Ultrathin covalent organic polymer-decorated reduced graphene oxide for enhanced sulfur conversion kinetics in Li–S batteries

Abstract

An ultrathin covalent organic polymer catalyst supported on reduced graphene oxide (COP–rGO) is prepared as an effective catalyst for Li–S batteries, and it displays enhanced catalytic ability for the sulfur conversion reaction. A Li–S cell with the COP–rGO catalyst can deliver excellent electrochemical performance.
