Electrode assembly and battery pack including the same

Abstract

An electrode assembly includes a structure including a first electrode plate and a second electrode plate that are wound together, and a separator between the first electrode plate and the second electrode plate, a first electrode tab that is electrically connected to the first electrode plate, and a second electrode tab that is electrically connected to the second electrode plate. The structure includes a pair of grooves at opposite sides of the structure, the grooves being formed by compression of the structure at the opposite sides in a direction perpendicular to a winding surface. The structure including a first part and a second part that are oppositely located with respect to a reference line connecting the pair of grooves, and the second part is shifted in a first direction such that the second part is partially misaligned with the first part.
