Optimizing Engineered Flow-Through Electrodes for Energy Applications

Marcus Worsley | 16-ERD-051

Executive Summary

We are exploring the use of novel additive manufacturing capabilities to fabricate prototype electrodes with controlled pore sizes and geometries in concert with computer modeling to optimize flow-through electrode designs. Understanding the significance of pore size and orientation for flow batteries can potentially allow these batteries to achieve much higher energy and power densities, with applications in water purification, catalysis, and energy storage.
