Disulfide, which is a sub-group of organosulfides, has been studied as a promising cathode active material. Herein, to improve battery performance, we inserted disulfide into Cu-based metal organic framework (MOF) as a ligand. As a result, the disulfide inserted MOF exhibited a high capacity based on dual redox reactions of Cu ions and disulfide ligands, and a stable cycle performance. The S K-edge X-ray absorption fine structure analyses revealed a reversible cleavage and formation of S-S bond in the MOF during discharge and charge process.
