The performance of a redox compound in flow batteries (RFB) highly depends on the electrolytic medium and operating conditions. It is exemplified this work with commercially available relatively low-cost dye 3,4-dihydroxy-9,10-anthraquinone-2-sulfonic acid (ARS), which was used as negolyte basic medium. At high pH, ARS behavior revealed interesting features for RFB applications, such low half-w...

Vanadium redox flow batteries (VRFBs) offer the capability to store large amounts of energy cheaply and efficiently, however, there is a need for fast accurate models charge–discharge curve VRFB potentially improve battery capacity performance. We develop multifidelity model predicting VRFB. In model, we use Physics-informed CoKriging (CoPhIK) machine learning method that trained on experimenta...

This study computationally investigates the hydrodynamics of different serpentine flow field designs for redox batteries, which considers Poiseuille in channel and Darcy porous substrate. Computational Fluid Dynamics (CFD) results in-house developed code based on Finite Volume Method (FVM) conventional (CSFF) agreed well with those obtained via experiment. The deviation pressure drop was less t...
