Abstract
Relaxor terpolymers (PVDF-TrFe-CTFE) exhibit dielectric constants > 60, 20 to 30 times the value of conventional film dielectrics such as polypropylene and polyester. As a result the new terpolymer has an energy density of over 10 J/cc at half the electric field of conventional polymer film. For the proposed effort TRS and Prof. Qiming Zhang of Penn State will fabricate wound prototype capacitors from terpolymer film and test them for energy density, equivalent series resistance, insulation resistance, and charge/discharge speed. The goal for this program will be to demonstrate a 0.1 to 1 microFarad, 5 J/cc wound capacitor with a discharge speed faster than 10 microseconds.
