Disclosed are a lithium metal secondary battery and a battery module including the same, the lithium metal secondary battery comprising: an electrode assembly including an anode, a cathode, and a separator interposed between the anode and the cathode; a non-aqueous electrolyte for impregnating the electrode assembly therein; and a battery case in which the electrode assembly and the non-aqueous electrolyte are embedded, wherein the anode includes an anode current collector and a lithium metal layer, which is formed on at least one surface of the anode current collector, and the charging/discharging conditions of the lithium metal secondary battery allow for charging in a pressurized state and allow for discharging in a non-pressurized state or a pressurized state, and the pressure applied during discharging is controlled to be less than the pressure applied during charging when discharging is performed in the pressurized state. |
