  • A facile scalable synthesis of Ti02/C nanohybrids inspired by polymeric dental
    restorative materials has been developed, which creates ultra-small Ti02 nanoparticles
    homogeneously embedded in the carbon matrix. The average size of the nanoparticles
    is tuned between about 1 nm and 5 nm with the carbon content systematically
    increased from  0%to 65%.Imaging analysis and scattering technique have been
    applied to investigate the morphology of the Ti02 nanoparticles. The composition,
    nature of carbon matrix, crystallinity, and tap density of the Ti02/C nanohybrids have
    been studied. The application of the Ti02/C nanohybrids as lithium-ion battery anode
    is demonstrated.  Unusual discharge/charge profiles have been exhibited, where
    characteristic  discharge/charge  plateaus  of  crystalline  Ti02  are  significantly
    diminished. The tap density, cyclic capacities, and rate performance at high current
    densities (10 C, 20 C) of the TiOz/C nanohybrid anodes have been effectively
    improved compared to the bare carbon anode and the Ti02/C nanohybrids with larger
    particle size.
