Vanadium ions in vanadyl sulfate serve as non-cross-phase redox substances, a bromine complexing agent is added into an organic solvent to be combined with bromine to generate a high-solubility hydrophobic active substance, the battery cost is reduced, the device design is simplified, the theoretical capacity of the battery is improved, and a series of battery cycle and service life problems caused by irregular growth of zinc metal are avoided.
