Abstract
An electrode and a lithium secondary battery comprising the same, in particularly an electrode comprising an electrode layer, a pre-lithiation prevention layer formed on the electrode layer, and a lithium layer formed on the pre-lithiation prevention layer, which is capable of greatly improving the problem of the reduction of irreversible capacity of a negative electrode while preventing fire caused by a lithiation reaction due to contact between lithium and silicon before assembling a cell, and a lithium secondary battery including the same.
