Abstract

The present disclosure relates to a manufacturing process of the solid-state glass-ceramic electrolytes, known in the art as antiperovskites. Specifically, the disclosure is focused on manufacturing of the solid-state electrolyte from the corresponding precursors directly on the active electrode surface of an electrochemical device, specifically anode or cathode of the lithium-ion or lithium metal batteries.

First claim

What is claimed is:

1 . A solid-state glass-ceramic electrolyte electrochemical device, comprising:

2 . The solid-state glass-ceramic electrolyte of claim 1 , wherein the solid-state electrolyte layer is melted onto the upper surface of the metal foil layer.

3 . The solid-state glass-ceramic electrolyte of claim 1 , wherein the metal foil layer is comprised of nickel.

4 . The solid-state glass-ceramic electrolyte of claim 1 , wherein the metal foil layer does not adhere to the solid-state electrolyte layer.

5 . The solid-state glass-ceramic electrolyte of claim 1 , wherein the solid-state electrolyte layer comprises a solid-state glass-ceramic electrolyte.

6 . The solid-state glass-ceramic electrolyte of claim 5 , wherein solid-state glass-ceramic electrolyte comprises lithium undoped or doped antiperovskites and their polymorphs.

7 . The solid-state glass-ceramic electrolyte of claim 5 , further comprising:
at least one inorganic precursor of the solid-state glass-ceramic electrolyte melted on the metal foil layer.

8 . An electrochemical device, comprising:
at least one solid-state glass-ceramic electrolyte; a battery with a metal and at least one electrode.

9 . The electrochemical device of claim 8 , further comprising:
a metal foil surface having melted thereon the solid-state glass-ceramic electrolyte.

10 . The electrochemical device of claim 8 , further comprising:
at least one inorganic precursor of the solid-state glass-ceramic electrolyte melted on a metal foil.

11 . The electrochemical device of claim 8 , wherein the solid-state glass ceramic electrolyte comprises lithium undoped or doped antiperovskites and their polymorphs.

12 . The electrochemical device of claim 10 , wherein the at least one inorganic precursor of the solid-state glass-ceramic electrolyte melted on the metal foil is in direct contact with the electrode of the electrochemical device.

13 . The electrochemical device of claim 8 , wherein the electrode comprises aluminum-supported cathode or anode including copper-supported various graphite-, silicon-, or metal oxide-based nanocomposites.

14 . The electrochemical device of claim 8 , further comprising:
aluminum-supported cathode or copper-supported anode in direct contact with at least one inorganic precursor forming a fully integrated electrode-electrolyte multilayer architecture.

15 . An electrochemical device, comprising:
at least one solid-state glass-ceramic electrolyte; and at least one electrode.
