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, solar cell, wind power, hybrid/electric vehicle with large scale secondary battery devices is now considered to be a key technology. Researches on the  high capacity electrodes with rare metal free are ongoing via advanced nanoscience and nanotechnology of materials.

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 novel electrode materials via nanosize effects of functional materials. Based on interdisciplinary science, advanced energy conversion devices and systems are investigated.
