PROJECT TITLE : Ultracapacitors Using Diamond-Like Nanocomposite Films

TECHNICAL ABSTRACT (LIMIT 200 WORDS)

The use of ultracapacitor technology in energy storage devices and other cost and lifetime sensitive applications is limited by several factors such as energy density, specific power, cost (including materials and production costs) and lifetime. Current approaches and technologies do not adequately address these issues. Several of these problems can be overcome effectively by utilizing ART's novel and highly tailorable Diamond-Like Nanocomposite (DLN) thin film technology. DLN films exhibit good adhesion to a variety of substrate materials, high electrical resistivity (1014 W-cm), high dielectric breakdown (106 - 108 V/cm) and dielectric constant in the range of 3-20. DLN films offer the potential of replacing conventional polymeric dielectrics with a durable, thermally stable, hard thin film coating with high energy density, high dielectric breakdown, and reduced weight.

The workplan includes demonstration of high dielectric breakdown, high energy density of DLN capacitance structures on a variety of substrate materials, and design and fabrication of large area capacitance multilayers. The capacitance structures will be tested at ART, at State University of New York at Buffalo and United Technologies Research Center. Fundamental characterization of the diamond-like properties of the films will be performed at ART. Finally, a structure-processing-property correlation will also be attempted.

POTENTIAL COMMERCIAL APPLICATIONS
DLN based ultracapacitors for defibrillators, pulsed power units for vehicle propulsion, power stabilizers for computers, hand-held tools and navigational aids. Other applications include electrostatic chucks for semiconductor industry, pulse accelerators, lasers, memories, camcorders, backup devices on computers. Applications requiring tailored dielectric and resistivity properties such as printer/copier rollers and thin film resistive heaters.
