PLASMA-POLYMERIZED CARBON-DISULFIDE THIN-FILM RECHARGEABLE BATTERIES

This paper discusses the results on deposition conditions, rates of po lymerization, and properties of carbon disulfide films prepared by two techniques, viz., plasma polymerization and argon-plasma-assisted pol ymerization of carbon disulfide. A higher rate of polymerization and s ulfur content was obtained for carbon disulfide films prepared by the plasma-polymerization technique. A Li/LiClO4 propylene carbonate/PPCS cell was assembled using lithium foil, 2 M LiCO4/PC electrolyte with p olyolefin separator, and PPCS deposited on Pt foil. The electrode area was 1.3 cm(2). The cell cycled reversibly between 1 and 3 V and retai ned its capacity (5 mA h/g) well over 12 cycles.
