    Abstract: A battery case including a container configured to house an electrode assembly. The container includes a bottom wall and a plurality of side walls, the bottom wall and the side walls are integrated to have an open side opposite to the bottom wall, and which provides a space for housing the electrode assembly. The container includes a composite of a base polymer, a carbon-based filler, and an oligomer or a polymer that is dissolved in a solvent having a solubility parameter of about 15 MPa1/2 to about 30 MPa1/2, and the oligomer or polymer has an amino group or a hydrophobic functional group. The battery case has a water vapor transmission rate (WVTR) of less than about 0.07 g/m2/day measured at a thickness of 1 mm, at 38° C., and relative humidity of 100% according to ISO 15106 or ASTM F1249, and a battery including the battery case.
