摘要： Disclosed is a battery 10 including: an electrode group including a positive electrode, a negative electrode, and a separator; an electrolyte; and a battery container accommodating the electrode group and the electrolyte. The battery container includes an accommodating portion 16 having an opening, and a lid sealing the opening of the accommodating portion 16. The battery container includes a liquid-retaining portion 16a retaining the electrolyte therein below the liquid surface of the electrolyte, and a gas-retaining portion 16b retaining gas therein above the liquid surface of the electrolyte. The liquid-retaining portion 16a of the side portion of the battery container is thinner than the gas-retaining portion 16b of the battery container. This suppresses scattering of fragments etc. in the event of rupture of a secondary battery due to an increase in the internal pressure. The safety of the secondary battery is thus increased.
摘要翻译：公开了一种电池10，其包括：包括正极，负极和隔膜的电极组; 电解液以及容纳电极组和电解质的电池容器。电池容器包括具有开口的容纳部分16和密封容纳部分16的开口的盖子。电池容器包括将电解液保持在电解液的液体表面之下的液体保持部分16a，保持部分16b将气体保留在电解液的液体表面之上。电池容器的侧部的液体保持部分16a比电池容器的气体保持部分16b薄。由于内部压力的增加，二次电池的破裂的情况下，能够抑制碎片等的散射。因此，二次电池的安全性增加。

摘要： A housing for containing electrode assemblies and an electrolyte includes a cover 18 having a pair of long-side ends 18e. Peripheral thinned portions 11 are formed by cutting the inner face of a top plate 18a near the long-side ends 18e in parallel with the long-side ends 18e. A central thinned portion 15 is formed by cutting the central part of the outer face of the top plate 18a in parallel with the long-side ends 18e. This facilitates the rupture of a housing 1 due to an increase of the inner pressure, while ensuring the strength of the housing 1 to withstand external pressure.
摘要翻译：用于容纳电极组件和电解质的壳体包括具有一对长边端部18e的盖子18。通过在长边侧端部18e的长边侧端部18e平行地切断顶板18a的内表面而形成外周变薄部11。通过切割顶板18a的外表面的中心部而与长边端部18e平行地形成中央的薄壁部15。这有助于由于内部压力的增加而导致壳体1的破裂，同时确保壳体1的强度以承受外部压力。
