Abstract
The present invention relates to a negative electrode including a multi-protective layer and a lithium secondary battery including the same, and the multi-protective layer prevents lithium dendrite growth on a surface of the electrode, and does not cause overpotential during charge and discharge since the protective layer itself does not function as a resistive layer, and therefore, is capable of preventing battery performance decline and securing stability when operating a battery.
