Abstract
A method for preparing a lithium ion conductive sulfide, which is capable of independently controlling the elemental ratio of lithium (Li), phosphorus (P), sulfur (S), etc, is provided. The method for preparing a lithium ion conductive sulfide can provide a lithium ion conductive sulfide having a crystal structure and an anion cluster distribution distinguished from those of existing ones.
Claims8
A method for preparing a lithium ion conductive sulfide comprising lithium (Li), phosphorus (P) and sulfur (S), which comprises:
- (1) preparing a mixture comprising lithium sulfide (Li2S) and phosphorus pentasulfide (P2S5);
- (2) vitrifying the mixture by pulverizing the mixture;
- and
- (3) crystallizing the vitrified mixture by heat-treating the vitrified mixture,
- wherein the composition ratio of lithium, phosphorus and sulfur in the lithium ion conductive sulfide is controlled independently by performing the vitrification and the crystallization after mixing one or more of elemental phosphorus and elemental sulfur to the mixture in (1).
