Therefore, engraving flow patterns on electrodes for the flow-through structure is another potential strategy for scaled-up battery design. In summary, the serpentine and interdigitated flow fields are still the most popular patterns for RFBs.
Geometric parameters of flow fields play a crucial role in deciding the battery performance by directly influencing the mass transport process and flow resistance. It is worth noting that adjusting the parameters usually affects the electrochemical performance and hydraulic performance inversely.
Results show that shortening the supply path and enhancing the supply rate by utilizing flow channel structures within the unit area are key factors determining the uniform distribution of active materials
