Zinc–bromine flow batteries (ZBFBs) have advanced to the demonstration phase for projects with a 100 kW h capacity, indicating promising application prospects. One critical concern is their low-temperature operation, which affects reliability, potential applications, and. . Frigid environments notably impair the electrochemical performance of zinc–bromine flow batteries (ZBFBs) due to polybromide solidification, restricting their widespread deployment in cold regions. Here, two independently used complexing agent cations, n -propyl- (2-hydroxyethyl)-dimethylammonium. . A zinc-bromine battery is a rechargeable battery system that uses the reaction between zinc metal and bromine to produce electric current, with an electrolyte composed of an aqueous solution of zinc bromide. Zinc has long been used as the negative electrode of primary cells. However, many opportunities. .
