Description
In the present work, we prepared the porous carbon nanosphere from a biomass precursor (CNS) and made a composite of CNS with MXene (Ti3C2Tx) in various ratios. All the CNS:Mxene composites were electrochemical evaluated in three-electrode system in 3M KOH electrolyte solution with techniques, such as cyclic voltammetry (CV), galvanostatic chargedischarge (GCD), and electrochemical impedance spectroscopy (EIS). The 6:4 CNS:Ti3C2Tx MX ratio was found to exhibit excellent electrochemical performance with a higher specific capacitance of 527.5 Fg?1 at a current density of 0.25 Ag?1. A symmetric device study was carried out with 6:4 ratio of CNS:Ti3C2TxMX composite in S4R-SS316 type Swagelok cell. The device exhibited a maximum specific capacitance of 45.0 Fg?1 at a current density of 0.25 Ag?1, with a higher power density of 2500 Wkg?1 and very low energy density of 6.25Wh Kg?1. Thus, the electrochemical performance of the CNS/Ti3C2Tx MX composite exhibited a combined electrical conductivity from the MXene, and the porous nature and significant surface area from CNS, which improved the wettability implying the potential of CNS:MXene composites for enhanced energy storage. 2025 Wiley-VCH GmbH.
