摘要： A secondary battery includes an electrode assembly having a positive electrode, a negative electrode and a separator interposed between the positive and negative electrodes and a container for receiving the electrode assembly inside thereof. The secondary battery also includes a cap assembly fixed to the container to seal the container and a gasket disposed between the container and the cap assembly. The gasket has at least one concavo-convex portion on a surface contacting the container and/or the cap assembly. This improved gasket structure enhances the air tightness of the secondary battery.
