Abstract
This work investigated the effect of super p on the specific capacity of MXene-based rechargeable Li-O2battery. It was observed that by changing the ratio of super P from 10% to 30%, the specific discharge capacity of the lithium-oxygen battery has been enhanced from 396 mAhg-1 to 1116 mAhg-1 in the 1st cycle at the current density of 100 mAg-1. To analyze the structure of synthesized MXene, techniques such as scanning electron microscopy (SEM), X-ray diffraction (XRD), Raman spectroscopy, and Fourier transform infrared (FTIR) spectroscopy were employed. The electrochemical properties of the fabricated electrodes were assessed using cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS). Based on the analysis, the synergistic effect between MXene and Super P results in a higher capacity for the fabricated cell.
