Abstract: This report is a reprint from the Proceedings of the 2006 Army Science Conference at Orlando, FL on 27  30 November 2006. We are developing structural polymeric composites with battery functionality. These devices both carry structural loads and store electrochemical energy. If designed with sufficient structural and energy efficiency, these materials could enable significant system-level weight reductions by replacing inert structural components while providing supplementary power for light load applications. To enable this concept, we have designed load-bearing properties directly into the battery electrodes and electrolyte such that each component is itself multifunctional. Carbon fiber fabric anodes, cathode-coated metal meshes, and solvent-free structural polymer electrolytes are each being developed to exhibit a desirable combination of mechanical strength and electrochemical performance. These components are being integrated using moldable, scalable, cost-effective composite processing techniques.
