A Numerical Simulation of Vanadium Redox Flow Batteries
The recent penetration of renewable sources in the energy system caused a transformation of the needs of the distribution system and amplified the need of energy storage systems to properly balance the electricity grid. Among electrochemical energy storage devices, all vanadium flow batteries are those of the most promising technologies due to their high efficiency, long lifetime, reliability a...
متن کاملChloride supporting electrolytes for all-vanadium redox flow batteries.
This paper examines vanadium chloride solutions as electrolytes for an all-vanadium redox flow battery. The chloride solutions were capable of dissolving more than 2.3 M vanadium at varied valence states and remained stable at 0-50 °C. The improved stability appeared due to the formation of a vanadium dinuclear [V(2)O(3)·4H(2)O](4+) or a dinuclear-chloro complex [V(2)O(3)Cl·3H(2)O](3+) in the s...

متن کاملCarbon nanoporous layer for reaction location management and performance enhancement in all-vanadium redox flow batteries
In this study, the performance and reaction location in a VRFB was investigated with a carbon paper electrode that was modified to include a thin layer of multi-walled carbon nanotubes. The nanotube layer was introduced into the electrode at locations on the negative and positive electrode nearest the membrane and nearest the flow field. Results with the nanotube layer on the positive electrode...
