| Summary: | Abstract In this article, we have investigated the impact of various aqueous electrolytes on the electrochemical performance of Ti3C2Tx-BiFeO3 (MXene-BFO) nanocomposites for energy storage applications. Structural and morphological characterizations were performed utilizing X-ray diffraction (XRD), Raman spectroscopy, scanning electron microscopy (SEM), and energy-dispersive spectroscopy (EDS). The study focused on four electrolytes: NaOH, Na2SO4, MgSO4, and LiCl, exploring their interactions with the MXene-BFO nanocomposites system. Electrochemical analyses, including cyclic voltammetry (CV), galvanostatic charge-discharge (GCD) tests, and electrochemical impedance spectroscopy (EIS), were conducted to evaluate specific capacitance, potential windows, and impedance characteristics. Notably, the nanocomposite demonstrated optimal pseudocapacitive performance in 1 M NaOH, exhibiting a specific capacitance of 532 F/g at a scan rate of 2 mV/sec, and achieved an energy density of 53.8 Wh/kg and a power density of 1.62 kW/kg at a current density of 1 A/g. This electrolyte also displayed low electrolyte resistance (2.9 Ω) and favorable charge transfer resistance (1.5 Ω), with significant coulombic efficiency over 10,000 charge-discharge cycles. These findings underscore the potential of 1 M NaOH as a highly effective electrolyte for enhancing the performance of MXene-BFO nanocomposites-based supercapacitors, offering substantial insights into the optimization of electrode-electrolyte interactions in advanced energy storage systems. |
