A process for producing a chargeable-and-dischargeable thin film lithium secondary battery, which includes a substrate, a positive electrode film arranged on the substrate and formed in a structure of which lithium is insertable and releasable, an electrolyte film which is arranged on the positive electrode film and being in contact with the positive electrode film and contains lithium ions and in which lithium ions are movable, and a negative electrode film made of metallic lithium and arranged on the electrolyte film and being in contact with the electrolyte film, wherein after the negative electrode film is formed, a lithium carbonate film is formed on a surface of the negative electrode film by bringing a surface of the negative electrode film into contact with a surface-treating gas containing a rare gas and carbon dioxide. The process does not change the properties of a metallic lithium film as a negative electrode. |
