| Research Abstract |
Poly-nuclear metal complexes, molecular clusters, are promising as next-generation electron storage materials since they exhibit more than ten electrons redox. In this work, we developed nanohybrid materials between one of molecular clusters, polyoxometalate (POM), and nanocarbons such as graphene and mesoporous carbon, and then their battery performances were investigated in details. As a result, extremely large capacities were obtained due to a combination of a super-reduction of POM and electrical double layer capacitances of nanocarbons which are enhanced by nanohybridization. Additionally, we also developed an in situ electrochemistry-magnetic measurement system and applied it to magnetic clusters. Then, we succeeded in changing magnetic properties such as transition temperatures and coercivities continuously, which opens an avenue to electrochemical magnets.
