The present invention relates to a technique capable of enhancing the lifespan of a medium-large scale cell of a secondary battery, by increasing the radiation properties. More specifically, the present invention relates to an electrode assembly having a structure of multiple electrodes, which include a slurry layer coated on a current collector, mutually insulating each other. The provided electrode assembly includes: a first area which includes electrode assemblies arranged on both exterior portions of the entire electrode assembly; and a second area arranged with an electrode assembly which is relatively heavier than the electrode assemblies arranged on the first area. |
