REDOX DEVICE OF A METAL-AIR FLOW BATTERY

A redox device of a metal-air flow battery includes a container, a rod inserted into and electrically insulated from the container, a net connected to and surrounding the rod, a power supply, and an ultrasonic module. The container, the rod, and the net are electrically conductive, respectively. The net moves away from the rod gradually in a spiral manner. The container receives an electrolyte solution containing a product originated from the metal-air flow battery. The net is immersed in the electrolyte solution. The power supply is electrically connected to the container, the rod, and the net to form an electric loop via the electrolyte solution. The power supply provides a pulse current to the electric loop to electrochemically deposit metal from the electrolyte solution on the net. The ultrasonic module provides vibrations to the container to shake off metal from the net and suspend the metal in the electrolyte solution.
