| Outline of Final Research Achievements |
Metal organic frameworks (MOFs) have attracted much attention due to their application to energy storage. So far we have suggested a facile synthetic strategy to incorporate the redox active sites on both metal and ligand. In this work, we synthesized a novel MOF (Mn-MOF) consisting of Mn ions and AQDC ligands, and examined its battery performance. The Mn-MOF battery exhibited a gravimetric capacity of 200 mAh/g, which agreed well with the theoretical value of 190 mAh/g, assuming two electrons were accepted per anthraquinone and one electron for each manganese cation, and exhibited an excellent cyclability in the cycle performance test. Operando Mn K-edge XANES analysis on the Mn-MOF battery demonstrated that the electrochemical process of Mn-MOF was explained by both redox reactions of Mn ions and anthraquinone.
We also studied the battery performance of POMOF, which is composed of MOF and polyoxometalate (POM), and the preparation of carbon materials by using MOFs as a template.
