A secondary battery includes an electrode assembly including a positive electrode and a negative electrode, and a separator interposed therebetween. Each of the positive and negative electrodes have uncoated regions without active material along an edge. A container is also included for receiving the electrode assembly. A cap assembly is fixed to the container to seal the container. A lead element covers an entire surface of an uncoated region to contact and combine with the uncoated region. A tab extends from the lead element to be disposed within the range of the lead element.
