“…The strategy being implemented to improve the performance is to add other components that increase the conductivity and/or the ability to trap polysuldes. Conductive organic (polymers [82][83][84] ) and inorganic (Ni nanoparticles, graphene nanosheets [85][86][87][88] ) additives in nature have been tested. On the other hand, different transition metal compounds, such as Fe 3 C, 89 MS 2 (M ¼ Co, Ni), 80,90 93 and NiAl-LDH, 94 have been examined to enhance the LiPSs absorption.…”

“…Aside from individual polymeric modification, combination with other materials is considered a valuable strategy for the design of efficient sulfur cathodes. For example, by inducing homogeneous PANI formation on the surface of sulfur/carbon core/shell structures, stable SEI and fast charge transport can be achieved due to the appearance of the modified polar interfaces . In particular, 3D CNF/S/PANI prepared by in situ polymerization on 3D sulfur/carbon nanofibers was found to facilitate the electron transfer between the insulating S and double conductive matrices and, at the same time, to help to accommodate the volume change of sulfur during cycling in order to maintain the structural integrity of the cathode …”

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...

To solve the slow kinetics of polysulfide conversion reaction in Li-S battery, many transition metal nitrides were developed for sulfur hosts. Herein, novel polyaniline-coated porous vanadium nitride (VN) microrods were synthesized via a calcination, washing and polyaniline-coating process, which served as sulfur host for Li-S battery exhibited high electrochemical performance. The porous VN microrods with high specific surface area provided enough interspace to overcome the volume change of the cathode. The outer layer of polyaniline as a conductive shell enhanced the cathode conductivity, effectively blocked the shuttle effect of polysulfides, thus improving the cycling capacity of Li-S battery. The cathode exhibited an initial capacity of 1007 mAh g−1 at 0.5 A g−1, and the reversible capacity remained at 735 mAh g−1 over 150 cycles.
