    • Provided is a lithium secondary battery which uses a lithium manganese metal oxide as a cathode active material and a non-graphitic carbon material as an anode active material, and based on the total weight of the electrolyte, contains 0.1 to 20% by weight of a salt represented by Formula I in a lithium salt-containing non-aqueous electrolyte: R4X+YZn−  (I) wherein R, X, Y, Z and n are as defined in the specification. The lithium secondary battery of the present invention can improve low-temperature properties of the battery by increasing the lithium ion-electrode reactivity and decreasing the electrode-interface resistance, via the formation of a charge double layer at the cathode-anode interface upon charging/discharging of the battery at a low temperature, and therefore can be preferably used in medium/large battery systems such as power sources for electric vehicles (EVs) and hybrid electric vehicles (HEVs) requiring operation under severe conditions.
    • 提供了使用锂锰金属氧化物作为正极活性物质和非石墨碳材料作为负极活性物质的锂二次电池,并且基于电解质的总重量,含有0.1〜20重量%的 在含锂盐的非水电解质中由式I表示的盐:<?in-line-formula description =“In-line formula”end =“lead”→> R (I)<?in-line-formula description =“In-line Formulas”end =“tail”?>其中R X,Y,Z和n如说明书中所定义。 本发明的锂二次电池可以通过在充电/充电时在阴极 - 阳极界面处形成电荷双层来提高锂离子电极反应性和降低电极界面电阻,从而提高电池的低温性能, 因此可以优选用于需要在恶劣条件下操作的电动车辆(EV)和混合电动车辆(HEV)的动力源等中型/大型电池系统中。

    • Provided are a pouch and a pouch type secondary battery, which includes an accommodating part having an inner space, and a cover part integrally formed with the accommodating part and covering an opening of the accommodating part. A bending extension is disposed around an interface between the accommodating part and the cover part. When the pouch into which the accommodating part and the cover part are integrated is assembled, the cover part is bent, and then, a contact surface between the accommodating part and the cover part is sealed, thereby sealing the inside of the pouch. At this point, the bending extension disposed on the interface disposed between the accommodating part and the cover part is also sealed to thereby prevent external moisture from being introduced through the interface after the sealing of the pouch.
    • 提供一种袋和袋式二次电池,其包括具有内部空间的容纳部分和与容纳部分一体形成并覆盖容纳部分的开口的盖部分。 弯曲延伸部设置在容纳部和盖部之间的界面周围。 当容纳部分和盖部分被整合到其中的袋被组装时,盖部分被弯曲,然后密封容纳部分和盖部分之间的接触表面,从而密封袋的内部。 此时,设置在容纳部和盖部之间的界面上的弯曲延伸部也被密封,从而防止在密封袋之后通过界面引入外部水分。
