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

ABSTRACT: TRS Technologies, Inc. proposes to develop nonlinear dielectric ceramic capacitors for discharge pulse power application and reduce the production cost of cofired multilayer capacitors. In the phase I program TRS developed a new antiferroelectric composition showing energy density>4J/cc at a field as low as 200kV/cm and demonstrated that high breakdown strength can be achieved from antiferroelectric and paraelectric ceramic test capacitors. Paraelectric capacitor with a small electrode area resulted in energy density ~22J/cc indicating high energy density possibly achieved when processing conditions are optimized. In this Phase II program we propose to reduce the production cost of multilayer ceramic capacitors and to modify the process to find the optimum properties for pulse power application and research on scale up of the process for larger size and high volume prototype multilayer production. BENEFIT: The proposed program will enable development of cost efficient high energy density multilayer capacitors with high application voltage and high energy density for use in pulse power application. Successful development and commercialization of these capacitors will, in turn, enable development of compact, light weight pulsed power supplies for a wide range of applications including military directed energy systems based on aircraft, ships, and ground vehicles.
