8.Summary of Research Results

Following results has been obtained by the present project.
1) Carbon based anode materials for lithium ion battery have been developed from view point of NanoCarbons in which the structure is controlled in the range of nanometer scale to fit the applications, and present concept has been contributed to basic science as well as practical application of energy devices such as LIB and capacitors.
2) Especially the B-doping is established and contributed to commercial cell for the 3rd generation cell-phones technology. N doping is also shown as interesting specie of dopant for nanocarbons.
3) The concept of nanocarbon has been developed by initiation of the present project, and the relationships between the performances and structure controlled carbon are established by termination of the dangling bonds of carbon hexagon layer, grapheme, by F.
4) The electronic structure has been calculated as a function of the ribbon model structure of grapheme layer. And also specific small angle X-ray diffraction was successfully applied for characterization method of nanocarbons.
5) The model of nano pore structure in porous carbons has been proposed, and their size and structure can be designed in relation with the size of solvated ions for advanced electric double layer capacitor. The results have been contributed to both in science as well as in technical point of view, for large scale application of EDLC.
6) The concept of nanocarbons started firstly from present project has been spread in world level in science community and such concept has been used in the conference..
