| Abstract: | In this paper, MnO2/MXene–Ti3C2 composites with different molar ratios were successfully prepared by a one-step hydro-thermal method, and the optimum proportion was confirmed by XRD and SEM comparative analysis. The optimum proportion of MnO2/MXene–Ti3C2 composites and MnO2 was used as a cathode material for magnesium batteries to carry out the electrochemical performance test. The results showed that the charge–discharge capacity of the MnO2/MXene–Ti3C2 composite was up to 105 mA h g−1, much higher than that of MnO2 (64 mA h g−1), and meanwhile it had good rate performance. At the same time, this also opened up the application of MXene–Ti3C2, a new two-dimensional material, in the field of battery electrode materials.In this paper, MnO2/MXene–Ti3C2 composites with different molar ratios were successfully prepared by a one-step hydro-thermal method, and the optimum proportion was confirmed by XRD and SEM comparative analysis. |
