✦ Synopsis

Octamethylcyclotetrasiloxane

was polymerized by RF-plasma polymerization to provide a host polymer film which was hybridized with poly-(propylene oxide) and lithium perchlorate. Rechargeable, all-solid-state lithium batteries were fabricated using a thin film of TiS, (10 -15 pm) prepared by chemical vapor deposition (CVD) as a cathode active material, and an ultra-thin film of solid polymer electrolyte (2 -3 pm) as an electrolyte. The batteries were examined in respect of their charge/discharge properties at room temperature at current densities of 8 -40 PA cme2. The first discharge and charge reached the 90% level.
