Abstract: Battery housing structures and battery apparatuses including the same are provided. A battery housing structure may include a case including an accommodation region in which a battery unit is accommodated, and an elastic member assembly provided in the case and configured to apply a pressure to the battery unit accommodated in the accommodation region. The elastic member assembly may include at least one first elastic member having an elastic coefficient that increases when a displacement increases and at least one second elastic member having an elastic coefficient that decreases when a displacement increases. The at least one first elastic member and the at least one second elastic member may have different structures or may be arranged in different directions.
