NEGATIVE ELECTRODE FOR LITHIUM BATTERY, AND MANUFACTURING METHOD THEREFOR

摘要

PROBLEM TO BE SOLVED: To provide a lithium battery negative electrode and its producting method by preventing an inorganic solid electrolyte thin membrane from being deteriorated by moisture, and precluding workability in assembling of a battery from being disturbed. SOLUTION: The inorganic solid electrolyte thin membrane 3 is covered with a flexible protection sheet 4, in a negative electrode of a lithium battery with the inorganic solid electrolyte thin membrane 3 formed on lithium- containing metal (a lithium metal thin film 2). A polypropylene- or polyethylene- made protection sheet is preferable for the protection sheet 4. The negative electrode is prevented from being deteriorated by moisture until the lithium secondary battery has been assembled, by covering a negative electrode surface with the flexible protection sheet 4 to allow contact close therebetween.
