Method for pre-lithiating negative electrode

The present invention relates to a method for pre-lithiating a negative electrode, comprising the steps of: manufacturing a negative electrode by forming a negative electrode active material layer including a negative electrode active material on a negative electrode current collector; manufacturing a pre-lithiation battery cell comprising the negative electrode and a lithium metal counter electrode, and dipping the pre-lithiation battery cell in a pre-lithiation solution; and charging the pre-lithiated cell with a constant voltage to pre-lithiate the negative electrode, wherein the pre-lithiation solution includes from 3% to 30% by volume of an organic carbonate compound substituted with a halogen atom. 本发明涉及一种预锂化负极的方法，包括以下步骤：通过在负极集电器上形成包括负极活性材料的负极活性材料层来制造负极；制造包括所述负极和锂金属对电极的预锂化电芯，并将所述预锂化电芯浸渍在预锂化溶液中；和用恒定电压充电所述预锂化电芯以预锂化所述负极，其中所述预锂化溶液包括3体积％至30体积％的用卤素原子取代的有机碳酸酯化合物。
