Hierarchical Sulfur‐Based Cathode Materials with Long

Composite materials of porous pyrolyzed polyacrylonitrile–sulfurgraphene nanosheet (pPAN–SGNS) are fabricated through a bottom‐up strategy. Microspherical particles are formed by spray drying of a mixed aqueous colloid of PAN nanoparticles and graphene nanosheets, followed by a simple heat treatment with elemental sulfur. The pPAN–S primary nanoparticles are wrapped

To investigate the influence of sulfur, a series of sulfur-doped graphene materials with varying sulfur contents ranging from 0.35 to 3.95 at% are applied as platinum nanowire catalyst supports. Based on the physico-chemical characterizations, electrochemical measurements and density functional theory (DFT) calculations, we find that the amount of sulfur significantly affects the

A novel lithium/sulfur battery based on sulfur/graphene

A novel sulfur/graphene nanosheet (S/GNS) composite was prepared via a simple ball milling of sulfur with commercial multi-layer graphene nanosheet, followed by a heat treatment. High-resolution transmission and scanning electronic microscopy observations showed the formation of irregularly interlaced nanosheet-like structure consisting of graphene with uniform sulfur coating on its surface.

And then, sulfur particles were dispersed into the PDDA-GO composites by mixing in the CS2 solvent. It is expected the PDDA-GO/S composites show the limited release of polysulfides due to the fact that it can provide high surface area, because conducting polymer can be used as spacer between graphene
