Abstract
A nanocomposite between carbon and nanotube TiO2 (CNTT) was prepared by addition of activated carbon during hydrothermal
treatment of TiO2 and following high-temperature calcinations. From morphological analysis using a scanning electron microscope,
transmission electron microscope, and N2 sorption profiles, it was revealed that nanotube TiO2 was homogeneously
dispersed with carbon in nanoscale for CNTT materials. When applied into the anode in a lithium-ion battery, CNTT electrodes
displayed higher cyclability and better rate capability. From ac-impedance measurement, the total resistance was smaller in the
CNTT electrode due to a homogeneously dispersed carbon in nanoscale and a more porous structure.
