Corresponding authors, a 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) Please enable JavaScript In the end, the commercially worthwhile research pathways for Li2S synthesis as well as the perspective on the practical production of Li2S are discussed. Lithium–sulfur batteries are among the most promising candidates for next-generation rechargeable lithium batteries in view of recent progress on sulfur–carbon composite cathodes. do not need to formally request permission to reproduce material contained in this Information about reproducing material from RSC articles with different licences The full text of this article hosted at iucr.org is unavailable due to technical difficulties. Reproduced material should be attributed as follows: If the material has been adapted instead of reproduced from the original RSC publication 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. article provided that the correct acknowledgement is given with the reproduced material. 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.

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 … synthesized amorphous Li 2 S nanofilms using a vapor-phase atomic layer deposition via alternating exposure to lithium tert-butoxide and hydrogen sulfide.34 However, it seems challenging for these methods to produce Li 2 This article has been accepted for publication and undergone full peer review but has not been through the copyediting, typesetting, pagination and proofreading process, which may lead to differences between this version and the Version of Record. 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., … S nanocrystals by reacting lithium sulfate with carbon precursors at high temperatures (820−900 °C) for >2 h.32,33 Elam et al. If you are the author of this article you still need to obtain permission to reproduce 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. Any queries (other than missing content) should be directed to the corresponding author for the article. Working off-campus? We also investigate the effect of lithium polysulfides dissolved in the electrolyte on the stability and cycling behavior of Li2S–carbon composite cathodes. 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. The in situ synthesis approach allows facile, scalable synthesis of lithium sulfide–carbon composite materials that exhibit improved electrochemical properties.
