Redox-targeted catalysis for vanadium redox-flow batteries
Nano Energy, 2018Abstract Vanadium redox-flow battery (VRB) as a promising electrochemical power source for large-scale energy storage, suffers from various polarization losses despite that it has been extensively studied in the past decades. Among these losses, the sluggish interfacial charge transfer of the vanadium species on the respective electrode renders large

Optimization of the operating point of a vanadium redox flow battery
2009 IEEE Energy Conversion Congress and Exposition, 2009Modeling a vanadium redox flow battery (VRB) is intrinsically a multiphysics task based on electrochemistry and fluid mechanics. The electrochemical model predicts the stack voltage and determines the internal losses and the vanadium concentrations within the battery whereas the mechanical model determines the power required to flow the electrolyte ...

Degradation of Carbon Electrodes in the All‐Vanadium Redox Flow Battery
ChemSusChem, 2020AbstractThe charge−discharge operation of the vanadium redox flow battery degrades the electrodes over time and results in a performance and efficiency decay. The impact of extended charge−discharge cycling operation on carbon electrodes is investigated using carbon paper as a model electrode. Electrode degradation along with 70 % degradation of charge−

In-Situ Measurement of Vanadium Crossover for the Vanadium Redox Flow Battery
Journal of The Electrochemical Society, 2019A simple in-situ method for the quantification of the crossover in redox flow batteries, adapted from an electrochemical method currently used for quantifying the hydrogen crossover in fuel cells, is proposed and used for characterizing a vanadium redox flow battery. A linear sweep voltammetry (LSV) scan is performed with the pertinent redox species in
