Abstract
A rechargeable battery according to embodiments of the present invention has improved safety against puncture and collapse. The secondary battery includes an electrode assembly, a case, a first electrode terminal and a second electrode terminal, a cap plate, and a short circuit member. The electrode assembly includes a first electrode, a separator, and a second electrode. The case contains the electrode assembly. The first electrode terminal and a second electrode terminal are electrically connected to the first electrode and the second electrode of the electrode assembly, respectively. The short circuit member extends from the end of one of the first electrode and the second electrode and is wound around the outermost periphery of the electrode assembly to short circuit the electrode assembly when the secondary battery is punctured or collapsed.
