Title:

SULPHUR-CARBON COMPOSITE AND PREPARATION METHOD THEREFOR, ELECTRODE MATERIAL AND LITHIUM-SULPHUR BATTERY CONTAINING SULPHUR-CARBON COMPOSITE

Document Type and Number:

WIPO Patent Application WO/2017/143549

Kind Code:

A1

Abstract:

Provided are a sulphur-carbon composite for a lithium-sulphur battery and a preparation method therefor, and an electrode material and a lithium-sulphur battery containing the sulphur-carbon composite. The composite comprises carbon nanoparticles, sulphur loaded in the carbon nanoparticles and a silicon dioxide template agent remaining in the carbon nanoparticles, wherein, by mass percent, the sulphur content is 40%-70% and the content of the silicon dioxide template agent is 0.3%-3%. The residual silicon dioxide template agent is dispersed in the carbon nanoparticles so as to reduce the pore diameter of the carbon nanoparticles.
