Why do flow batteries use vanadium chemistry?
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.
What can improve battery lifetime in vanadium redox flow batteries?
To increase battery lifetime, room for improvement is sought in two areas: exposure of the polymeric membrane to the highly oxidative and acidic environment of the vanadium electrolyte, and poor membrane selectivity towards vanadium permeability.
