Super-capacitors possess the attribute of having large specific capacitance, combined with large power densities. These attributes make small super-capacitors ideal charge storage devices for distributed and embedded applications such as those for coupling or powering small robotic systems, distributed sensors / actuators and bio-medical devices. The designed self-packaged device was done using DuPont 951-Y4 LTCC and compatible conducting pastes.The type of super-capacitor implemented is an EDL device, with Ag paste electrical terminals, carbide derived carbon electrodes materials and (EMI-BTI) as the electrolyte.Different super-capacitors, spanning in dimensions from 1 cm2 to 9 cm2 active electrode geometrical area were designed. Polycrystalline carbon was used as the sacrificial phase to preserve internal volume during firing, and the two electrodes were fired separately and joined after assembly using epoxy.The capacitors were characterized for its capacity, electrode charge storage efficiency power and energy density using conventional cyclic voltammetry, and impedance measurements.
