Title:
COMPOSITE MATERIAL, PREPARATION METHOD THEREFOR AND USE THEREOF AS ELECTRODE MATERIAL
Document Type and Number:
WIPO Patent Application WO/2021/077884
Kind Code:
A1
Abstract:
Disclosed are a composite material, a preparation method therefor and an application thereof. The preparation method for the composite material comprises the following steps: mixing MXene and a transition metal salt solution, and then sequentially performing filtering and drying treatment to obtain transition metal salt loaded MXene; performing high-temperature chemical vapor deposition on the transition metal salt loaded MXene and a carbon source to obtain a first product; performing acid treatment on the first product; performing high-temperature chemical vapor deposition on the first product subjected to the acid treatment and a silicon source to obtain a second product; and performing high-temperature chemical vapor deposition on the second product and the carbon source to obtain the composite material. According to the preparation method, the MXene, the carbon source and the silicon source can be effectively combined, so that the capacity, rate capability and cycling stability of a lithium-ion battery can be greatly improved.
