Redox flow cell
Image
Schematic diagram:
The redox flow cell is an accumulator and works, so to speak, with liquid electrode materials, e.g., with zinc (Zn) and bromine (Br).

Description:
The graphic shows the flow of the electrode material during discharging of the cell. Two graphite electrodes (black surfaces) collect the current. Zinc is oxidized at its electrode, while the bromine is reduced at its electrode.
During charging, voltage is applied and the two solutions are pumped past the electrodes again.
Information and ideas:
What advantages does this process have over conventional galvanic cells?
