摘要： A cylindrical battery has a crimp region is formed at the upper end of the container. The upper end of the crimp region is gently bent to surround a gasket located at the inside of the crimp region. A bent front end is continuously bent twice to press the gasket, while the bent front end extends inward, such that a radius of curvature (R1) of the first bent area is less than a radius of curvature (R2) of the second bent area. The upper end of the crimp region of the cylindrical container is continuously bent twice in a predetermined condition. Consequently, when external physical impacts are applied to the battery, and when the internal pressure of the battery increases, the sealed portions are restrained from being separated from each other, thereby preventing the leakage of an electrolyte and thus greatly improving the safety of the battery.
摘要翻译：圆筒形电池在容器的上端形成有压接区域。卷曲区域的上端被轻轻地弯曲以包围位于卷曲区域内部的垫圈。弯曲的前端连续弯曲两次以按压垫圈，同时弯曲的前端向内延伸，使得第一弯曲区域的曲率半径（R1）小于第二弯曲区域的曲率半径（R2）。圆筒形容器的压接区域的上端在预定条件下连续弯曲两次。因此，当对电池施加外部物理冲击时，并且当电池的内部压力增加时，密封部分被抑制彼此分离，从而防止电解液的泄漏，从而大大提高电池的安全性。

摘要： Disclosed herein is a cylindrical secondary battery including a cap assembly constructed in a structure in which a vent, which intercepts electric current and discharges pressurized gas when the interior pressure of the battery is increased due to abnormal operation of the battery, is in contact with a top cap having a protruding central part, wherein the end of the vent is bent to surround the outer circumferential surface of the top cap, and a groove for preventing the leakage of an electrolyte and preventing the occurrence of defectiveness of the battery during the assembly of the battery is formed at interfaces between the vent and the top cap such that the groove is arranged in parallel with the outer circumferential surface of the top cap. The secondary battery according to the present invention has the effect of accomplishing high charging and discharging rate, providing uniform output even when external physical impacts, such as vibration or dropping, are applied to the secondary battery, and preventing the occurrence of defectiveness during the assembly of the secondary battery. Furthermore, the leakage of the electrolyte out of the battery is restrained under these conditions. Consequently, the secondary battery according to the present invention can be preferably used as a high-output power source.

摘要： Disclosed herein are an electrode assembly having separators the upper ends of which are sealed and a secondary battery including the same. The electrode assembly has a cathode/separator/anode structure that can be charged and discharged. The separators, which protrude beyond the upper ends of the electrodes, are bent in one direction, the separators are heat-treated such that the bent state of the separators is fixed, and an insulative coating layer is formed at the bent surfaces of the separators. Consequently, foreign matter is prevented from being introduced into the electrode assembly, and therefore, the safety of electrode assembly is improved.
