Abstract: Disclosed are a lithium-ion supply electrode for real-time microscopic analysis and a method of manufacturing same. The lithium-ion supply electrode includes a solid electrolyte layer including a solid electrolyte, a lithium layer formed on the solid electrolyte layer and including lithium, and a protective layer formed on the lithium layer and including a metal. Therefore, lithium in the electrode does not undergo oxidation in a short time. Therefore, the lithium-ion supply electrode can be used for real-time analysis of structural changes and interfacial reactions of lithium secondary battery materials using a transmission electron microscope.
