Battery Case And Secondary Battery

Abstract: The present invention relates to a battery case and a secondary battery, and, more specifically, to a battery case and a secondary battery, which comprises the battery case and a gas adsorption unit accommodated inside the case, wherein the gas adsorption unit has a gas adsorption pack that opens if the internal pressure of the case increases. According to the present invention, provided are the battery case and the secondary battery, which quickly absorb, through the opening of the gas adsorption pack accommodated inside the case and filled with a gas adsorbent without an additional system or sensing device, gas generated inside the battery due to abnormal operation or deterioration of battery lifespan, and thus ensures battery stability, prevent deformation of the battery case, lower battery resistance, and, furthermore, allow the secondary battery to be operated even after the gas adsorption pack is opened.
