Abstract

Solid-state lithium-ion batteries with a solid-state antiperovskite electrolyte are disclosed. In one aspect, a solid-state Li3ClO electrolyte is deposited on a Cu-supported thin carbon working electrode using a delamination approach for half-cells with lithium metal as a reference electrode.

First claim

What is claimed is:

1 . A method for preparing solid-state electrolyte based on Lithium Halides for solid-state lithium-ion electrochemical cells.

2 . The method of claim 1 further comprising:
charging and discharging the solid-state electrolyte at elevated temperatures.

3 . The method of claim 1 , wherein the electrolyte comprises a solid-state antiperovskite electrolyte, such as Li 3 ClO.

4 . The method of claim 1 further comprising:
processing the solid-state electrolyte from a solid-state Li 3 ClO superionic glass-ceramic electrolyte.

5 . The method of claim 4 further comprising:
processing the solid-state Li 3 ClO electrolyte by depositing on a Cu-supported thin carbon working electrode using a delamination approach.

6 . The method of claim 1 , wherein the electrochemical cells comprise a CR2025 half-cell.

7 . The method of claim 1 further comprising:
processing the solid-state electrolyte using a C/Cu working electrode and lithium metal as a reference electrode.

8 . The method of claim 2 , wherein the solid-state electrolyte is charged and discharged at a temperature range of 50° C. to 100° C.

9 . A solid-state electrolyte based on Lithium Halides for solid-state lithium-ion electrochemical cells is disclosed and claimed.

10 . The solid-state electrolyte of claim 9 comprising a solid-state Li 3 ClO superionic glass-ceramic electrolyte.

11 . The solid-state electrolyte of claim 9 wherein the electrochemical cell comprises a CR2025 half-cell.

12 . The solid-state electrolyte of claim 9 having an operating charging and discharging temperature range from at least 50° C. to 100° C.
