“…Analogous methodology was applied in the fabrication of sulfur‐confined hollow carbon structures using different templates from silica such as TiO 2 and SnO 2 . Nersisyan et al developed a creative combustion‐mediated approach to yield hollow carbon nanospheres with controllable shell thickness. First, they selected sodium azide (NaN 3 ), and halogen polymer, as raw materials.…”

Lithium-sulfur batteries (LSBs) are regarded as a new kind of energy storage device due to their remarkable theoretical energy density. However, some issues, such as the low conductivity and the large volume variation of sulfur, as well as the formation of polysulfides during cycling, are yet to be addressed before LSBs can become an actual reality. Here, presented is a comprehensive overview illustrating the techniques capable of mitigating these undesirable problems together with the electrochemical performances associated to the different proposed solutions. In particular, the analysis is organized by separately addressing cathode, anode, separator, and electrolyte. Furthermore, to better understand the chemistry and failure mechanisms of LSBs, important characterization techniques applied to energy storage systems are reviewed. Similarly, considerations on the theoretical approaches used in the energy storage field are provided, as they can become the key tool for the design of the next generation LSBs. Afterward, the state of the art of LSBs technology is presented from a geopolitical perspective by comparing the results achieved in this field by the main world actors, namely Asia, North America, and Europe. Finally, this review is concluded with the application status of LSBs technology, and its prospects are offered.nonrenewable sources depletion and environment pollution (global warming and air/water quality). In particular, the abundant use of fossil fuels (especially coal and oil) is origin of many medical problems all over the world resulting in a constant rising of health-care national systems expenses. In this regard, especially solar and wind based energy sources, have been demonstrated to represent a valid alternative to fossil fuels. However, their energy instability related to a nonconstant presence of sun/wind, determines an intermittent energy production which severely jeopardize a stable and reliable energy supply to the grid. In order to mitigate and possibly even to completely solve this issue, a feasible solution is to couple solar/wind energy generators with energy storage devices. The presence of these systems would indeed allow the release of the produced energy into the grid at the right time, therefore avoiding any instability or even grid failure. Among the available energy storage devices, secondary batteries represent surely a valid choice owing to the abundant research in this field and to the number of applications already exploiting batteries as the main energy source. In this regard, here we recall lead-acid, nickel-cadmium and His work mainly aims in modeling and experimentally validating complex systems at the micro/nanoscale with strong emphasis on the final device. In particular, his research themes focus on the integration of different physics (i.e., interdisciplinary) such as photonics, heat diffusion, electric charge/mass diffusion, and mechanicaldeformation toward the development of innovative devices for energy manipulation (harvesting and storage).nitrogen element coul...

“…6 e), while the corresponding value of the N-CNSs/S electrode is 1250 mAh g −1 with a capacity retention of 76%. The obtained values of Ni@N-CNSs/S electrode are also much better than that of other carbon/S powder electrodes (e.g., hollow carbon nanospheres/S [ 37 ], carbon spheres/S [ 39 ], S/C nanospheres [ 36 , 40 ]) (Table S1). As for the Coulombic Efficiency (CE) analysis, after 200 cycles, the CE value of Ni@N-CNSs/S electrode maintains 98.5%, higher than that of N-CNSs/S (97.8%).…”

“…Among the explored carbon hosts, carbon nanospheres (CNSs) have been widely studied as active hosts for sulfur. To date, different carbon nanospheres have been fabricated by different methods including hydrothermal synthesis with sacrificial silica/polystyrene templates, glucose decomposition [ 32 , 33 ], thermal conversion via ZIF-8 template [ 34 ], and polyaniline-co-polypyrrole [ 35 ], combustion method [ 36 ], and sodium dodecyl sulfate-assisted self-assembly method [ 37 ]. However, the obtained carbon spheres are powder materials and need combining with additives and polymer binders to form working electrode.…”

“…Tremendous efforts have been devoted to solve these scientific issues in Li-S cells by holding sulfur in various composites with special structures or exploiting new electrolytes. Although significant progress has been made in the utilization of elemental sulfur and the cyclic stability, the synthetic methods are usually relatively complex, which not only need a variety of additives but also have a higher requirements for the manufacturing processes (Xiong et al, 2012 ; Huang et al, 2013 ; Wang et al, 2013 ; Hu et al, 2014 ; Zhang et al, 2014 ; Deng et al, 2015 ; Lee et al, 2015 ; Liu et al, 2016 ; Lu et al, 2016 ; Nersisyan et al, 2016 ; Yang et al, 2016 ). Alternatively, modifying the commercial separators have been proved to be a facile and commendable strategy to improve the electrochemical performance through effective regulation of polysulfide shuttle (Chung and Manthiram, 2014a , b ; Li G. C. et al, 2015 ; Balach et al, 2016 ; Conder et al, 2016 ; Fan et al, 2016 ).…”

To inhibit the polysulfide-diffusion in lithium sulfur (Li-S) batteries and improve the electrochemical properties, the commercial polypropylene (PP) was decorated by an active carbon (AC) coating with lots of electronegative oxygenic functional group of –OH. Owing to the strong adsorption of AC and the electrostatic repulsion between the –OH and negatively charged polysulfide ions, the Li-S batteries demonstrated a high initial discharge capacity of 1,656 mAh g−1 (approximately 99% utilization of sulfur) and the capacity can still remain at 830 mAh g−1 after 100 cycles at 0.2 C. Moreover, when the rate was increased to 1 C, the batteries could also possess a discharge capacity of 1,143 mAh g−1. The encouraging cycling stability make clear that this facile approach can successfully restrain the shuttle effect of polysulfides and make further progress to the practical application of Li-S batteries.
