    • PURPOSE: A secondary battery is provided to improve the stability of battery by preventing the contact of an electrode tap and a joint part of electrode lead with a battery case by an insulating layer formed on inside of the battery case. CONSTITUTION: A secondary battery comprises a battery case(120) of a laminate sheet comprising a metal layer and a resin layer, in which an electrode assembly(130) of a positive electrode/a separator/a negative electrode. Electrode tabs of the electrode assembly is combined to the end of the opposite side of electrode leads(170,180) which projected to outside of the battery case to form electrode terminals. An insulating layer(200) is formed on the inside of the battery case at the position corresponding with an electrode tab-lead joint part(190).
    • 目的:提供一种二次电池,通过在电池壳体内部形成的绝缘层,防止电极接头与电极引线与电池壳体的接合部分的接触来提高电池的稳定性。 构成:二次电池包括包含金属层和树脂层的层压片的电池壳体(120),其中正极/隔板/负极的电极组件(130)。 电极组件的电极接头组合到电极引线(170,180)的相对侧的端部,该电极引线(170,180)突出到电池壳体的外部以形成电极端子。 在与电极片 - 引线接合部(190)对应的位置处,在电池壳体的内侧形成有绝缘层(200)。
