研究の背景 Background


Low/Zero emission technology and renewable energy are becoming most important issues for realization of sustainable society. From viewpoints of energy supply system stabilization and protection of atmospheric pollution, hybrid/electric vehicle with large scale secondary battery devices is now considered to be a key technology. The developments of high capacity electrodes and advanced electrolytes can be attempted via a state of the art nanoscience and nanotechnology.

研究の目標 Outcome


Developments of advanced nanomaterials processing including supercritical fluid processes for producing nanoparticles, graphenes, nanosheets, and exploration of new electrode reaction as well as high capacity electrode active materials via nanosize effects. Based on interdisciplinary science, advanced energy conversion devices and systems are studied.
