Abstract

Various embodiments of the present invention relate to a secondary battery having symmetric multi-tabs, and the technical problem to be solved is providing a secondary battery capable of increasing the insulation level of first and second multi-tabs by forming the first and second multi-tabs of first and second electrode assemblies to be symmetric to each other. To this end, the present invention provides a secondary battery comprising: a case; a first electrode assembly accommodated inside the case and having first multi-tabs; a second electrode assembly accommodated in parallel with the first electrode assembly inside the case and having second multi-tabs; and a cap plate closing the case and having electrode terminals electrically connected to the first and second multi-tabs of the first and second electrode assemblies, wherein the first and second multi-tabs are formed so as to be symmetrical with respect to the boundary area between the first and second electrode assemblies.
