    摘要: A cathode and a battery including a cathode active material including a layer-structured material having a composition of xLi 2 MO 3 -(1-x)LiMeO 2 ; and a metal oxide having a perovskite structure. The cathode active material may have improved structural stability by intermixing a metal oxide having a similar crystalline structure with the layer-structured material, and thus, life and capacity characteristics of a cathode and a lithium battery including the metal oxide may be improved.

    摘要: An electrolyte for a lithium secondary battery, the electrolyte including a lithium salt, a non-aqueous organic solvent, and a polar additive based on a substituted heterobicyclic compound. Oxidation of the electrolyte is prevented by formation of a polar thin film on a surface portion of the positive electrode, which facilitates transfer of lithium ions. The lithium secondary batteries using the electrolyte have excellent high temperature life characteristics and high temperature conservation characteristics.
