ELECTRODE ASSEMBLY AND RECHARGEABLE BATTERY WITH THE SAME

摘要

PURPOSE: An electrode assembly prevents the misalignment of a first and second electrode, prevents the bending of a first and second electrode, and minimizes the contraction of a separator. CONSTITUTION: An electrode assembly (100) includes a first electrode (10) including a first active material in a first current collector; a separator (30) which surrounds one end of the first electrode and is laminated on both sides of the first electrode; and a second electrode (20,201) which has a second active material on a second current collector. The first electrode and the separator are fold in the opposite direction from each other from the both end of the second electrode. The second electrode is inserted between the separators and forms a lamination structure of the first electrode, the separator, and the second electrode.
