Increase in energy storage of capacitors enables reduction in size of the capacitor banks. The key to reducing the size of these systems is to develop capacitors with much higher energy density (5-10 J/cc) than polymer film capacitors based on biaxially oriented polypropylene (BOPP, 1 - 2 J/cc) and ceramic capacitors based on BaTiO3 (0.1 J/cc). Current metal oxide or electrolytic capacitors produced by anodization of the metal (eg Ta) using liquid electrolytes or low conductivity electrodes such as MnO2 are limited in their operation above 10 kHz making them unsuitable for advanced high frequency (>100 kHz up to 100 MHz) pulse discharge applications. In this Phase I, TRS proposes to develop high energy density, pulse discharge capacitors (> 10J/cc) using amorphous metal (Ta, Zr, Nb) oxide thin films on metallized flexible polymer substrates (such as mylar and kapton). Benefits: The primary application for this technology is energy storage capacitors for pulse-discharge systems and DC bus capacitors for power electronic modules such as DC-AC converters and AC inverters. Much of the pulsed power market is for emerging military systems such as electromagnetic and directed energy weapons, electromagnetic armor, and electromagnetic aircraft launchers. The major thrust for this market is high-energy systems for combat vehicles such as tanks, aircraft, and ships. Other commercial applications include external and implanted defibrillators, lighting, and industrial power supplies, and power conditioning devices. Return
