Reproduced material should be attributed as follows: If the material has been adapted instead of reproduced from the original RSC publication Lithium-sulfur (Li-S) batteries have received intensive investigations over the past decade due to its great potential as a high-capacity rechargeable battery technology (Ma et al., 2015; Manthiram et al., 2015; Wild et al., 2015; Fang et al., 2017; Peng et al., 2017; Zheng et al., 2017; Chen et al., 2018). To eliminate the potential safety hazard induced by the Li metal anode, high-capacity non-Li anodes, particularly silicon-based materials, have been sought as the alternative (Yang et al., 2010; Agostini et al., 2014; Cao et al., … For reproduction of material from all other RSC journals and books: For reproduction of material from all other RSC journals. Here we report a method of creating lithium sulfide–carbon composites as cathode materials, which can be paired with high-capacity anodes other than metallic lithium. of the whole article in a thesis or dissertation.

However, further progress on such batteries is hampered by their concomitant need for a metallic lithium anode, which introduces new challenges associated with uneven electrodeposition and lithium dendrite formation. is available on our Permission Requests page. to reproduce figures, diagrams etc. formally request permission using Copyright Clearance Center. it in a third party non-RSC publication you must S nanocrystals by reacting lithium sulfate with carbon precursors at high temperatures (820−900 °C) for >2 h.32,33 Elam et al. Li2S is typically produced by high temperature carbothermal reduction that creates powders, which then require extensive ball milling to produce the nano-sized materials desirable for battery applications. laa25@cornell.edu, b Lithium sulfide can be synthesized through carbothermic reduction of lithium sulfate according to the following equation: Li 2 SO 4 + x C → Li 2 S + x CO y (x = 1–4; y = 1–2) or in a thesis or dissertation provided that the correct acknowledgement is given If you are not the author of this article and you wish to reproduce material from Any queries (other than missing content) should be directed to the corresponding author for the article.

XX is the XXth reference in the list of references. contained in this article in third party publications The in situ synthesis approach allows facile, scalable synthesis of lithium sulfide–carbon composite materials that exhibit improved electrochemical properties. It can mitigate the volume expansion problem encountered by the sulfur cathode, besides, as a fully lithium‐inserted cathode, it can be paired with lithium‐free anodes or be assembled into anode‐free batteries. Corresponding authors, a Lithium sulfide is dispersed in a porous carbon matrix, which serves to improve its electrical conductivity and provides a framework for sequestration of sulfur and lithium polysulfides.

Lithium sulfide is dispersed in a porous carbon matrix, which serves to improve its electrical conductivity and provides a framework for sequestration of sulfur and lithium polysulfides. * In particular, the scalability of these methods is mentioned, and the costs of the resulted Li2S products are also estimated and compared to the currently used cathode materials for Li‐ion batteries. This review will provide useful guidance for the selection of practical Li2S synthesis routes.

We also investigate the effect of lithium polysulfides dissolved in the electrolyte on the stability and cycling behavior of Li2S–carbon composite cathodes. The lithium sulfide obtained according to the invention is used as a positive electrode composition in a galvanic element, for the synthesis of Li ion-conductive solids, in particular for the synthesis of glass, glass ceramics, or crystalline products, and particularly … Please check your email for instructions on resetting your password.

Herein, the preparation methods for Li2S nanoparticles are summarized, including laboratory synthesis methods and potential large‐scale preparation routes; traditional industrial synthesis methods for commercially available Li2S are also attached as references. Information about reproducing material from RSC articles with different licences However, commercially available Li2S powder delivers poor electrochemical performances due to the significant potential barrier during the first charging process, and therefore developing inexpensive synthesis route for nanosized Li2S with small diameter and low charging overpotential becomes the key to the construction of practical Li2S cathode.
