Performance Improvement in Redox Flow Battery With Flow-Through Channel Geometry

Redox Flow battery attracts much attention as one of the efficient rechargeable batteries because of its versatility for small and large scale energy storage. Although this battery has great potentials, further improvement on cell performance to achieve high current density is necessary for industrial implementation. In this study, we applied flow-through (interdigitated) channel geometry to a redox flow battery for enhancement of electrode utilization by advection transport. As a result, it is confirmed that the redox flow battery showed better performance by using interdigitated channels than ones with serpentine channels.
