Sulfide Compounds

Sulfide Compounds mainly refer to the metal elements and metalloid compounds, which have stoichiometric composition changing within a certain range to form a compound-based solid solution. Inter-metallic compound is of its excellent properties between the metal and ceramic, and become an important branch of the new structural materials. Sulfides Compound of Arsenic Sulfide As2S3, Bismuth Sulfide Bi2S3, Gallium Sulfide Ga2S3, Germanium Sulfide GeS2, Indium Sulfide In2S3, Lithium Sulfide Li2S,  Molybdenum Sulfide MoS2, Selenium Sulfide SeS2, Sliver Sulfide Ag2S, Solid Electrolytes Li2S+GeS2+P2Sand Li2S+SiS2+ Al2Smulti-element sulfide composite electrode material, Tin Selenide SnS2, Titanium Sulfide TiS2, Zinc Sulfide ZnS and its (Li, Na, K, Be, Mg, Ca) compounds and Rare Earth compounds can also be synthesized in form of powder, granule, lump, bar, crystal and substrate

Sulfide Solid Electrolytes Li2S+GeS2+P2S5 and Li2S+SiS2+Al2S3 3N 4N (99.9%, 99.99%) All-solid-state lithium battery with non combustible solid electrolyte can avoid the risk of inflammable and explosive, short life and low energy density, meanwhile solid electrolytes can also effectively inhibit the formation of lithium dendrite to improve service life of the battery. Among which sulfide-based solid electrolytes have become more widespread and attracted significant attention because they possess high conductivities and good mechanical properties for the formation of effective interfaces between solids. The most typical sulfide crystalline solid electrolyte is thio-LISICON, a lithium superionic conductor found in the Li2S-GeS2-P2S5 system, which demonstrates highest lithium-ion conductivity of 2.2 × 10-3s cm-1 at room temperature, together with negligible electronic conductivity, high electrochemical stability, wide operating voltage window. Li2S+GeS2+ P2S5 and Li2S+SiS2+ Al2S3, a novel and promising solid electrolytes prepared by a high-energy ball-milling process or by a conventional melt-quenching method, act as both an ionic conductor and a separating membrane in all-solid-state rechargeable lithium batteries.
