“…A copolymerization process could be realized by introducing various linker comonomers, and strong covalent bonds between carbon framework and sulfur guarantee the insolubility of polysulfides into liquid electrolytes, hence achieving high sulfur content and impressive electrochemical performance . Based on the categories of cross‐linking monomers, organosulfur composites could be classified into the following types: unsaturated hydrocarbons including alkene/alkyne (CC/CC), thiol (SH) and nitrile (CN) …”

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...

“…As described in the Introduction, the IV process is a synthetic method recently burst out in the literature. 9,[13][14][15][16][17][18][19][20][21][22][23][26][27][28][29][30] It allows to obtain polymers with a high sulfur content (from 50-90 wt%) with peculiar and intriguing properties, in particular very high refractive index and excellent transparency in the near infrared region, this making them appealing for photonic applications. We would like to further stress sulfur is a waste of oil and gas industry, thus making IV a strategy for recycling such elements to produce polymers for novel technological applications.…”

“…The reaction mixture was then cooled to 135 C (i.e., lower temperature but still at a molten state) and subjected to 7 mbar of pressure for 5 h, followed by an additional 2 h maintained at 75 C (i.e., solid phase) to distill p-cymene and other volatile byproducts before cooling to room temperature to yield the copolymeric product.
