Abstract

A Li—Sn—O—S compound, a manufacturing method therefor and use thereof as an electrolyte material of Li-ion batteries, and a Li—Sn—O—S hybrid electrolyte are provided. The Li—Sn—O—S compound of the present invention is laminated Sn—O—S embedded with lithium ions. The Li—Sn—O—S compound is represented by the formula Li3x[LixSn1−x(O,S)2], where x>0. The manufacturing method for a Li—Sn—O—S compound includes the following steps of: (S1000) providing a Sn—O—S compound; (S2000) adding a lithium source into the Sn—O—S compound to form a Li—Sn—O—S precursor; and (S3000) performing calcination on the Li—Sn—O—S precursor in a vulcanization condition.

First claim

What is claimed is:

1. A Li—Sn—O—S compound, wherein the Li—Sn—O—S compound is laminated Sn—O—S embedded with lithium ions;
wherein the Li—Sn—O—S compound is represented by the following formula (I):
Li 3x [Li x Sn 1-x (O,S) 2 ],  Formula (I)

wherein x>0.

2. The Li—Sn—O—S compound according to claim 1 , wherein the Li—Sn—O—S compound is represented by Li[Li 1/3 Sn 2/3 (O,S) 2 ].

3. The Li—Sn—O—S compound according to claim 1 , wherein the Li—Sn—O—S compound is represented by Li 2 Sn(O,S) 3 .

4. A Li—Sn—O—S hybrid electrolyte, comprising:
the Li—Sn—O—S compound according to claim 1 ; and
a gel polymer electrolyte.
