| Sumario: | Investigation of the physical and the electrochemical characterization of the sugarcane bagasse-derived activated carbon (SBAC) as a cathode material of lithium-ion capacitor (LIC) was reported in this article. The as-prepared SBAC was tested by BET, SEM, and EDS characterization. SBAC was assembled as cathode material and lithium titanate oxide (LTO) as anode material used to fabricate LIC in a CR2032 coin cell. The results show the as-synthesized SBAC has a microporous architecture with a surface area of 1,906 m2/g. The developed LIC exhibited an energy density of 28.4 Wh/kg and a power density of 1,770 W/kg, and a capacity retention of 75% at 100 cycles. In addition, this LIC has a specific capacitance of 141.8 mF/g. This study indicates that sugarcane bagasse is a prospective carbonaceous materials for the cathode of LIC. |
