摘要： The present invention provides a lithium-ion secondary battery which can suppress internal resistance to a small value. The lithium-ion secondary battery includes a winding group obtained by winding a positive electrode plate and a negative electrode plate via a separator. An end portion of a positive electrode mixture non-application portion 1 projects at an upper portion of the winding group, while an end portion of a negative electrode mixture non-application portion projects at a lower portion of the winding group. Current collecting disks 7 are disposed on both end faces of the winding group so as to face them, respectively, and materials for the current colleting disks are the same materials as those for a positive electrode current collector and a negative electrode current collector. An end portion of the positive electrode mixture non-application portion 1 is joined to a face of the current collecting disk 7 positioned on the side of the winding group at a plurality of joint portions on the positive electrode side, while an end portion of the negative electrode mixture non-application portion is joined to a face of the current collecting disk 7 positioned on the side of the winding group at a plurality of joint portions on the negative electrode side. Some of the joint portions form joint portions taking on a width expansion shape gradually expanding from a joint end portion with the positive electrode mixture non-application portion 1 toward the current collecting disk 7. A volume of the joint portion 25 is increased.

摘要： In a secondary battery, for providing a structure which can enable a welding operation even when a gap is formed between a current collecting plate and a winding assembly, recessed portions are formed in a positive current collecting plate. The recessed portions are disposed opposite to the winding assembly. A laser beam is irradiated to welding protrusions located between the recessed portions to melt the welding protrusions. Here, since the end surface of a positive electrode foil is uneven in height, the positive electrode foil does not contact the positive current collecting plate necessarily. The welding operation is performed by heating, melting, and dropping the welding protrusions by the use of a YAG laser under the welding condition of a laser power of 900 W and a welding speed 2 m/min.
摘要翻译：在二次电池中，为了提供即使在集电板和绕组组件之间形成间隙也能进行焊接操作的结构，在正极集电板中形成有凹部。凹部设置成与卷绕组件相对。将激光束照射到位于凹部之间的焊接突起，以熔化焊接突起。这里，由于正极箔的端面高度不均匀，所以正极箔不必接触正极集电板。在900W的激光功率和2m / min的焊接速度的焊接条件下，通过使用YAG激光器对焊接突起进行加热，熔化，滴下，进行焊接作业。
