Paper Details

In recent years, considerable effort has been made to improve the electrochemical performance of sulfurcathodes for the development of high-energy Li/S batteries. As a light- weight element, sulfur can react with metallic lithiumto form Li2S by a two-electron reaction, leading to a high theoretical capacity and energy density in lithium/sulfur batterysystem, almost one order of magnitude higher than that of conventional Li- ion batteries. Particular attention has beendevoted to the cycle stability and the utilization of a sulfur cathode by means of improving the conductivity of the sulfur andminimizing the solubility of the lithium polysulfides.Polymers are also a good alternative candidate for fabricatingsulfur/polymer composites, based on their conductivity and good compatibility with sulfur. Hence, in this work thepositiveelectrode with different sulfur ratios of sulfur/ poly (acrylonitrile) composites have been successfully prepared by asolid state reaction method. The XRD results confirm that the sulfur was completely dispersed as fine nano particles into thepolymer matrix. The SEM images clearly show the distributions of the particles with less cluster formation. Furthermore,PAN plays an important role in structural stability and chemical confinement settings for elemental sulfur with differentloading of the as prepared composites.
