Title:
METHOD FOR PREPARING COMPOSITE MATERIAL OF METAL-ORGANIC FRAMEWORKS AND CARBON NANOTUBES
Document Type and Number:
WIPO Patent Application WO/2020/006788
Kind Code:
A1
Abstract:
Provided is a method for preparing a composite material of metal-organic frameworks and carbon nanotubes, the method comprising the following steps: 1) weighing and obtaining trimesic acid and
ceric ammonium nitrate in a molar ratio of 1:1, adding a solvent mixture of an organic solvent, N,N‑dimethylformamide, and water in a ratio of 5:1, and mixing the same to obtain a mixed solution; 2) placing the mixed solution in an oil bath at a temperature of 80-120℃ for 30 minutes, and obtaining a gray powder; 3) washing the gray powder with N,N‑dimethylformamide and absolute methanol; and 4) drying after the washing to obtain a composite material of nano-metal-organic frameworks and carbon nanotubes. Coatings and separator membranes of the composite material of metal-organic frameworks and carbon nanotubes prepared by the method are applicable to lithium-sulfur batteries, and effectively suppress the shuttle effect, thereby improving the cycle stability and specific capacity of batteries.
