Outline of Final Research Achievements |
Some microporous carbons showed extremely high specific capacitance although the pore size was close to or smaller than the size of solvated ions in bulk solution. We have demonstrated that the enhancement of EDLC performance was caused by an accumulation of partially desolvated ions to form a compressed electric double-layer in the micropores. We have also successfully developed novel nanocomposites of Li2MnSiO4/carbon and Si/nanoporous carbon, which show high capacity and good cycleabiliy. The relationship between the charge-discharge properties and nanocomposite structure was investigated in detail.
