Outline of Final Research Achievements

Almost perfect embedding of SnO2 nanocrystallites in carbon nanopores was achieved by in situ synthesis using vaporized SnCl2 and silica opal-derived nanoporous carbons. It was found that the reversibility of electrochemical reactions of SnO2 is enhanced by the confinement in carbon nanopores and excellent charge-discharge cycleablity is achieved by the regulation of carbon nanospace. The detailed investigations on the SnO2/nanoporous carbon composites with systematically controlled pore size and SnO2-loading amount disclosed that the capacity retention was extremely enhanced at lower pore volume filling fraction of SnO2 than the theoretical value taking into account of full volume expansion for conversion and alloying reactions.
We also succeeded to synthesize a FeF3/nanosporous carbon.
