Abstract
(EN)
An electrode assembly according to one embodiment of the present invention is a jelly-roll type electrode assembly in which an anode sheet, a cathode sheet, and a separator interposed between the anode sheet and the cathode sheet are wound together, and comprises: one or more electrode taps which are attached to the anode sheet or the cathode sheet, and of which at least some are outwardly extended; and a thermal release tape adhered to the electrode taps, wherein the thermal electrode taps, to which release tape is adhered, are located between the center of the wound electrode assembly and the outer circumferential surface thereof, or on the outer circumferential surface thereof, the thermal release tape comprises a thermal diffusion layer, and the thermal diffusion layer comprises graphite and/or a metal foil.
