| Outline of Final Research Achievements |
In this study, efficient production processes to prepare TiO2/C nanoparticles with a high TiO2 content and porous-carbon/TiO2 nanocomposites with a very small diameter of TiO2 nanoparticles were developed. The process to prepare the TiO2/C nanoparticles was performed by injecting a mixture of a Ti source and carbon source as liquid pulses into a heated reactor (ca. 800C) under a N2 flow. The obtained TiO2/C nanoparticles showed a high charge/discharge capacity as a TiO2 anode for high safe lithium-ion batteries. The process to prepare the porous-carbon/TiO2 nanocomposites were performed by injecting a Ti source as liquid pulses into a vacuuming heated reactor (200C) in which a porous-carbon was placed. The obtained porous-carbon/TiO2 nanocomposites showed a high rate-performance and cyclability, which are suitable for anodes in lithium-ion capacitors.
