Abstract
The ability of lithium-ion diffusion in carbon nanobeads (CNBs) was investigated by the microelectrode method [cyclic voltammetry, constant current charge/discharge, potential step, and potentiostatic intermittent titration technique (PITT)]. CNBs showed high rate discharge capacities of over 1000 C. CNB heat-treated at 1000, 1500, and showed a higher charge ability than . The lithium-ion diffusion coefficient in CNBs was investigated by PITT. was different in the intercalation and deintercalation directions in 1000, 1200, and CNBs. of the intercalation and the deintercalation showed different potential dependencies. The heat-treated CNB showed the highest in the direction of intercalation.
