en The enhancement of the specific capacity of Ti3C2Tx-based Li-O2 battery by adding super-p سیستم های ذخیره ساز انرژی Storage systems (battery, ultracapacitor, flywheel, etc) پژوهشي Research This study explored the impact of Super P on the specific capacity of MXene-based rechargeable Li-O₂ batteries. It was found that increasing the Super P ratio from 10% to 30% significantly improved the specific discharge capacity of the lithium-oxygen battery, rising from 396 mAh g⁻¹ to 1116 mAh g⁻¹ during the first cycle at a current density of 100 mA g⁻¹. To characterize the structure of the synthesized MXene, analytical techniques such as scanning electron microscopy (SEM), X-ray diffraction (XRD), Raman spectroscopy, and Fourier transform infrared (FTIR) spectroscopy were utilized. The electrochemical performance of the fabricated electrodes was evaluated using cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS). The findings indicate that the synergistic interaction between MXene and Super P contributes to the enhanced capacity of the fabricated cell.
