Vanadium redox flow batteries (VRFBs) have emerged as a leading solution, distinguished by their use of redox reactions involving vanadium ions in electrolytes stored separately and circulated through a cell stack during operation. This design decouples power and energy, allowing flexible scalability for various applications.
Various definitions for the State of Charge (SoC) in vanadium redox flow batteries (VRFB) exist, but in order not to ignore either chemical reacting system state in either the negative or positive half-cells, it is best to define State of Charge for the negative half-cell SoCNE or SoC− separately from that of the positive half-cell SoCPE or SoC +.
A vanadium/air redox flow battery (VARFB) was designed utilizing vanadium and air as the redox pairs to enhance weight-specific power output. Operating at 80 °C, the VARFB achieved both high voltage and energy efficiencies.
These performance measures include State of Charge (SoC), various efficiencies, and energy density. Efficiencies covered herein were Coulomb, energy and voltage efficiencies. Energy density of the redox flow battery is examined in substantial detail to let the reader understand some of the intricacies of evaluating this important measure.
