Abstract"High energy density capacitors will serve various commercial and military applications, such as pulse power systems, pulsed lasers, high energy switches, radar modulators, and directed energy weapons. However, today¿¿s capacitors, especially high energydensity storage capacitors, are the weakest link in power electronic system reliability. For many military and industrial power electronic systems, capacitors with several orders of magnitude improvement in energy density are needed. In this Phase Iproposal, Boston Applied Technologies (BAT) proposes an innovative and low-cost technology to fabricate novel nanostructured electrolytes for high power capacitors. The innovative planar boundary nanostructured electrolyte is capable to have a permittivity10 times better than any thin film materials available to date and low dielectric loss. Both the electrolyte nanolayers and electrode layers will be deposited using the metal-organic chemical liquid deposition method developed by scientists and engineersat BAT. We anticipate achieving high performance nanostructured electrolyte capable for ultrahigh energy density capacitors with capacitance per unit area of about 100 ¿YF/cm2 and energy density of 40 J/g. Capacitors made from the proposed planar boundarynanostructured electrolyte will be at least 5 times smaller than those state-of-the-arts power capacitors with the same output energy. Success in the Phase I effort will lead to the comme
