The primary objective of this investigation was to determine the feasibility of using conducting, iodinated polymers as cathode materials for high energy-density, high power-density electrochemical cells with lithium as the anode. The following nitrogen-bearing, conjugated polymers were either prepared or were purchased: 2-polyvinylpyridine, cyclized polyacrylonitrile, aniline black, paracyanogen, polyquinoxaline and polybenzimidizole. Only the first three polymers exhibited high electrical conductivity when reacted with iodine.
