Lithium sulfide (Li 2 S) is a critical material for two systems of next-generation advanced lithium batteries. However, its practical applications are seriously impeded by its expensive price due to its troublesome storage and problematic production. Herein we report the synthesis of Li 2 S by thermally reducing lithium sulfate with hydrogen.
Among all candidates being explored, lithium-sulfur batteries are a very promising system to be commercialized in the near future. Towards this end, the development of lithium sulfide (Li 2 S) nanocrystal-based cathodes has received tremendous effort and witnessed multiple reviews.
Lithium sulfide (Li2S) is the critical raw material used for the synthesis of sulfide solid-state electrolytes, but its high cost and pollution restrict the commercialization of sulfide solid-state electrolytes and sulfide-based all-solid-state batteries. A new green and cost-effective method for the synthes
This review article comprehensively overviews the research advance of lithium sulfide nanocrystals as cathode materials for lithium-sulfur batteries, according to the characteristics of materials synthesis and electrode fabrication. 1. Introduction
Within this battery generation, liquid electrolytes are replaced with solid electrolytes. Compared with other solid electrolyte classes, sulfide-based electrolytes exhibit very high ionic conductivities. Due to the high reactivity of sulfides, exposure to elements within the ambient atmosphere is challenging.
(1) Solid-state batteries (SSBs), as a potential advancement of conventional LIBs, represent a particularly promising technology for future applications. In SSBs, the lithium-ion conductor is no longer a flammable liquid electrolyte but rather a solid electrolyte, which leads to significant advantages regarding their safety and performance.

However, the hydrogen cannot only adsorb on the graphite powder surface but also intercalate inside of the graphite and be accumulated there in abundance. 72–74 The ability of the hydrogen to be accumulated in electrodes is proved also by the studies, 24,25 in which it was shown that the hydrogen was released at lithium-ion batteries storage in their charged state.
