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 کاملNovel catalytic effects of Mn3O4 for all vanadium redox flow batteries.
A new approach for enhancing the electrochemical performance of carbon felt electrodes by employing non-precious metal oxides is designed. The outstanding electro-catalytic activity and mechanical stability of Mn(3)O(4) are advantageous in facilitating the redox reaction of vanadium ions, leading to efficient operation of a vanadium redox flow battery.

متن کاملV5+ degradation of sulfonated Radel membranes for vanadium redox flow batteries.
Insight into the degradation mechanisms of aromatic proton conducting membrane separators for vanadium redox flow batteries (VRFBs) is urgently needed for the development of long lifetime VRFBs. Other than in-cell observations of performance degradation, there is little fundamental evidence on the specific degradation pathways of aromatic ion exchange membranes for VRFBs. Herein we investigated...
