A lithium secondary battery includes: a battery case, and an internal electrode bodycontained in the battery case and including a positive electrodea negative electrodeand a separatormade of porous polymer. The positive electrode and the negative electrode are wound and laminated through the separator so that the positive electrode and the negative electrode are not brought into direct contact each other. The battery case is composed of pure aluminum or aluminum alloy in which one or more components selected from manganese, magnesium, silicon and copper is added in aluminum. The lithium secondary battery has high weight energy density, is superior in safety, and is used for, particularly, an electric vehicle.
