| Research Abstract |
To achieve high-performance rechargeable batteries, we have proposed molecular cluster batteries (MCBs), in which the cathode active materials are polynuclear metal complexes (molecular clusters) such as Mn12 and polyoxometalate clusters with multi-electron redox reactions. MCBs exhibited a larger capacity and a more rapid charging than usual Li ion batteries. In-situ X-ray absorption fine structure (XAFS) analysis on MCBs revealed that super-reduction of molecular clusters caused a large capacity. We also demonstrated that nano-hybridization of molecular clusters and single walled carbon nanotubes modified the battery performance of MCBs such as high capacities and rapid charging.
