High Energy Density Nanocomposite Based on Tailored Surface Chemistry

High energy density capacitors are required for practical implementation of GW-class pulse power loads. In response to this need, TPL has established unique dielectric and capacitor capabilities. Revolutionary materials, designs and manufacturing process have been developed for power sources that have potential for an order of magnitude reduction in mass and volume relative to current commercially available systems. The technology is based on novel nanocomposite formulations that can be reliably formed into capacitors of complex shape and efficiently scaled for system integration. At present, TPL’s nanocomposite capacitors are capable of delivering the necessary sub-microsecond power with an energy density greater than any established technology. The proposed development will focus on advancing this technology by investigating nanopowder surface chemistries for increased composite voltage stress capability and energy density. Doping processes developed by TPL for ceramic capacitors will be applied to modifying titanate nanopowders to achieve tailored vacancy structures and charge transfer behavior. Experimental data will be acquired on capacitors and reconciled against theoretical, atomic-scale modeling at University of Connecticut. It is the overall program objective to establish a predictive model for charge behavior at particle-polymer interfaces and define an approach to delivering capacitors that meet Air Force requirements. BENEFIT: Successful completion of the proposed program will benefit development in several defense related power conditioning, control electronics and directed energy systems. High energy electrical storage systems with reduced size and weight are required for applications including: high energy laser, high power microwave, electric armor, electric guns, electric launch, particle accelerators and ballistic missile applications.
