Abstract

The invention provides a lamellar MXene material preparation method and a battery material thereof. The method includes: directly forming a raw material mixture according to a stoichiometric ratio, wherein a structural formula of a multi-element conductive ceramic material is (M1-xYx)n+1ACn, n is equal to 1, 2 or 3, x is greater than or equal to 0 and less than or equal to 1, M and Y are transition metal elements, A refers to an IIIA or IVA element with an atomic number greater than 13, and C refers to carbon; in an inert atmosphere, subjecting the raw material mixture to reaction in molten salt, and cooling after reaction is finished; removing the molten salt from a product mixture to obtain the multi-element conductive ceramic material; subjecting A atoms in the conductive ceramic material to corrosion to obtain a lamellar MXene material. At least one of problems including high synthesis temperature, complexity in preparation process and equipment, high cost and the like of an existing MXene material can be solved, and the method has advantages of quickness, high efficiency, energy saving, environmental friendliness, low cost, easiness in implementation of large-scale productionand the like.

Description

technical field

[0001] The invention relates to the technical field of preparation of conductive ceramic materials, in particular to a method for preparing a sheet-like MXene material with low energy consumption and low cost, and an energy storage material containing the sheet-like MXene material. Background technique

[0002] Usually, materials involve a wide range of fields. For example, the industrial and agricultural construction of a country, the construction of national defense, and the improvement of people's living standards are all closely related to materials. Therefore, people regard materials as one of the three pillars of modern civilization.

[0003] In recent years, a class of ternary ceramics with a layered structure has attracted the attention of material science researchers at home and abroad due to the excellent properties of both ceramics and metals. This machinable conductive ceramic is a hexagonal close-packed carbide or nitride with obvious anisotropy....
