  • Jelly-roll of structure having elastic member adhered on active material-non-coated portion and secondary battery employed with the same
    Patent number: 8993143
    Abstract: Disclosed herein are a winding type electrode assembly (‘jelly-roll’) constructed in a structure in which a cathode sheet and an anode sheet are wound in a circle while a separator is interposed between the cathode sheet and the anode sheet or the assembly is compressed in one direction after winding, wherein the jelly-roll includes an active material non-coated portion formed at the wound end of the jelly-roll, a conductive tape attached to the wound end of the jelly-roll for covering the wound outside of the jelly-roll including the active material non-coated portion, and an elastic member attached to the inside of the active material non-coated portion, the elastic member having a thickness equivalent to 50 to 200% of the height of an active material layer, and a secondary battery including the same.
