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.
本文采用一步水热法成功制备了不同摩尔比的MnO/MXene-TiC复合材料，并通过XRD和SEM对比分析确定了最佳比例。将MnO/MXene-TiC复合材料和MnO的最佳比例用作镁电池的阴极材料进行电化学性能测试。结果表明，MnO/MXene-TiC复合材料的充放电容量高达105 mA h g，远高于MnO（64 mA h g），同时具有良好的倍率性能。同时，这也开辟了新型二维材料MXene-TiC在电池电极材料领域的应用。
