ELECTRODE ASSEMBLY AND BATTERY CELL INCLUDING THE SAME

摘要

An electrode assembly includes a unit cell A in which a first electrode 110, a second electrode 120, and a separator 130 disposed between the first and second electrodes 110 and 120 are stacked on each other or a structure in which the unit cells A are repeatedly stacked with the separator therebetween. A first electrode tab 111 protrudes from the first electrode 110, and a second electrode tab 121 protrudes from the second electrode 120, and the electrodes tabs 111 and 121 have widths that gradually decrease in directions in which the electrodes tabs 111 and 121 protrude outward from the electrodes 110 and 120, respectively.
