Uburyo Bateri ya Redox itemba ikora

Gutandukanya imbaraga ningufu ni itandukaniro ryingenzi rya RFBs, ugereranije nizindisisitemu yo kubika amashanyarazi. Nkuko byasobanuwe haruguru, ingufu za sisitemu zibikwa mubunini bwa electrolyte, ishobora byoroshye kandi mubukungu kuba murwego rwa kilowatt-amasaha kugeza kuri megawatt-icumi, bitewe nubunini bwaibigega byo kubikamo. Ubushobozi bwa sisitemu bugenwa nubunini bwa stack ya selile yamashanyarazi. Ingano ya electrolyte itemba mumashanyarazi mumwanya uwariwo wose ntikunze kuba hejuru ya bike kwijana ryumubare wuzuye wa electrolyte ihari (kubipimo byingufu zijyanye no gusohora ingufu zagenwe mumasaha abiri cyangwa umunani). Urujya n'uruza rushobora guhagarikwa byoroshye mugihe cyamakosa. Nkigisubizo, sisitemu yibasiwe ningufu zitagenzuwe mugihe cya RFBs bigarukira kububiko bwa sisitemu kugeza kuri bike kwijana ryingufu zose zabitswe. Iyi mikorere itandukanye nububiko bwapakiwe, bwubatswe bwububiko bwububiko (aside-aside, NAS, Li Ion), aho ingufu zose za sisitemu zahujwe igihe cyose kandi zikaboneka kugirango zisohoke.

Gutandukanya imbaraga nimbaraga nabyo bitanga igishushanyo mbonera mugukoresha RFBs. Ubushobozi bwimbaraga (ubunini bwa stack) burashobora guhuzwa neza nu mutwaro ujyanye cyangwa kubyara umutungo. Ubushobozi bwo kubika (ingano yububiko) burashobora kwigenga kubwububiko bukenewe bwa porogaramu yihariye. Muri ubu buryo, RFBs irashobora gutanga ubukungu muburyo bwiza bwo kubika kuri buri porogaramu. Ibinyuranye, igipimo cyingufu ningufu gishyirwaho ingirabuzimafatizo mugihe cyo gushushanya no gukora selile. Ubukungu bwikigereranyo mubikorwa byingirabuzimafatizo bugabanya umubare ufatika wibishushanyo mbonera bitandukanye birahari. Kubwibyo, kubika porogaramu hamwe na selile zisanzwe bizagira imbaraga zirenze imbaraga cyangwa imbaraga.

RFBs ishobora kugabanywamo ibyiciro bibiri: 1) ukuribateri ya redox, aho ubwoko bwimiti yose ikora mukubika ingufu zishonga burundu mugisubizo igihe cyose; na 2) bateri ya Hybrid redox itemba, aho byibuze imiti imwe yashizwemo nkikintu gikomeye mumashanyarazi mugihe cyo kwishyuza. Ingero za RFB zukuri zirimosisitemu ya vanadium-vanadium na sisitemu-ibyuma bya chromium. Ingero za Hybrid RFBs zirimo zinc-bromine na sisitemu ya zinc-chlorine.
