Abstract: Disclosed is a lithium metal secondary battery which includes: an electrode assembly including a negative electrode, a positive electrode and a separator interposed between the negative electrode and the positive electrode; a non-aqueous electrolyte with which the electrode assembly is impregnated; and a battery casing in which the electrode assembly and the non-aqueous electrolyte are received, wherein the negative electrode includes a negative electrode current collector and a lithium metal layer formed on at least one surface of the negative electrode current collector, the charge/discharge condition of the lithium metal secondary battery includes charging the lithium metal secondary battery under a pressurized state and discharging the lithium metal secondary battery under a non-pressurized or pressurized state, and when the lithium secondary battery is discharged under a pressurized state, the pressure applied during discharge is controlled to be smaller than the pressure applied during charge. A battery module including the lithium metal secondary battery is also disclosed.
