    摘要： The invention provides a method capable of more simply and easily mass-producing sealed lithium secondary batteries having a stable battery performance. This method of manufacturing a sealed lithium secondary battery having an electrode assembly, an electrolyte solution and a sealable metallic or nonmetallic hard case of a given shape includes the steps of housing the electrode assembly, which includes a positive electrode and a negative electrode, and the electrolyte solution within the hard case; negatively pressurizing the interior of the hard case and sealing the hard case in the negatively pressurized state; carrying out, after the sealing step, initial charging so as to adjust the battery to a voltage at which the electrode assembly generates gases; and carrying out, after the initial charging step, main charging so as to charge the battery to a predetermined voltage. During the interval following the sealing step and up until the main charging step, the hard case is maintained in a sealed state so that the interior of the hard case is not open to the atmosphere.

    摘要： It is a task of the invention to provide a battery that allows a gas produced inside a flat wound electrode body to be easily discharged to the outside of the electrode body, and restrains an electrolytic solution (a retained electrolytic solution) extruded from the flat wound electrode body through charge/discharge from directly flowing out to the outside of the flat wound electrode body, and a method of manufacturing this battery. The battery is equipped with a flat wound electrode body, a collector member, and a retained electrolytic solution. The flat wound electrode body has an active material layer wound portion that is obtained by winding an electrode plate, has a flat oval cross-section, and has a wound active material layer forming portion, and an exposed wound portion that has a wound foil exposed portion. An exposed wound central portion is detached from at least one of two exposed wound end portions while maintaining contact with an active material layer wound portion that is adjacent to the exposed wound central portion in an axial direction. The collector member is joined to the exposed wound central portion.
