ELECTRODE ASSEMBLY AND SECONDARY BATTERY COMPRISING THE ELECTRODE ASSEMBLY

An electrode assembly according to the embodiment includes a first electrode, a second electrode, and a separator between the first electrode and the second electrode. The first electrode comprises a first substrate including a first uncoated portion extending upwardly, a first active material layer on the first substrate, and a first protective layer on the first uncoated portion. The second electrode comprises a second substrate including a second uncoated portion extending downwardly, a second active material layer on the second substrate, and a second protective layer on the second uncoated portion. The first protective layer and the second protective layer are disposed on the first active material layer, the second active material layer, and the separator.
