8.3: Electrochemistry- Cells and Batteries
For one thing, the battery is expected to experience zero degradation over 20,000 cycles. By design, iron flow batteries circulate liquid electrolytes to charge and discharge electrons using a process called a redox reaction, which represents a gain of electrons (reduction), and a loss of electrons (oxidation).

A flow battery is a rechargeable fuel cell in which an electrolyte containing one or more dissolved electroactive elements flows through an electrochemical cell that reversibly converts chemical energy to electrical energy. Electroactive elements are "elements in solution that can take part in an electrode reaction or that can be adsorbed on the electrode." Electrolyte is stored externally, generally in tanks, and is typically pumped through the cell (or ce…

Redox-mediated flow batteries have garnered attention as a promising large-scale energy storage technology. Proof-of-concept demonstrations highlight how incorporating solid active materials into the tank can increase energy density, but extensive work is required to achieve performance metrics for commercial adoption.
The iron flow battery can store energy up to 12 hours in existing technology with prospects of stretching it to 15 hours. Li-ion batteries are limited to a maximum of 4 hours. They are not flammable, non-toxic and there is no risk of explosion compared to Li-ion batteries.
Iron-flow batteries can provide electricity for longer durations than typical lithium-ion alternatives, lasting up to 10 hours, meaning an 150 MW battery plant could power 50,000 homes overnight.
All the above-mentioned flow batteries (with exception to the soluble lead-acid flow battery which uses the planar plate electrode) utilize porous carbon materials as the electrodes. As illustrated in Fig. 3, the reactants in electrolyte are initially transported from the electrode inlet by diffusion and dispersion (macro-scale) in the bulk, and then to …
