Countering Degradation of Carbon Felt Electrodes in All-Vanadium Redox Flow Batteries (VRFB)
ECS Meeting Abstracts, 2016Carbon felt electrodes are used as electrode material in VRFB. The main reasons to use carbon felt electrodes are their corrosion resistance in acidic electrolyte, high overpotential towards hydrogen evolution reaction and low material costs. Different origins of degradation can be related to dynamic cycling conditions or to possible ...

Abstract In this study, we demonstrate a new class of poly(terphenylene) based anion exchange membranes (AEMs) with improved chemical stability and anion conductivity in vanadium redox flow batteries (VRFBs). A series of terphenyl- and biphenyl-based polymers with pendant quaternary ammonium alkyl groups were synthesized and characterized for VRFB ...

In this study, various commercialized ion conductive membrane were analyzed by chemico-physical degradation. Chemico-physical degradation of Dupont’s Nafion 212 as a reference material, and F. Co. Ltd.’s cation exchange membrane F-1, anion exchange membrane F-2, and F-3 was analyzed to confirm the characteristics suitable for VRFB’s operation.

Abstract To improve the performance of the vanadium redox flow battery (VRFB), energy losses such as pumping and ohmic losses must be reduced. Such losses occur most at the carbon felt electrode because the highly viscous electrolyte cannot circulate easily through it, and the low fiber content of the carbon felt increases the electrical resistance ...

The UV-visible spectra of V III -V II electrolytes in 3 mol dm −3 H2SO4 showed a linear relationship of absorbance to mole fraction but those of V IV -V V electrolytes did not. At all wavelengths, V IV -V V mixtures showed excess absorbance over that expected for a linear combination of the components.

Abstract The vanadium redox flow battery (VRFB) is a promising energy storage system (ESS) which can decrease the risk of power outage by storing electricity energy at non-peak time, and using at peak time. Among various ESSs, the VRFB is one of the safest and most flexible systems due to its unlimited capacity, non-explosiveness, and infinite ...
