Title:
SULFUR-CARBON COMPOSITE, METHOD FOR PRODUCING SAME, AND LITHIUM SECONDARY BATTERY INCLUDING SAME
Document Type and Number:
WIPO Patent Application WO/2020/055017
Kind Code:
A1
Abstract:
The present invention pertains to: a sulfur-carbon composite; a method for producing same; a lithium secondary battery positive electrode including same; and a lithium secondary battery. The sulfur-carbon composite of the present invention is a sulfur-carbon composite that contains porous carbon, diisopropenylbenzene, and sulfur, wherein the diisopropenylbenzene and sulfur are supported in the pores and on the surface of the porous carbon, the pores of the porous carbon include first mesopores having a diameter of 2-8 nm and second mesopores having a diameter of 20-50 nm, and the porous carbon is a spherical particle having a particle diameter of 2-10 μm.
