Electrode Assembly Having Enhanced Safety and Lithium Secondary Battery Comprising Same

An electrode assembly of the present invention comprises a cathode active material layer, a cathode current collector, a separator, an anode current collector, and an anode active material layer, which are stacked in order, wherein the current collectors have a plurality of through-holes formed to allow communication between the upper surface and the lower surface of the current collector. The electrode assembly of the present invention has the effect of preventing a rapid temperature increase if an internal short caused by damage to the separator occurs.
