Technical Field
The invention belongs to the technical field of preparation of nano materials, and particularly relates to a preparation method and application of an MXene derivative/metal nano composite material.
Background
With the rapid development and application of modern electronic devices, especially portable electronic devices and electric vehicles, there is an increasing demand for low-cost, high-performance and environmentally-friendly energy storage devices. The super capacitor has attracted people's attention in the last decade because of its high power density, fast charge and discharge rate, high cycle stability and other characteristics. An emerging two-dimensional MXene material has been receiving attention since the advent. However, the interlayer structure of the MXene sheets is difficult to support by weak van der Waals force, and the MXene sheets are easy to stack in the preparation process of the electrode material, so that the performance of the electrode is greatly influenced. In addition, MXene materials have limited applications in many areas due to their generally low mass to capacitance.
