Process for preparing lithium sulfide

摘要

The invention relates to a novel process for preparing lithium sulfide and to the use thereof, wherein a reaction of lithium-containing strong bases with hydrogen sulfide is undertaken in an aprotic organic solvent within the temperature range from −20 to 120° C. under inert conditions. The lithium sulfide obtained by the process is used as a positive material in a galvanic element or for the synthesis of Li ion-conductive solids, especially for the synthesis of glasses, glass ceramics or crystalline products.

主权项

1. A method for preparing lithium sulfide comprising:
reacting a lithium-containing base selected from the group consisting of a lithium alkylene, a lithium arylene, and a lithium amide with hydrogen sulfide in an aprotic organic solvent at a temperature of from −20° to 120° C. under inert conditions, wherein the aprotic organic solvent comprises at least one member selected from the group consisting of an aliphatic hydrocarbon, an aromatic hydrocarbon and an etheric solvent.
