Study on MXene-supported Layered TiS2 as Cathode materials for Magnesium batteries

Abstract

TiS2/MXene composites with different molar ratio were successfully prepared by one-step hydro-thermal method, and the optimal proportion was confirmed by characterization. The electrochemical performance of TiS2/MXene composite and TiS2 as magnesium battery cathode were tested. The test results show that at the current density of 50 mA/g, TiS2/MXene composite exhibits enhanced capacities of 97 niAli/g. Compared with pure TiS2, it has higher charge-discharge capacity and better cycle performance. At the same time, the introduction of new MXene materials also provides a new idea for the study of new anode materials for magnesium batteries.
