Abstract: Redox flow batteries for energy storageRedox flow batteries (RFB's) could be used to store energy from intermittent energy generation sources such as, wind and solar energy RFB's allow for long term energy storage in various redox states of a molecule RFB's store power and energy separately, allowing power and energy to be scaled individually as needed for a given application Carrier material can be easily replaced at the end of its lifetime 8/26/2024 Features of the ideal RFBThe ideal RFB will be low in cost and high volumetric energy density E vol = nV cell FC active n = numbers of electrons transferred V cell = cell voltage F = faraday's constant C active = concentration of active species Non-aqueous redox flow batteries can take advantage of a larger solvent window (~5.5 V for MeCN) relative to water (~1.23 V) Water-in salt window is closer to 3.2 V, and 1.7 V window can be achieved if a Pt electrode is avoided, but these windows are still lower than non-aqueous solvents
