivakwa (lead-acid, NAS, Li Ion), uko simba rakazara rehurongwa rakabatana nguva dzese uye rinowanikwa pakuburitswa.
Kupatsanurwa kwesimba uye simba kunopawo dhizaini inoshanduka mukushandiswa kweRFBs. Iko kugona kwesimba (stack saizi) inogona kurongeka zvakananga kune inosanganiswa mutoro kana kugadzira asset. Iko kugona kwekuchengetedza (saizi yematangi ekuchengetedza) inogona kuve yakazvimiririra kune iyo simba rekuchengetedza simba reiyo chaiyo application. Nenzira iyi, maRFB anogona kupa mune zvehupfumi optimized kuchengetedza sisitimu yekushandisa yega yega. Kusiyana neizvi, chiyero chesimba kune simba chakagadzirirwa masero akabatanidzwa panguva yekugadzira nekugadzirwa kwemasero. Hupfumi hwehuyero mukugadzirwa kwemasero hunodzikamisa nhamba inoshanda yemagadzirirwo akasiyana siyana anowanikwa. Nekudaro, zvikumbiro zvekuchengetera zvine maseru akasanganiswa zvinowanzova neakawandisa simba kana simba rekugona.
MaRFB anogona kukamurwa kuita mapoka maviri: 1) chokwadiredox kuyerera mabhatiri, apo marudzi ose emakemikari anoshanda mukuchengetedza simba anonyungudika zvakakwana mukugadzirisa nguva dzose; uye 2) hybrid redox inoyerera mabhatiri, apo kamwechete kemikari imwe chete inoputirwa seyakasimba mumasero e electrochemical panguva yekuchaja. Mienzaniso yechokwadi RFBs inosanganisiraiyo vanadium-vanadium uye iron-chromium masisitimu. Mienzaniso yehybrid RFBs inosanganisira zinc-bromine uye zinc-chlorine masisitimu.
