✦ Synopsis

Several conductive polymers (polyacetylene, polypyrrole, polythiophene, polyiminodibenxyl, polycarbaxole, polyfuran, polyphenothiaxine) have been synthesized by a chemical polymerization method and examin ed for their suitabiity as positive electrode material for lithium secondary batteries. A test cell, using polypyrrole as a positive electrode, showed good charge/discharge characteristics. Oxidixing agents for the synthesis of polypyrrole have been investigated for further improvement, and polypyrrole prepared by a new method of synthesis using a Cu(BF,),/nitrile system exhibited excellent performance.
