We design a flow field for flow-through type aqueous organic redox flow batteries (AORFBs) by placing multistep distributive flow channels at the inlet and point-contact blocks at the outlet, to achieve a uniform and adequate electrolyte supply at the electrode.
Two different configurations have been studied for these flow batteries. The first example is a photochemical cell and a RFB that are physically connected by an external electrolyte circuit 21, 22. In this case, the photocharged redox-active materials are moved into the RFB for electrochemical discharge.
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.

Besides, flow field structure also has a great influence in pressure drop of the battery. Better flow field not only can improve the mass transport in electrode but also is able to decrease the pressure drop of 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.
