Water crossover phenomena in all-vanadium redox flow batteries

Electrochimica Acta, 2019
Abstract Water crossover through the membrane of a vanadium redox flow battery system is not desirable because it floods one half-cell, diluting the vanadium solution on one side and consequently increasing the concentration of vanadium in the other half-cell.

Electrocatalytic Coating Electrodes in the All-Vanadium Redox Flow Battery

ECS Meeting Abstracts, 2018
Redox flow batteries (RFB) are used to reversibly transform electrical energy into chemical energy that can be stored for long periods. They are adaptable and are used for a wide range of storage capacities depending on the electrode areas and the amount of electrolyte used.

Polarization curve analysis of all-vanadium redox flow batteries

Journal of Applied Electrochemistry, 2011
We outline the analysis of performance of redox flow batteries (RFBs) using polarization curves. This method allows the researcher immediate access to sources of performance losses in flow batteries operating at steady state. We provide guidance on ‘best practices’ for use of this tool, illustrated using examples from single cells operating as vanadium

Commercializing the Chloride-Containing All Vanadium Redox Flow Battery

ECS Meeting Abstracts, 2014
In 2010, a new vanadium redox flow battery chemistry using chloride-containing supporting electrolytes was invented at Pacific Northwest National Laboratory.1,2 By adding a certain amount of chloride anions into the vanadium ions supporting solutions, stable V-Cl complexes form. This new chemistry substantially improves the electrolyte

Nanorod Niobium Oxide as Powerful Catalysts for an All Vanadium Redox Flow Battery

Nano Letters, 2013
A powerful low-cost electrocatalyst, nanorod Nb2O5, is synthesized using the hydrothermal method with monoclinic phases and simultaneously deposited on the surface of a graphite felt (GF) electrode in an all vanadium flow battery (VRB). Cyclic voltammetry (CV) study confirmed that Nb2O5 has catalytic effects toward redox couples of V(II)/V(III) at the ...

Capacity Decay and Remediation of Nafion‐based All‐Vanadium Redox Flow Batteries

ChemSusChem, 2012
AbstractThe relationship between electrochemical performance of vanadium redox flow batteries (VRBs) and electrolyte composition is investigated, and the reasons for capacity decay over charge–discharge cycling are analyzed and discussed herein. The results show that the reasons for capacity fading over real charge–discharge cycling include not only ...
