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, 2019
Summary: 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 ...

Economics of vanadium redox flow battery membranes

Journal of Power Sources, 2015
Abstract The membrane is a key component of the vanadium redox flow battery (VRFB) in terms of electrochemical performance as well as costs. The standard material Nafion ® is cost intensive and therefore several alternative materials are in the focus of research.

Vanadium redox reactions and carbon electrodes for vanadium redox flow battery

Electrochimica Acta, 1991
The redox reactions of vanadium ions in sulfuric ,acid, which are used for anolyte and catholyte in a redox flow battery, have been investigated on a GRC (graphite reinforcement carbon) electrode. Two types of carbon fiber electrodes (GF-20 and BW-309) have been evaluated for the battery electrode.

Novel vanadium chloride/polyhalide redox flow battery

Journal of Power Sources, 2003
Abstract This paper describes a novel redox flow cell which employs a polyhalide solution in the positive half-cell electrolyte and a vanadium(II)/vanadium(III) chloride redox couple as the negative half-cell electrolyte. During charging, the bromide ions in the positive half-cell are considered to undergo oxidation to the polyhalide ion Br 2 Cl ...
