This study investigated the properties of mesocarbon anodes in the half-cell of sodium-ion batteries. The behavior of mesocarbon was examined using electrochemical methods. Cyclic voltammetry (CV) was applied with various scan rates to reveal the anodic-cathodic voltage and peak current. The CV profile allowed for predicting the energy storage mechanism of sodium ions in mesocarbon. The CV measurement of the half-cell Na | mesocarbon demonstrated the intercalation and de-intercalation of sodium ions in the graphene interlayer at 0.01 V and 0.12 V, respectively. Based on the Power law, the kinetics of sodium ion movement was controlled by the diffusion-dominant reaction. After 25 cycles, the electrochemical impedance spectroscopy (EIS) spectra exhibited increasing resistances in the solid-electrolyte interface (RSEI) and charge transfer (Rct), ranging from 53.8 to 65.6 Ω and 42.6 to 229 Ω, respectively. Considering the charge/discharge rate capability in the first five cycles, the mesocarbon could deliver a specific capacity of discharge of 42 mAh/g at 0.1 C and retain 73% of its capacity after 25 cycles.
