    摘要： The present invention relates to a pouch in which a receiving portion having an internal space, and a cover portion for closing the open part of the receiving portion are integrally formed, and a pouch type secondary battery, wherein a bent extension portion is formed around the boundary of the receiving portion and the cover portion. According to the present invention, after the cover portion is bent, the contact surface thereof with the receiving portion is sealed so as to make the inside airtight when assembling the pouch, in which the receiving portion and the cover portion are integrally formed, wherein the bent extension portion is further provided around the boundary of the receiving portion and the cover portion and is sealed, thereby minimizing the penetration of external moisture through the boundary after the pouch is sealed.

    摘要： Provided are an electrolyte which may prevent the degradation of the battery performance by including a functional group which can react with a side reaction site which is responsible for decomposition of negative electrode material components and a functional group which can react with moisture which is responsible for decomposition of positive electrode material components in an electrolyte of the battery to ensure the stability of the battery at high temperatures, and a secondary battery manufactured by adding the same. The present invention may employ a compound including a functional group which can react with a side reaction site of a negative electrode material and a functional group which can react with moisture to maximize the improvement of the storage performance of a secondary battery at high temperatures.
