Summary:A purpose of the present invention is to provide a battery case having excellent moisture transmission resistance. More specifically, the present invention relates to the battery case, a battery including an electrode assembly contained in a container of the battery case, and a method for manufacturing the battery, wherein the battery case includes the container containing the electrode assembly. The container includes a bottom wall and a plurality of side walls and the bottom wall and the side walls are integrated to have an open side opposing the bottom wall and form a space where the electrode assembly is to be contained. The container is a formed product of composition including a base polymer and an inorganic moisture absorbent distributed on the base polymer, wherein a water vapor transmission rate (WVTR) measured under 38°C and 100% of a relative humidity according to ISO 15106 and ASTM F1249 is less than 0.05 g/m^2/day. 전극 조립체를 수용하는 수용부(container)를 포함하는 전지 케이스로서, 상기 수용부는 하부벽(bottom wall) 및 복수개의 측벽(side wall)들을 포함하고, 상기 하부벽 및 상기 측벽들은 일체화되어 상기 하부벽에 대향하는 개방면(open side)을 가지며 전극 조립체가 수용될 공간을 형성하고, 상기 수용부는 베이스 폴리머, 및 베이스 폴리머에 분산된 무기 흡습제를 포함하는 조성물의 성형품으로서, ISO 15106 및 ASTM F1249에 따라 38℃ 및 상대습도 100%에서 측정한 수증기투과율(WVTR)이 0.05 g/m/day 미만인 전지 케이스, 이 전지 케이스의 상기 수용부에 수용되는 전극 조립체를 포함하는 전지, 및 상기 전지의 제조 방법에 관한 것이다.
