The structure of the storage battery mainly comprises: a positive electrode, a negative electrode, an electrolyte solution and a separator, while the corresponding flow battery further comprises pumps for positive and negative electrodes, pipelines, storage tanks, etc. With regard to the two structures of the flow battery and the storage battery, the materials of the positive and negative electrodes are both a porous carbon felt, and the material of the separator is a polymer material, wherein for the storage battery, the electrolyte solution is stored in the porous electrode, whereas for the flow battery, the electrolyte solutions of the positive and negative electrodes flow through the positive and negative electrodes via the pumps and pipelines, and finally return to the storage tanks, thereby achieving the circulation of the electrolyte solutions in electrode chambers and the storage tanks. In addition, the electrolyte solutions of the positive and negative electrodes are neutral solutions with a specific composition of a zinc salt and a manganese salt, wherein same are not corrosive to the electrodes and current collectors. During the process of charging, MnO 2  in the positive electrode can be directly oxidized into α-MnO 2 ; and during the process of discharging, MnO 2  is dissolved into Mn 2+ . Unlike the intercalation-deintercalation mechanism of traditional zinc-manganese secondary batteries, this mode of dissolution-deposition can avoid the problem of the structure of the materials collapsing during cycle processes, and therefore, the cycle lifetime of the battery is greatly prolonged. Moreover, the reaction involves a two-electron transfer, thereby greatly increasing the energy density of the battery.
