Abstract: A method for preparing a sulfur-doped ReSe 2 /MXene composite material, comprising: using MXene as a main substrate; loading synthesized ReSe 2  on MXene; doping a ReSe 2 /MXene complex with a sulfur element; and preparing a sulfur-doped ReSe 2 /MXene composite material by means of a heat treatment reaction. The sulfur-doped ReSe2/MXene composite material has good conductivity, an increased interlayer spacing, and a large specific surface area. The specific layered structure of MXene effectively mitigates the problems such as electrical performance degradation and structural collapse caused by the agglomeration or volume expansion of negative electrode materials during the cycle of charging and discharging.; the load of ReSe 2  effectively increases the interlayer spacing and increases the specific surface area; furthermore, due to doping of the sulfur element, more active sites and vacancies of the ReSe 2 /MXene composite material are exposed, thereby improving the potassium storage performance of the material. MXene, ReSe 2 , and sulfur atoms can overcome respective defects and deficiencies, and have a synergistic effect, thereby improving, to the greatest extent, the potassium storage performance of the composite material, and properties such as the specific capacity, charging and discharging stability, and the electron transfer rate. Moreover, the preparation process is simple, and the performance is controllable.
