| Outline of Final Research Achievements |
Sustainable development for low-carbon society needs electrochemical energy storage devices capable of efficient electricity supply. In this project, we studied charge storage in confined nanospace for the development of high energy density electrochemical supercapacitors. Combined assessment of experiments and computations found that ions and solvent molecules confined in nanospace possess anomalous dielectric response to the external electric field, which enables dense charge storage. Using this anomalous behavior, we successfully demonstrated high energy density charge storage in confined nanospace between transition-metal carbide nanosheets MXenes, which provides technological foundations to achieve electrochemical supercapacitors with higher energy density.
