“…7 5 S 4 and Li 3.4 Si 0.4 P 0.6 S 4 have already been tested as ceramic solid electrolytes in a battery. 6,38,39 Although these compounds exhibit a high electrochemical stability, the cycling in a battery resulted in the formation of an SEI. 36 In this case, the formation of a stable SEI turned out to be favorable, as it promoted electrode/electrolyte contact and led to fast charge transfer across the interface.…”

A new lithium chalcogenidotetrelate, denoted as LiChT phase, with the elemental combination Li/Sn/S was synthesized as solvent-free and solvent-containing salts. We present and discuss syntheses, crystal structures, spectroscopic and thermal properties of the phases, as well as the Li + ion conductivity of Li 4 SnS 4 , which is formally related to the thio-LISICON parent system Li 4 GeS 4 , and thus represents the first member of a new thiostannate-LISICON family. The solvent-free title compound shows a very promising Li + ion conductivity of 7 × 10 −5 S·cm −1 at 20°C and 3 × 10S·cm −1 at 100°C, which is exceptionally high for a ternary compound. Activation energies for the lithium ion transport measured via impedance spectroscopy (0.41 eV) correlate reasonably well with the values (0.29 to 0.33 eV) deduced from ionic mobility studies by 7 Li solid-state NMR spectroscopy. NMR two-time correlation functions suggest the occurrence of an additional, geometrically more restricted, ultraslow-motional process down to 121 K.

“…[2][3][4][5] However, sulfur-based active materials (e.g., S and Li 2 S) show poor electronic and ionic conductivity, 6,7 resulting in a low utilization ratio of active material and poor battery performance.

Composite sulfur electrodes are prepared by prolonged mechanical milling (;300 min) for use in all-solid-state lithium-sulfur batteries, and their structure and electrochemical properties are investigated. These batteries exhibit a high initial discharge capacity (>1500 mAh g −1). Sulfur, acetylene black, and the solid electrolyte Li 3.25 -Ge 0.25 P 0.75 S 4 are mixed by planetary ball milling to form composites that contain amorphous phases of the starting materials, as well as a byproduct with a novel structural unit arising from the reaction between sulfur and the solid electrolyte. Batteries with a composite electrode/Li 3.25 Ge 0.25 P 0.75 S 4 /Li-In anode configuration exhibit a high initial discharge capacity (>1100 mAh g −1). However, the capacity fades during cycling (~500 mAh g −1 at the 30th cycle), possibly because of the increased resistance of the composite. Structural and compositional changes of the byproduct and the solid electrolyte itself during the battery reaction could contribute to the increase in resistance that cause the deterioration of cyclability.

“…Furthermore, sulfur, which is ubiquitous in nature, is environmentally benign and low-cost. [4,[8][9][10][11][12][13][14][15] Li/S cells have become one of the most promising rechargeable cell systems, showing great potential in meeting the rigorous needs for electrical vehicles and grid-scale stationary storage. Despite their advantages, Li/S cells still are affected by some intrinsic drawbacks.…”

Li2S nano spheres anchored to single-layered graphene as a high-performance cathode material for lithium/sulfur cells

et al. 2016

TitleLi2S nano spheres anchored to single-layered graphene as a high-performance cathode material for lithium/sulfur cells b s t r a c tFully lithiated lithium sulfide (Li 2 S) has become a promising cathode material for Li/S cells due to its high theoretic capacity (1166 mA h g À 1 ) and specific energy (2600 W h kg À 1 ). However, low utilization of sulfur and poor rate capability still hinder the practical application of Li/S cells. In this paper, a carbon coated Li 2 S/graphene composite (Li 2 S/G@C) was developed by incorporating Li 2 S nano spheres with single-layered graphene and further forming a durable protective carbon layer on the surface of the Li 2 S particles using a facile CVD method. The high rate capability and remarkable cycle life of the Li 2 S/G@C cathode were demonstrated, which was mainly attributed to the unique structure of the Li 2 S/G@C that can significantly improve not only the electrical conductivity, but also the mechanical stability of the sulfur cathode.
