Abstract
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.
