ELECTRODE ASSEMBLY AND SECONDARY BATTERY HAVING THE SAME

摘要

An electrode assembly and a secondary battery including the same, the electrode assembly including a first electrode plate, the first electrode plate including a first electrode collector on which a first active material is coated, and a first electrode tab protruding in parallel with a lengthwise direction of the first electrode collector; a second electrode plate, the second electrode plate including a second electrode collector on which a second active material is coated, and a second electrode tab protruding in parallel with a lengthwise direction of the second electrode collector; a first separator between the first and second electrode plates; and a second separator at an outside of the second electrode plate, wherein the first and second electrode tabs protrude in directions opposite to each other perpendicular to a winding axis.
