A METHOD OF PRE-LITHIATING A NEGATIVE ELECTRODE

The present invention relates to a pre-lithiating a negative electrode method comprising the steps of: manufacturing a negative electrode by forming, on a negative electrode current collector, a negative electrode active material layer comprising a negative electrode active material; manufacturing a pre-lithiation cell, which comprises the negative electrode and a lithium metal counter electrode, and impregnating the pre-lithiation cell with a pre-lithiation solution; and charging the pre-lithiation cell with a constant voltage to pre-lithiate the negative electrode, wherein the pre-lithiation solution comprises 3-30 vol% of an organic carbonate compound substituted with a halogen atom.
