Outline of Final Research Achievements

The increasing importance of global environmental deterioration is the major factor prompting the renewable electricity generation such as solar photovoltaics and wind power. For the efficient utilization of renewable energy, innovative technology developments of electric energy storages (EES) are indispensable as well as the electric generation technology. Our project pursues the realization of novel high-power EES which possesses both of superior energy density to electric double layer capacitors (EDLC) and high power density far above the standard value of conventional lithium ion batteries (LIB). We have successfully synthesized the nano-nano composites with an ultrafast electrochemical responses as an active materials for the next generation EES by nano-fusion of LIB technology (nanoparticles of LIB electrode) and EDLC technology (nano carbons).
