How to Form Solid Lithium Base Batteries and Solid Lithium Base Batteries

摘要

PROBLEM TO BE SOLVED: To provide a solid-state lithium-based battery and a method for forming a solid-state lithium-based battery. SOLUTION: A solid lithium base battery having a high charging and recharging rate (more than 3C) by including a high nitrogen lithium nitride cathode material surface layer between a lithium nitride cathode material layer and a lithium base solid electrolyte layer. Is provided. The high nitrogen lithium cathode material surface layer can be formed by introducing nitrogen into the lithium nitride cathode material. Nitrogen can be introduced during the final stages of the deposition process or by utilizing a process different from the deposition process, such as thermal nitriding. [Selection diagram] FIG. 14
