Plasma-Polymerized Carbon Disulfide Thin-Film Rechargeable Batteries

This paper discusses the results on deposition conditions, rates of polymerization, and properties of carbon disulfide films prepared by two techniques, viz., plasma polymerization and argon-plasma-assisted polymerization of carbon disulfide. A higher rate of polymerization and sulfur content was obtained for carbon disulfide films prepared by the plasma-polymerization technique. A Li/LiClO 4 propylene carbonate/PPCS cell was assembled using lithium foil, 2 M LiClO 4 /PC electrolyte with polyolefin 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 retained its capacity (5 mA h/g) well over 12 cycles.
