Nonlinear Dielectric Materials and Processing for High-Energy-Density Capacitors

TRS Technologies, Inc. proposes to develop high energy density capacitors with stable dielectric properties for utilization in pulse power systems. The proposed ceramic capacitor will combine the best features of high energy density, low dielectric loss and high reliability. The capacitors developed on this program will have an energy density>4J/cc, low power dissipation (tanf<0.005), and high operation voltage. Nonlinear antiferroelectric material with high energy density will be fabricated into multilayer capacitor with fine grained and defect free microstructure to have high breakdown strength, high energy density and high reliability through fine ceramic processing with nanopowder. BENEFIT: The proposed program will enable development of multilayer capacitors with high energy density and high application voltage for pulse power application. Successful development and commercialization of these capacitors will enable development of compact, light weighted pulsed power supplies for wide range of applications including military directed energy systems based on aircraft, ships, and ground vehicles.
