Solid State Galvanic Supercapacitor for Pulse/Sustained Power
Agency / Branch:
DOD / MDA
High energy density supercapacitors may excel in providing pulsed and sustained space power. To develop a solid state galvanic supercapacitor, ElectroChem will prepare very high surface area electrode materials and a fluoropolymer membrance modified for high lithium ion conductivity. Cells will be assembled with particular attention to extension of the ionic/electronic interface for maximum power, and will be tested for charge/discharge properties as a function of temperature, to determine the most promising cell design. The extremely high pseudocapacitance coupled with the high cell voltage will offer a theoretical capacitance three times higher than that of aqueous double-layer devices, while reversible electrode reactions, the absence of metallic lithium, and intrinsically conductive solid polymer electrolytes contribute to safety and high reliability over many cycles.
