6 FAQs about Flow battery stack design

What are the practical aspects of flow batteries?

Recent contributions on flow batteries have addressed various aspects, including electrolyte, electrode, membrane, cell design, etc. In this review, we focus on the less-discussed practical aspects of devices, such as flow fields, stack and design considerations for developing high performance large-scale flow batteries.

Can a flow cell be scaled to a stack-scale battery?

More significantly, there exist many issues when scaling up the flow cell toward the stack-scale batteries. In engineering applications, the stack consists of several flow cells that have enlarged active areas, as shown in Fig. 1 d.

How do design principles apply to stack-scale batteries?

The design principles also apply to stack-scale batteries. With an enlarged active area, there will be more patterns in the flow field library, which increases the cost of dataset construction and neural network training.

Can redox flow batteries be used in large-scale energy storage applications?

Finally, we provide suggestions for further studies on developing advanced flow batteries and large-scale flow battery stacks. Rechargeable redox flow batteries are being developed for medium and large-scale stationary energy storage applications.

How to model a flow battery?

It is worth noting that the channel depth and electrode thickness are taken into account to calculate the velocity magnitude and maintain the mass conservation at the boundary of two regions . Another modeling strategy for flow batteries is to simulate the segmented channels/electrodes with connected flow resistances.

How can numerical modeling help a battery stack?

In the future, numerical modeling is expected to assist flow pattern optimization and provide scale-up pathways for practical applications. In addition, the scaling of flow-field-structured configuration on a graphite plate would highly increase the capital cost of a battery stack.
