Title:
POSITIVE ELECTRODE FOR LITHIUM-SULFUR BATTERY, METHOD FOR MANUFACTURING SAME, AND LITHIUM-SULFUR BATTERY INCLUDING SAME
Document Type and Number:
WIPO Patent Application WO/2023/128592
Kind Code:
A1
Abstract:
The present invention pertains to a positive electrode for a lithium-sulfur battery, the positive electrode comprising a positive electrode active material and a binder, wherein the positive electrode active material includes a sulfur-containing material, graphene, and carbon nanotubes (CNTs). The carbon nanotubes are first mixed with the graphene and provided in a network form, after which the sulfur-containing material is added so as to settle inside the network form.
