Abstract
A rechargeable battery comprises an electrode group including a positive electrode, a negative electrode with a separator interposed therebetween, a case in which the electrode group is inserted, a cap assembly that is coupled with the case to seal the case, and collector plates that are coupled with the electrode group to transfer an electric current to external terminals. In addition, the collector plates comprise protruding portions that protrude outward from a surface of each of the collector plates.
