| Outline of Final Research Achievements |
Disulfide compounds have attracted much attention as energy storage material whereby energy exchange occurs according to a reversible bonding construction/cleavage process, accompanied with two-electrons redox reaction. This redox couple can be suitably used for the cathode of high energy density lithium secondary batteries. The theoretical capacity is larger than that of the conventional battery materials. So far, various disulfide materials have been applied to the battery, but the cycle performance is low in spite of high capacities since they show structural changes and dissolution into the electrolyte, depending on an applied potential during electrochemical reaction. To prevent the dissolution of disulfide active materials, it is important to increase the interaction with conductive carbon in the cathode. Here we report syntheses of such disulfide compounds and their battery performances as cathode active materials.
