Abstract:
A secondary battery. An electrode assembly is mounted in a container. The electrode assembly is formed by winding a positive electrode and a negative electrode with respect to a separator interposed between the positive and negative electrodes. A cap assembly is fixed to the container to seal the container assembly to provide a terminal for electrical current. An uncoated region is formed along the edge of the length direction of the positive electrode or the negative electrode. The uncoated region is left uncoated with an active material. A collector plate includes a contact portion of the curved shape to be electrically connected to the uncoated region.
