Nonaqueous secondary battery having multiple-layered negative electrode

A method for producing a nonaqueous secondary battery which comprises:

• a positive electrode sheet having a layer mainly comprising a lithium-containing metal oxide;
• a negative electrode sheet having (1) a layer mainly comprising at least one compound selected from the group consisting of a metal oxide, a metalloid oxide, a metal chalcogenide and a metalloid chalcogenide which are capable of intercalating and deintercalating lithium, (2) at least one auxiliary layer containing water-insoluble electrically conductive particles provided on said layer (1), and (3) a metal material film mainly comprising lithium laminated on said auxiliary layer (2);
• an electrlytic solution containing a lithium salt;
• and
• a separator;
• said method comprising:
• laminating (1) a layer mainly comprising at least one compound selected from the group consisting of a metal oxide, a metalloid oxide, a metal chalcogenide and a metalloid chalcogenide which are capable of intercalating and deintercalating lithium, (2) at least one auxiliary layer containing water-insoluble electrically conductive particles, and (3) a metal material film mainly comprising lithium in said order;
• and
• aging after injection of the electrolytic solution so that lithium is pre-intercalated into the negative electrode sheet,
• wherein said auxiliary layer is laminated with said metal material film mainly comprising lithium either:
• (i) wholly, or
• (ii) partially in at least one pattern selected from the group consisting of stripe, frame, and disc shapes.
