Capacitor Technology

New materials are needed to enable next-generation capacitor technologies with high energy density (>2 J/cc), high voltage breakdown (>80 kV), and high temperature stability (>160 C) while minimizing space weight and power. Dielectrics materials and capacitor manufacturing techniques are continually being developed to meet these high performance demands. Polymer dielectrics are a key technology with the potential to improve these characteristics. Polymer film capacitors already have advantages of extremely high breakdown strength, impact resistance, ease of fabrication, and compatibility with existing capacitor manufacturing infrastructure.

CRG is developing composite materials, new manufacturing techniques, and custom polymers tailored to meet temperature stability, and dielectric constant needs for capacitors. The resulting materials are beneficial for non-lethal personal protection, directed energy applications, environmental sensors, high power radio frequency, and electric propulsion.
