摘要： Disclosed herein is a plate-shaped secondary battery constructed in a structure in which an electrode assembly of a cathode/separator/anode structure is mounted in a battery case, and the battery case is sealed by thermal welding, wherein the battery case is provided at a sealing portion around an electrode assembly receiving part thereof with an exhaust guide sealing portion configured in a structure in which a width of the exhaust guide sealing portion decreases from an inside of the sealing portion toward an outside of the sealing portion such that a sealing force of the exhaust guide sealing portion is first released, when high-pressure gas is generated in a battery cell, and therefore, the high-pressure gas is exhausted outside, the exhaust guide sealing portion being thermally welded with a sealing force less than that of a sealing portion located at a remaining region (‘a remaining sealing portion’), and the battery case is further provided at a middle of the exhaust guide sealing portion with a bridge sealing portion extending in parallel to the electrode assembly for interconnecting opposite sides of the remaining sealing portion with a predetermined width, the bridge sealing portion being thermally welded with a sealing force greater than that of the exhaust guide sealing portion.
摘要翻译：这里公开了一种板状二次电池，其结构是将阴极/隔板/阳极结构的电极组件安装在电池壳体中，并且电池壳体通过热焊接而被密封，其中电池壳体设置在围绕电极组件接收其部分的密封部分具有排气引导密封部分，该排气引导密封部分构造成排气引导密封部分的宽度从密封部分的内部朝向密封部分的外部减小，使得密封力首先释放排气导向密封部分，当在电池单元中产生高压气体时，排气导管密封部分的外部压缩空气被排出，排气引导密封部分的热密封力小于位于剩余区域（“剩余密封部”）的密封部，并且电池壳体还设置在排气引导件s的中间其具有平行于电极组件延伸的桥接密封部分，用于将剩余密封部分的相对侧以预定宽度互连，桥接密封部分的热密封力大于排气引导密封部分的密封力。
