Study on MnO/MXene-TiC composite materials as cathode materials for magnesium batteries.

In this paper, MnO/MXene-TiC 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 MnO/MXene-TiC composites and MnO 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 MnO/MXene-TiC composite was up to 105 mA h g, much higher than that of MnO (64 mA h g), and meanwhile it had good rate performance. At the same time, this also opened up the application of MXene-TiC, a new two-dimensional material, in the field of battery electrode materials.
