Provided are an electrode assembly for a lithium secondary battery which is prevented in the deformation of an electrode assembly and can generate the heat of an electrode plate, and a prismatic lithium secondary battery containing the electrode assembly. The electrode assembly(230) comprises a first electrode plate which comprises a first current collector, a first electrode active material part, a first electrode uncoated area and a first electrode tap; a second electrode plate which comprises a second current collector, a second electrode active material part, a second electrode uncoated area and a second electrode tap; and a separator(241), wherein the second electrode tap(247) is located at the center part of the electrode assembly, and the part of the second electrode tap in contact with the second electrode uncoated area has a width expanded compared with the other side. |
