| Research Abstract |
Much attention has been attracted to development of novel cathode active materials to realize high performance rechargeable batteries. Among of various materials, disulfide compounds are promising due to their stable electrochemical redox behavior based on disulfide groups. In this work, we tried to develop a novel and convenient method to synthesize functional disulfide polymers under solvent-free conditions for the applications to cathodes. As a result, we synthesized these polymers by coupling reactions of thiosulfonic S-ester with dithiol. We fabricated Li batteries including synthesized disulfide polymers as cathode active materials. Their battery performances were better than those of the usual Li ion batteries.
