In an example embodiment, the secondary battery includes an electrode assembly (100a) including a plurality of unit electrode plates (100) each including a pair of non-coating portion tabs (140) at a side and a plurality of separators each located between the unit electrode plates (140); and the pair of non-coating portion tabs (140) are bent in opposite directions and welded to a current collector plate (300). The pair of non-coating portion tabs are bent in opposite directions to be welded to the current collector plate, and welding may be complementarily performed, thereby securing electrical stability.",
