A full river battery, also known as a flow battery, is a type of electrochemical energy storage device that utilizes the flow of electrolytes between two tanks to generate electricity. Unlike conventional batteries with fixed electrodes, a flow battery separates the electrolyte storage from the electrochemical reaction zone. This allows for independent scaling of power and energy capacity.
Here's a breakdown of the process:
Electrolyte Storage: Two tanks store different electrolyte solutions. One tank holds the positively charged electrolyte (the anolyte), and the other holds the negatively charged electrolyte (the catholyte). These electrolytes contain redox-active species capable of undergoing oxidation (loss of electrons) and reduction (gain of electrons).
Electrochemical Cell: The electrolytes are pumped from their respective tanks to an electrochemical cell containing two electrodes (anode and cathode) and a membrane separating the electrolytes. The membrane prevents mixing but allows ions to pass through, completing the electrical circuit.
Energy Generation: When the electrolytes are in the cell, the redox-active species undergo electrochemical reactions. At the anode, the anolyte undergoes oxidation, releasing electrons. These electrons flow through an external circuit, providing power to a load (e.g., a home, grid). Simultaneously, at the cathode, the catholyte undergoes reduction, accepting the electrons.
Energy Storage: As the reaction proceeds, the electrolytes in the tanks change their chemical state, reflecting the stored energy. When energy is needed, the process is reversed. This reversible nature allows for deep cycling without degradation as seen in conventional batteries.
Scaling: The power output of a flow battery is determined by the size of the electrochemical cell, while the energy capacity is determined by the volume of the electrolyte tanks. This independent scaling makes them ideal for large-scale energy storage applications.
