<p>PURPOSE: A secondary battery is provided to improve stacking workability of an electrode assembly as the convenience of arranging work is improved, and to improve stability of a battery together with improving power performance. CONSTITUTION: A secondary battery comprises: an electrode assembly comprising a first electrode and a second electrode plates(150), a separator, and an alignment part(155) formed on each first and second electrodes and the separator; a battery case(110) accepting the electrode assembly; and an alignment guide part(115), which is formed to one body with the battery case, aligning the first and the second plate and the separator by being inserted to the alignment par. The alignment part is formed by a pair on opposite edge of the first and the second plates, and the separator.</p> |
