Abstract: An electrochemical device includes an electrode assembly in which a length direction, a thickness direction and a width direction are defined, and a packing member including a first packing film and a second packing film for packing the electrode assembly. The electrochemical device includes a bonded portion formed by bonding an edge of the first packing film with an edge of the second packing film. The bonded portion is configured to be bendable around an axis of the width direction, in a region in the length direction.

Abstract: An electrode assembly includes an electrode stack structure including a first electrode assembly sheet having flexibility and a second electrode assembly sheet having flexibility, where and the first and second electrode assemblies are alternately disposed one on another, and a binding unit which binds a portion of the electrode stack structure. The first electrode assembly sheet includes first and second separator films disposed to face each other, a first electrode sheet which is disposed between the first and second separator films and includes a first electrode collector and a first active material layer, and a first confining unit which restricts a movement of the first electrode sheet with respect to the first and second separator films.
