Title:
METHOD FOR PRODUCING NONAQUEOUS SECONDARY BATTERY
Document Type and Number:
WIPO Patent Application WO/2008/029890
Kind Code:
A1
Abstract:
Disclosed is a method for producing a nonaqueous secondary battery which enables to
produce a nonaqueous secondary battery while suppressing formation of an oxide
coating on the surface of a negative electrode layer. Specifically disclosed is
method for producing a nonaqueous secondary battery, which is characterized by
comprising a negative electrode layer-forming step wherein a negative electrode layer
composed of a metal thin film is formed on a negative electrode collector, an oxide
coating removal step wherein an oxide coating on the surface of the negative electrode
layer is removed, a drying step wherein the negative electrode layer from which
the oxide coating is removed is dried in an inert gas atmosphere, a cooling step
wherein the dried negative electrode layer is cooled in an inert gas atmosphere, a
conveying step wherein the cooled negative electrode layer is conveyed to an assembly
work area, and an assembling step wherein a nonaqueous secondary battery is assembled
in an inert gas atmosphere by using the negative electrode layer conveyed to the
assembly work area.
