APPARATUS FOR PRE-LITHIATION OF NEGATIVE ELECTRODE AND METHOD FOR PRE-LITHIATION OF NEGATIVE ELECTRODE

An apparatus for pre-lithiating a negative electrode includes a pre-lithiation reactor having a pre-lithiation solution accommodated therein, a high-pressure chamber surrounding the pre-lithiation reactor, wherein an internal air pressure of the high-pressure chamber is configured to exceed atmospheric pressure, at least one lithium metal counter electrode disposed in the pre-lithiation solution, the lithium metal counter electrode being disposed to face a negative electrode receivable in the pre-lithiation solution in a state that the lithium metal counter electrode is spaced apart from the negative electrode by a predetermined interval, and a charge and discharge unit being connectable to the negative electrode and the lithium metal counter electrode to provide a circuit.
