“…Among carbon materials, graphene, a two‐dimensional (2D) honeycomb sp 2 carbon lattice, is served as one promising host for wrapping or anchoring sulfur to fabricate excellent carbon/sulfur composite cathodes for LSBs . It can sever as an effective interlayer between cathode material with separator, fabricate the hybrid system as cathode materials, combine with heteroatom as electrode materials, and so on for emerging energy storage devices.…”

Lithium‐sulfur battery as one of the most promising and attractive candidate among the emerging electrical energy storage has attracted enormous attentions. It has superior characteristics of high specific energy density (2600 Wh kg−1) and high theoretical specific capacity (1675 mAh g−1), which is equal to 3–5 times of lithium‐ion batteries, and more closed to the requirement of the pure electric vehicles and hybrid electric vehicles. Furthermore, sulfur element is inexpensive, naturally abundant, and environmentally friendly. However, the commercial application of lithium‐sulfur batteries (LSBs) still faces some major technical obstacles such as the low electrical conductivity of sulfur, the shuttle effect of polysulfides, and the drastic volume expansion during charge/discharge process. In this review paper, we focus on some of the effective strategies in boosting the electrochemical performance of LSBs through the development of sulfur/carbon composite electrode materials, including the use of porous carbons, carbon nanotubes/fibers, and graphene. The integration of carbon materials and sulfur can efficiently improve the utilization of active materials, enhance the conductivity of cathode materials, and provide a polysulfides barrier. Simultaneously, the challenges and prospects on LSBs in the near future are also presented and discussed.

“…From the early 2000's to 2017, the number and diversity of potential applications for these materials grew considerably; applications investigated include substrates for supercapacitors [26][27][28][29][30][31][32], photocatalysis [33][34][35][36][37][38][39][40][41][42][43], liquid chromatography [44], sensors (e.g. pressure [45][46][47], biological [48] and gas [49][50][51]), and batteries [52][53][54][55][56][57][58][59][60][61][62]; biomaterials remain the most extensively investigated application. Dense composite materials may also be fabricated by infiltrating freeze-cast skeletons with a secondary phase.…”

“…The D band is related to the irregular arrangement of the sample, and the G band is related to the sp 2 hybridization degree of the carbon atoms. , The calculated I D / I G ratios for graphite oxide and 1D-GNS are 0.78 and 0.85, respectively. The elevated I D / I G value of 1D-GNS indicates the increase of the disorder extent during the formation process of the 1D-GNS. , Figure F shows the curves of the N 2 adsorption/desorption isotherm and the pore size distribution of 1D-GNS.

Graphene nanoscroll has received enormous interest due to its potential applications in various fields. However, in practice there still remains a challenge toward cost-efficiency and scale-up production with the existing advanced experimental techniques. Herein, we report an integration methodology to construct a one-dimensional graphene nanoscroll (1D-GNS) from a two-dimensional graphene nanosheet (2D-rGO) via an ingenious template-directed synthesis approach, in which Na2SO4 was used as a sacrificial template for the first time. Na2SO4 was first generated on the surface of reduced graphene oxide (rGO) nanosheets by a combination of antisolvent self-assembly and heat treatment under moderate temperature, in sequence, to shape and maintain the 2D-rGO architecture into an rGO@Na2SO4 composite, which was then immediately quenched into water to dissolve the Na2SO4 template and meanwhile roll up the 2D graphene nanosheets into 1D nanoscrolls spontaneously, followed by a final thermal reduction to reduce the oxygenous groups. The crimping behavior of the 1D-GNS can be conducted by varying the heat-treatment temperature during the quenching process. The as-synthesized 1D-GNS gives quite good electrochemical stability when evaluated as an anode material in a Li-ion battery. This interesting methodology provides an avenue to design and fabricate other scroll-structured nanoarchitectures.
