Abstract: The present invention relates to an electrode assembly including a separator and a lithium secondary battery including the same for improving safety. The electrode assembly including a positive electrode, a negative electrode and a separator further includes a gasification material possibly being electrolyzed at a certain voltage to generate a gas. Since the electrode assembly and the lithium secondary battery including the same include the gasification material possibly being electrolyzed at the certain voltage to generate the gas, the safety of the battery may be increased. Since the gasification material is coated on the surface of the separator not on the electrode, the resistance increase of the battery may be restrained and the capacity lowering of the battery may be remarkably decreased. The lifetime of the battery is good.
