MXene and cotton-derived biochar were prepared by modified acid etching and high-temperature carbonization, respectively. Based on their characterization with SEM and XRD, a suitable mass ratio of MXene to the cotton-derived biochar for modification purpose was determined. The electrochemical properties of the materials were further explored by performing charge-discharge and cyclic voltammetry tests, and using electrochemical impedance spectroscopy. It is shown that the MXene delivers an initial discharge specific capacity of 434.3 mAh/g at a current density of 0.1 A/g. A composite with MXene and cotton-derived biochar in a mass ratio of 1∶3 can deliver an initial discharge specific capacity of 1 486.60 mAh/g at 0.1 A/g, exhibiting excellent cycling performance, rate capability and electrical conductivity, which can provide a reference for application of MXene in lithium-ion batteries.
