A redox flow battery (1) is mainly provided with: a charge/discharge cell (2); a positive electrode electrolyte solution tank (3); and a negative electrode electrolyte solution tank (4). The inside of the charge/discharge cell (2) is divided into a positive electrode side cell (2a) and a negative electrode side cell (2b) by a diaphragm (11). A collector plate (12) and a positive electrode (13) are contained in the positive electrode side cell (2a). An aqueous solution containing a manganese polyethyleneimine complex is supplied from the positive electrode electrolyte solution tank (3) to the positive electrode (13) through a supply pipe (3a). Consequently an energy storage battery that has durability sufficient for practical applications in a wide range of fields can be provided. |
