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 کاملGraphite oxide - based graphene materials as positive electrodes in vanadium redox flow batteries
Two graphene materials, TRGO-1 and TRGO-2, prepared by the thermal exfoliation/reduction at 1000oC of two graphite oxides with different characteristics, are investigated as positive electrodes in a Vanadium Redox Flow Battery (VRFB). A detailed study of their electrochemical response towards the [VO2]/[VO] redox system is carried out through cyclic voltammetry, electrochemical impedance spectr...
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...
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 کاملDesign and development of unit cell and system for vanadium redox flow batteries (V-RFB)
Vanadium redox flow battery (V-RFB) has been attracted by many researches; some are under field testing and demonstration stage, but information on construction, experimental characterization, electrolyte preparation, overall systems under study, etc. are still limited. This paper focus on the technical issues faced and the lessons learnt during the development of unit cell and system for V-RFB...
