    摘要： A battery module is configured so that the first cell string 12 and the second cell string 13 are arranged between the first plate member 21 and the second plate member 22 and the second cell string 13 is arranged closer to the second plate member 22 side than the first cell string 12 is and is arranged closer to the outlet side than the first cell string 12 is. At the inlet side of the housing 20, the inlet 25 is arranged closer to the first plate member 21 than to the second cell string 13, at least a part between the inlet side of the second cell string 13 and the second plate member 22 is covered by the inlet-side guide plate 23, and the cooling air is introduced into the housing 20 through the inlet 25 so as to form a flow of the cooling air along the first plate member 21 and a flow of the cooling air along the inlet-side guide plate 23.

    摘要： A lithium-ion secondary battery is provided where a current collecting disk and a current collector foil are joined to each other securely while damage of the foil is suppressed. The lithium-ion secondary battery is provided with a winding group obtained by winding a positive electrode plate and a negative electrode plate via a separator. An uncoated area of the positive electrode current collector foil and an uncoated area of the negative electrode current collector foil project at an upper portion and a lower portion of the winding group, respectively. The current collecting disk (7) has projecting ridge portions on a face thereof opposite to the winding group and flat face portions facing the winding group at positions corresponding to the projecting ridge portions. The projecting ridge portions are formed radially. The end portion of the positive electrode mixture non-application portion and the end portion of the negative electrode mixture non-application portion are caused to abut on the flat face portions of the current collecting disks (7) and joining is performed by irradiating the projecting ridge portions with laser beam.
