Abstract
A rechargeable battery having a current collector plates that a have a stable and reliable connection to an uncoated portion of one of the anode and the cathode of the electrode assembly. The rechargeable battery includes the electrode assembly, a case, a cap assembly, and the current collecting plates. The electrode assembly includes the anode, the cathode, and a separator arranged between the anode and the cathode. The case houses the electrode assembly. The cap assembly closes and seals the case and includes an electrode terminal. The current collecting plates connect the electrode assembly and the cap assembly and each include a plurality of current collecting protrusions that extend into the electrode assembly. The current collecting protrusions of one current collector plate are arranged among the current collecting protrusions of another current collecting plate, and the uncoated region of one of the anode and the cathode is arranged among these current collecting protrusions.
