Manufacturable High-Energy-Density Titanium Dioxide Capacitor

The increased burden and elevated performance requirements on Department of Defense (DoD) electrical systems for power conditioning and pulsed-power applications demands next-generation passive electrical components, particularly capacitors. Current capacitors operate at lower temperatures and are bulky because of their low energy density. Ceramic dielectric capacitors offer high-temperature performance; however, available methods of preparing ceramic dielectric thin films are very limited in production capacity and not suitable for large-scale production. Giner, Inc. (Giner) proposes to develop a one-step, high-efficiency process to continuously produce thin dielectric high-temperature (>160?C) capacitors for DoD?s electrical systems. This Phase I project will focus on demonstrating the fabrication process, characterizing the ultra-thin dielectric material and demonstrating scalability of the deposition-capacitor winding process. This proposed high-temperature ceramic dielectric capacitor will possess a targeted energy density of 8-10 J/cc. In Phase II, Giner will focus on scaling up the process and fabricating and delivering >1000 J prototype capacitors to DARPA for independent evaluation in collaboration with an industry partner.
