| Outline of Final Research Achievements |
The development of the nanoporous carbon electrode with wide electrochemical window is vey significant for improving the energy-density and durability against high-voltage charge of electrochemical capacitors.
This research project focuses on a new activated-carbon electrode with particle-boundary free structure (seamless activated-carbon). The micropore-blockage and increase in internal resistance of the electrode when applying high voltage to the EDLC were investigated to clarify the capacitance-decline mechanism and to optimize the micropore structure, crystallinity, surface functionalities, and 3D structure of the electrode. As a result, it has been revealed that nitrogen doping or metal-oxide coating as surface modification is promising. Therefore, it can be said that basic knowledge to develop " super-dimensional carbon electrode" for the EDLC available to high voltage operation was acquired in this project.
