Study on MnO(2)/MXene–Ti(3)C(2) composite materials as cathode materials for magnesium batteries

In this paper, MnO(2)/MXene–Ti(3)C(2) 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(2)/MXene–Ti(3)C(2) composites and MnO(2) 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(2)/MXene–Ti(3)C(2) composite was up to 105 mA h g(−1), much higher than that of MnO(2) (64 mA h g(−1)), and meanwhile it had good rate performance. At the same time, this also opened up the application of MXene–Ti(3)C(2), a new two-dimensional material, in the field of battery electrode materials.
