A secondary battery includes an electrode assembly including a positive electrode, a negative electrode and a separator interposed therebetween. A container receives the electrode assembly, and a cap assembly is fixed to the container to seal the container. A collector plate is electrically connected to the electrode assembly. The positive electrode, the negative electrode, or both has an uncoated region uncoated with active material. The uncoated region has a bent portion and the collector plate can be electrically connected to the bent portion of the uncoated region. |
