| Outline of Final Research Achievements |
Objective of this study is to develop electrochemical functional materials with assembled structures of redox-active molecules with effective ion diffusion pathways. In this study, electrochemical functional materials composed of layered inorganic compounds with an intercalated redox-active organic molecule are successfully developed. Obtained materials show reversible redox reactions in Li-ion electrolytes. The results suggste Li-ions can be electrochemically interlacated into the layered inorganic compounds with a redox-active molecule.
