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+P₂S₅and Li₂S+SiS₂+ Al₂S₃multi-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

Sulfide Solid Electrolytes Li₂S+GeS₂+P₂S₅and 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+ P₂S₅and 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.
