Nanostructured Electrocatalysts for All-Vanadium Redox Flow Batteries
Chemistry - an Asian Journal, 2015 AbstractVanadium redox reactions have been considered as a key factor affecting the energy efficiency of the all‐vanadium redox flow batteries (VRFBs). This redox reaction determines the reaction kinetics of whole cells. However, poor kinetic reversibility and catalytic activity towards the V2+/V3+ and VO2+/VO2+ redox couples on the commonly used ...

The Vanadium Redox Flow Battery: an Asymptotic Perspective
SIAM Journal on Applied Mathematics, 2019Summary: Asymptotic methods are used to analyze a time-dependent two-dimensional (2D) model for the operation of a vanadium redox flow battery -- an energy storage technology that has attracted much attention recently. The model takes into account mass, momentum, and charge conservation involving a total of seven ionic species in two porous electrodes ...

Electrolyte Flow in Vanadium Redox Flow Batteries
ECS Meeting Abstracts, 2019The redox reactions inside a Vanadium Redox Flow Battery (VRFB) are catalyzed by a porous carbon felt electrode, through which the vanadium containing electrolyte is pumped. Thus, a high Electrochemically Active Surface Area (ECSA), corresponding to a high saturation of the porous electrode, is beneficial to the performance.
