NEGATIVE ELECTRODE PRE-LITHIATION METHOD

A negative electrode pre-lithiation 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. Then, 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 form a pre-lithiated negative electrode. The pre-lithiation solution comprises 3 vol % to 30 vol % of an organic carbonate compound substituted with halogen.
