Abstract

Disclosed herein is a battery case configured to receive an electrode assembly and an electrolytic solution therein, the electrode assembly including a positive electrode, a negative electrode, and a separator interposed between the positive electrode and the negative electrode, the battery case including a layer structure and a gas adsorption layer formed on the inner surface of the layer structure, the gas adsorption layer including a gas adsorption material layer configured to adsorb a reaction gas that may be generated within the battery case during abnormal functioning of the electrode assembly, and a blocking layer formed on an exposed surface of the gas adsorption material layer, the blocking layer configured to prevent the gas adsorption material layer from being exposed to an ambient gas during assembly of the battery case.
