This voltage difference drives an electrical current from the positive to the ...
What is a flow battery? | Arbin Instruments
A flow battery, also known as a redox flow battery (from the words reduction and oxidation), is a liquid-based rechargeable cell. In a traditional battery, the electrolyte is the medium through which electrons can travel between the cathode and anode. In a flow battery, the anode and cathode themselves are electrolyte solutions.
