Synthesis of Porous Carbon Materials Based on Reduced Graphene Oxide and Their Application in Lithium-Sulfur Batteries

Abstract

In this paper, MnO2/reduced graphene oxide (rGO) composite is prepared by a one-step hydrothermal method. The extraordinary structure provides MnO2/rGO composite with a large specific surface area and numerous channels for rapid diffusion of electrolyte ions, electron transport, and high conductivity due to the presence of rGO. Electrochemical results demonstrate that MnO2/rGO composite has good capacitive performance with a specific capacitance of 794 mAh·g-1 at a current of 0.1 mA.
