| 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 2000°C showed a higher charge ability than 2800°C. The lithium-ion diffusion coefficient (DLi+) in CNBs was investigated by PITT. DLi+ was different in the intercalation and deintercalation directions in 1000, 1200, and 1500°C CNBs. DLi+ of the intercalation and the deintercalation showed different potential dependencies. The 1200°C heat-treated CNB showed the highest DLi+ in the direction of intercalation. |
