<P>PROBLEM TO BE SOLVED: To ensure that the alignment of cathode and anode plates in a secondary battery will be maintained even when mechanical shock or vibration is applied to the electrode assembly from the outside, and to provide a manufacturing method of the secondary battery. <P>SOLUTION: A secondary battery, disclosed as an example, includes an electrode assembly and an enclosure for accommodating the electrode assembly. The electrode assembly includes a first electrode current collector and a first electrode plate having a first electrode tab protruding from a negative side of the first electrode current collector, a second electrode current collector and a second electrode plate having a second electrode tab protruding from a negative side of the second electrode current collector, a first separator which is positioned between the first and second electrode plates and which includes a central part and an edge part on the periphery around the central part, and a second separator which is positioned at a negative side of the first or the second electrode plate on an opposite side of a plane facing the first separator and which includes a central part and an edge part on the periphery around the central part. The edge part of the first separator and that of the second separator are connected together in at least a junction. <P>COPYRIGHT: (C)2012,JPO&INPIT |
