摘要：Provided are a secondary battery and an assembling method thereof, which canensure a battery capacity and improve welding quality of a current collector. Thesecondary battery includes an electrode assembly including first and second electrode
tabs, a case accommodating the electrode assembly and having an opening, a cap platecoupled to the case at the opening of the case, a first current collector electricallyconnected to the first electrode tab of the electrode assembly, a second currentcollector electrically connected to the second electrode tab of the electrode assembly,and a sub-tab coupled to the first electrode tab or the second electrode tab of theelectrode assembly. The sub-tab is bent along a boundary between the sub-tab and thefirst or second current collector and contacts an outer periphery of the first or secondcurrent collector. The sub-tab is integrally formed with the first or second currentcollector.
