Provided are an electrode assembly and a secondary battery having the same. The electrode assembly includes a positive electrode including a positive electrode active material layer, a negative electrode including a negative electrode active material layer, and a separator for separating the positive and negative electrodes from each other. The negative electrode active material layer includes a metal capable of alloying with lithium or lithium vanadium oxide (LiV3O5), the separator includes a porous layer formed by combining a ceramic material with a binder, and the content of the binder is from about 5 to about 15 wt % with respect to 100 wt % of the porous layer. Therefore, in the electrode assembly and the lithium secondary battery having the same of the present embodiments, the content of the binder of the porous layer formed by combining a ceramic material with the binder is limited in a high-capacity lithium secondary battery, and thus a secondary battery capable of improving an internal short circuit and realizing high capacity can be provided. |
