Title:
CONFINEMENT SILICON DIOXIDE/MULTI-WALLED CARBON NANOTUBE COMPOSITE MATERIAL, AND PREPARATION METHOD AND USE THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/116943
Kind Code:
A1
Abstract:
The invention relates to a confinement silicon dioxide/multi-walled carbon nanotube composite material, and a preparation method and use therefor. The method comprises the following steps: S1, dispersing multi-walled carbon nanotubes in a methyl substituted benzene solvent, and carrying out ultrasonic treatment for 10 minutes at room temperature; S2, after finishing the ultrasonic treatment, adding silicon tetrachloride liquid into the multi-walled carbon nanotube/xylene turbid liquid, and carrying out ultrasonic treatment for 10 minutes at room temperature; S3, heating the mixture in an oil bath to 145 °C, and performing backflow operation; S4, after finishing the reaction, free cooling to room temperature, and centrifuging, washing and drying the obtained solid to obtain a dried sample, thereby obtaining a confinement silicon dioxide/multi-walled carbon nanotube composite material. The confinement silicon dioxide/multi-walled carbon nanotube composite material has excellent charge-discharge rate performance and cycle stability, and has great application potential and industrial value.
