A nanocomposite between carbon and nanotube Formula (CNTT) was prepared by addition of activated carbon during hydrothermal treatment of Formula and following high-temperature calcinations. From morphological analysis using a scanning electron microscope, transmission electron microscope, and Formula sorption profiles, it was revealed that nanotube Formula 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.​
