Target field of flow battery

How does flow field geometry affect redox flow batteries?

Author to whom correspondence should be addressed. In vanadium redox flow batteries, the flow field geometry plays a dramatic role on the distribution of the electrolyte and its design results from the trade-off between high battery performance and low pressure drops.

What is flow field design for redox flow battery (RFB)?

Prospects of flow field design for RFB have been exhibited. Flow field is an important component for redox flow battery (RFB), which plays a great role in electrolyte flow and species distribution in porous electrode to enhance the mass transport. Besides, flow field structure also has a great influence in pressure drop of the battery.

Which flow field is used to improve battery performance?

Except for the optimization of flow field configurations, conventional flow fields are also applied to non-rectangular active area for improving the battery performance. For example, the trapezoid flow field shows great superiority in enhancing mass transport and improving the VE compared to the conventional rectangular flow field .

Which flow cell design is best for a stack-scale battery?

Serpentine and interdigitated flow fields are the most frequently studied and compared designs. It is found that the overall battery performance heavily depends on the balance between the electrochemical polarizations and pumping work . More significantly, there exist many issues when scaling up the flow cell toward the stack-scale batteries.
