ABSTRACT:
Novel cathode materials for use in electrochemical cells are disclosed. The cathode materials consist essentially of a conductive solution comprised of iodine dissolved in a mixture of two organic pyridine-based constituents, both of which function as donors to form complexes with iodine. Preferably, the cathode materials further include, in addition to the dissolved iodine, an iodine solid phase suspended therein. Large amounts of the iodine solid phase, relative to the dissolved iodine, may be used.
