ELECTRODE ASSEMBLY AND SECONDARY BATTERY INCLUDING THE SAME |
摘要 |
An electrode assembly includes an electrode jelly-roll, which includes a winding including a first electrode plate, a second electrode plate, and a separator disposed between the first and second electrode plates; an outer surface parallel to a winding axis of the prismatic electrode jelly-roll, side surfaces perpendicular to the winding axis; a first electrode tab, which is electrically connected to the first electrode plate and extends in a winding axis direction of the prismatic electrode jelly-roll; a second electrode tab, which is electrically connected to the second electrode plate and extends in a winding axis direction of the electrode jelly-roll, wherein an end portion of at least one of the first electrode tab and the second electrode tab is bent in a direction opposite to the direction in which the corresponding electrode tab extends and faces an outer surface of the prismatic electrode jelly-roll. |
