Lithium electrode for lithium metal battery and method of manufacturing the lithium electrode

摘要

Disclosed are a lithium electrode for a lithium metal battery, which uses a solid high-ionic conductor having a three-dimensional (3D) porous structure, wherein a lithium metal or lithium alloy is filled into each pore and dispersed, and a method for manufacturing the lithium electrode. By applying a solid high-ionic conductor having a 3D porous structure, an ion conduction path is secured in the lithium electrode using the solid high-ionic conductor instead of a conventional liquid electrolyte, electrical-chemical reactivity in charging and discharging are further improved, and shelf life and high rate capability are enhanced.

1. A method of manufacturing a lithium electrode for a lithium metal battery, the method comprising:
providing a template with a solid high-ionic conductor; removing the template to form the solid high-ionic conductor as a 3D porous structure; filling a lithium metal or lithium alloy in a plurality of open pores of the 3D porous structure; and coupling a collector onto a surface of the solid high-ionic conductor, wherein the 3D porous structure is designed as an irregular and non-ordered porous structure, wherein a reaction activating material is coated onto an interface between the solid high-ionic conductor and the lithium metal or lithium alloy to improve interfacial reaction, and the reaction activating material is coated on the interface by physical vapor deposition (PVD).
