A commercially deployed 12-year-old vanadium flow battery is evaluated. Capacity and efficiency are stable since commissioning; no leakages occur. Small capacity loss is restored by rebalancing procedure of the electrolyte. Electrochemical impedance spectroscopy is applied to investigate stack degradation.
This demonstrates the advantage that the flow batteries employing vanadium chemistry have a very long cycle life. Furthermore, electrochemical impedance spectroscopy analysis was conducted on two of the battery stacks. Some degradation was observed in one of the stacks reflected by the increased charge transfer resistance.
The energy is stored in the vanadium electrolyte kept in the two separate external reservoirs. The system capacity (kWh) is determined by the volume of electrolyte in the storage tanks and the vanadium concentration in solution. During operation, electrolytes are pumped from the tanks to the cell stacks then back to the tanks.
The all-vanadium flow battery (VFB) employs V 2 + / V 3 + and V O 2 + / V O 2 + redox couples in dilute sulphuric acid for the negative and positive half-cells respectively. It was first proposed and demonstrated by Skyllas-Kazacos and co-workers from the University of New South Wales (UNSW) in the early 1980s , .
Our solar power systems and energy storage products are engineered for reliability, safety, and efficient deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
