Nanocarbon such as carbon nanotubes (CNTs) and carbon nanospheres (CNSs) have excellent electrical properties so that they can be used to substitute graphite as anode material for lithium-ion battery. The use of nanocarbon as anode material provides a short path for the ion and electron movement in electrodes. Therefore, the energy density of the battery can be improved. In this research, the production of CNT and CNS was carried out through spray nebulization at 650, 700, and 750oC with 15, 30, and 45 min reaction time in the presence of ferrocene as catalyst with the concentration of 0.015; 0.02; 0.025 g/ml of hydrocarbon. Turpentine oil, an environmentally friendly precursor, was used as carbon source. The materials obtained was physically characterized by SEM, TEM, Raman spectroscopy, X-ray diffraction, and X-ray photoelectron spectroscopy. Meanwhile, the electrochemical properties will be analized by plotting charge-discharge capacity vs cycle number and electrochemical impedance spectroscopy.
