Abstract

The invention discloses Ti3C2Mxene with a three-dimensional fold structure as well as a preparation method and application of the Ti3C2Mxene. The preparation method comprises the following steps: (S1) obtaining dispersion liquid of the Ti3C2Mxene; and (S2) mixing a cationic surface active agent with the dispersion liquid of the Ti3C2MXene, and carrying out a reaction, so as to obtain the Ti3C2MXene with the three-dimensional fold structure. Aiming at the problems of poor conductivity, volume change and the like of 2H-MoS2, 1T-MoS2 is compounded with three-dimensional fold structure Ti3C2Mxene, so that the conductivity of the material is improved, and the stacking and agglomeration of the material are inhibited.

Description

technical field

[0001] The present application relates to a three-dimensional wrinkled structure Ti 3 C 2 Mxene and its preparation method and application belong to the field of composite materials. Background technique

[0002] Lithium-ion batteries have been widely used due to their high energy density and power density, but with the rapid development of science and technology, people's demand for energy is also increasing rapidly. The current commercial carbon-based anodes are increasingly unable to meet the demand for high energy density in the future. Therefore, it is urgent to develop and design a high-cycle anode material to improve the lithium storage capacity of batteries.

[0003] In recent years, transition metal chalcogenides have attracted the attention of researchers due to their high theoretical specific capacity. Molybdenum disulfide (MoS 2 ), as a typical transition metal chalcogenide, benefits from a two-dimensional layered structure and possesses many...
