Abstract: The present application relates to an electrode assembly and a secondary battery. The electrode assembly includes a cell and a protective layer. The cell includes a cell body and an electrode tab protruding from a top surface of the cell body. In a length direction of the cell, at least one end of the protective layer extends beyond the height at which the anode electrode in the cell body protrudes at the end, and the extended dimension is no more than 3 mm. As such, the burr of the anode electrode of the cell body is wrapped by the protective layer, which alleviates the phenomenon that the burr on the anode electrode pierces the package bag and chemically reacts with the aluminum layer of the package bag, thereby reducing the risk of leakage of the package bag.
