Uburyo bateri za Redox Flow zikora

Gutandukanya ingufu n'ingufu ni itandukaniro rikomeye hagati ya RFBs, ugereranije n'izindisisitemu zo kubika amashanyaraziNkuko byasobanuwe haruguru, ingufu z'urusobe rw'amashanyarazi zibikwa mu rugero rwa electrolyte, zishobora kuba mu masaha ya kilowati kugeza kuri megawati icumi, bitewe n'ingano yaibigega byo kubikamo ibintu. Ubushobozi bw'ingufu za sisitemu bugenwa n'ingano y'urutonde rw'uturemangingo tw'amashanyarazi. Ingano ya electrolyte itembera mu rutonde rw'amashanyarazi igihe icyo ari cyo cyose ntabwo iruta igice cy'ijana cy'ingano yose ya electrolyte ihari (ku bipimo by'ingufu bihwanye n'isohoka ku ngufu zigenwe mu masaha abiri kugeza ku munani). Urujya n'uruza rw'amazi rushobora guhagarikwa byoroshye mu gihe cy'ikosa. Kubera iyo mpamvu, ingaruka za sisitemu ku kurekurwa kw'ingufu zidagenzurwa mu gihe cya RFBs zigarukira ku gipimo cy'ingufu zose zibitswe. Iki kintu gitandukanye n'imiterere y'uturemangingo ipakiye, ihujwe (aside lead, NAS, Li Ion), aho ingufu zose za sisitemu zihuzwa igihe cyose kandi ziboneka kugira ngo zisohoke.

Gutandukanya ingufu n'ingufu bitanga kandi uburyo bworoshye bwo gushushanya mu ikoreshwa rya RFB. Ubushobozi bw'ingufu (ingano y'ingufu) bushobora guhindurwa hakurikijwe umutwaro cyangwa igikoresho gifitanye isano. Ubushobozi bwo kubika (ingano y'ibigega byo kubika) bushobora guhindurwa ku buryo bwihariye hakurikijwe ibyifuzo by'ububiko bw'ingufu by'ikoreshwa ryihariye. Muri ubu buryo, RFB zishobora gutanga uburyo bwo kubika neza kuri buri porogaramu. Mu buryo bunyuranye, igipimo cy'ingufu ku ngufu gishyirwaho ku turemangingo twinjijwe mu gihe cyo gushushanya no gukora utwo turemangingo. Ubukungu bw'ingano mu ikorwa ry'uturemangingo bugabanya umubare w'imiterere itandukanye y'uturemangingo ihari. Bityo, uburyo bwo kubika hamwe n'uturemangingo twinjijwe mu turemangingo akenshi bugira imbaraga nyinshi cyangwa ubushobozi bw'ingufu.

RFB zishobora kugabanywamo ibyiciro bibiri: 1) ukuribateri zikoreshwa mu gutunganya redox, aho ubwoko bwose bw'ibinyabutabire bukora mu kubika ingufu bushonga neza mu buryo buhoraho; na 2) bateri za redox zivanze, aho nibura ubwoko bumwe bw'ibinyabutabire bushyirwa nk'ikintu gikomeye mu tunyabutabire twa electrochemical mu gihe cyo gushyushya. Ingero za RFB nyazo zirimosisitemu ya vanadium-vanadium na icyuma-chromiumIngero za RFB zivanze zirimo zinc-bromine na zinc-chlorine.
