Technical FAQs 4

How do flow batteries perform?

The performance of flow batteries is critically influenced by mass, ion, and electron transport processes and electrochemical reactions within the heterogenous porous electrodes. Understanding these processes at the pore scale is essential because it is at this level that the fundamental mechanisms governing transport and reaction dynamics occur.

Are aqueous iron-based flow batteries suitable for large-scale energy storage applications?

Thus, the cost-effective aqueous iron-based flow batteries hold the greatest potential for large-scale energy storage application.

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 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.
