A zinc/bromine flow battery comprises an electrolyte. The electrolyte comprises an active substance, a supporting electrolyte, and an additive. The additive is selected from at least one of 1-ethyl-3-methylimidazolium bromide, 1-ethyl-3-methylimidazolium chloride, 1-carboxymethyl-3-methylimidazolium bromide, and 1-carboxymethyl-3-methylimidazolium chloride. The use of the additive can regulate the deposition morphology of zinc and suppress zinc dendrites, and can also inhibit the diffusion of bromine on the positive electrode side, thereby improving the coulombic efficiency of the battery. Moreover, the complex product formed by the additive complexed with bromine does not produce solids during long-term cycling, whereas the complex product of conventional MEP in the later stage of battery cycling forms solids which are unevenly distributed on the electrode surface, reducing the voltage efficiency of the battery and shortening the service life of the battery.
