  • Patent number: 11996563
    Abstract: Provided is a secondary battery which includes an electrode assembly having an electrode tab extended from an electrode current collector, wherein the electrode tab is provided with an insulation coating layer containing an inorganic filler and a binder, the binder has an electrolyte uptake more than 0% and less than 50%, and the electrolyte uptake is determined by a predetermined method. In the secondary battery according to the present disclosure, the insulation coating layer provided in the electrode tab includes a binder having a low electrolyte uptake, and thus the insulation coating layer has improved adhesion and is prevented from detachment from the electrode tab. As a result, it is possible to maintain an excellent insulation state and to minimize an internal short-circuit in a secondary battery, thereby ensuring safety.
