Abstract
The present invention discloses a tellurium-doped MXene composite material and a preparation method thereof, comprising the following steps: (1) adding MXene and a tellurium source into a dispersant to prepare a dispersion, and then stirring the dispersion; (2) heating the dispersion, reacting, and then cooling; (3) centrifuging the product obtained in the step (2), then washing and drying under vacuum; and (4) placing the dry product obtained in the step (3) into a corundum ark, and then transferring into a tubular furnace, heating under the protection of inert gas, retaining the temperature, and then cooling to obtain the tellurium-doped MXene composite material. The composite material prepared by the present invention can be used as a cathode of a potassium ion battery, which increases the interlamellar spacing, and optimizes an ion diffusion channel, so that the electrochemical performance of the potassium ion battery is improved.
