Description of the Related Art In recent years, due to the necessity of improving the efficiency of operation of power generation and transmission facilities and improving the global environment, a power storage technology for load leveling has been desired. Redox Flow, a type of battery
A battery has been developed and put into practical use. A redox flow battery stores electricity in a positive and negative electrode electrolyte solution (vanadium sulfuric acid aqueous solution), and when the positive and negative electrode electrolyte solution circulates inside the battery cell by a pump, the valence of vanadium ion, which is an active material, changes. As a result, charging / discharging is performed. Since the output (cell part) and the capacity (tank part) can be separated, the layout according to the installation location is possible, and long-term charging and discharging can be achieved simply by increasing the electrolytic solution capacity. It has features such as high-speed response, high output capability, easy maintenance and excellent recyclability.
