A simple approach to synthesize novel sulfur/graphene oxide/multiwalled carbon nanotube composite cathode for high performance lithium/sulfur batteries

摘要

A sulfur/graphene oxide/multiwalled carbon nanotube(S/GO/MWNT) composite was synthesized via a simpleultrasonic mixing method followed by heat treatment. By takingadvantage of this solution-based self-assembly synthesisroute, poisonous and noxious reagents and complicated fabricationprocesses are rendered unnecessary, thereby simplifyingits manufacturing and decreasing the cost of the finalproduct. Transmission and scanning electronic microscopyobservations indicated the formation of the threedimensionalinterconnected S/GO/MWNTcomposite throughthe environmentally friendly process...
