Title:
SULFUR-TRIAZINE POLYMER AND LITHIUM-SULFUR BATTERY THAT CONTAINS SAME AS POSITIVE ELECTRODE AND THUS CAN BE USED IN LEAN ELECTROLYTE
Document Type and Number:
WIPO Patent Application WO/2024/076045
Kind Code:
A1
Abstract:
The present invention relates to a sulfur-triazine polymer and a lithium-sulfur battery that contains same as a positive electrode and thus can be used in a lean electrolyte, and, more particularly, to a sulfur-triazine polymer prepared by covalently grafting sulfur to triazine, and a lithium-sulfur battery that contains same in the positive electrode and thus exhibits high performance even in a lean electrolyte.
