Abstract: Embodiments of the present invention are directed to electrode assemblies and secondary batteries using the same. The secondary battery includes an electrode assembly including a positive electrode having a positive active material, a negative electrode including a negative active material, and a separator between the positive and negative electrodes. The positive active material includes a lithium composite oxide represented by LiCO1−x−yMgxTiyO2 where 0.0056≦x≦0.0089, and 0.0029≦y≦0.0045. The electrode assembly and the lithium secondary battery including the same show good discharge efficiency even with increases in C-rate, and substantially prevent reductions in battery capacity resulting from battery deterioration, thereby improving battery lifespan.
