Beschreibung
Zusammenfassung:	The present invention relates to solid materials which are obtainable by melt-quenching mixtures of lithium sulphide, boron sulphide, boron oxide and lithium halides, thereby forming a glassy solid which is suitable for use as a lithium-ion conducting electrolyte. These sulphide based lithium-ion conducting solid electrolytes exhibit a high ionic conductivity. La présente invention concerne des matériaux solides qui peuvent être obtenus par extinction à l'état fondu de mélanges de sulfure de lithium, de sulfure de bore, d'oxyde de bore et d'halogénures de lithium, formant ainsi un solide vitreux qui est approprié pour une utilisation en tant qu'électrolyte conducteur d'ions lithium. Ces électrolytes solides conducteurs d'ions lithium à base de sulfure présentent une conductivité ionique élevée.
