Abstract:
Theoretical specific energy and power densities for thin film Li/LE or SPE/CP cell systems were calculated by modeling a bipolar-design polymer cathode rechargeable cell with hardware where LE, SPE and CP represent the liquid electrolyte (2M LiClO4(PC)), solid polymer electrolyte (PEO(8)LiX) and the conductive polymer(polypyrrole). The cell performance is obtained for a cation-intercalating PPy-PVS composite film which is composed of polypyrrole(PPy) into which has been incorporated the polymer anion, polyvinylsolfonate(PVS) during deposition. The energy and power densities are estimated as a function of cathode thickness (1 to 100,000 micron), active cell area (1 to 10,000 sq cm) and the number of bipolar units(1 to 100). Compared to the anion-consuming polymer cathode system, significant enhancement of specific energy was achieved. The theoretical specific energy amounts to ca. 290 Wh/kg (bare cell) and ca. 209 Wh/kg for a bipolar Li/LE or SPE/PPy-PVS cell system (with hardware). (RH)
