PRE-LITHIATION APPARATUS

Provided is a pre-lithiation apparatus which prevents an electrode from being damaged by the byproducts produced by contact between a lithium source, such as a lithium metal sheet or lithium metal powder, and an electrolyte for pre-lithiation. The pre-lithiation apparatus includes two reaction vessels of a first reaction vessel and a second reaction vessel, wherein the electrolyte solution of the first reaction vessel and the electrolyte solution of the second reaction vessel are linked to each other by a salt bridge, a negative electrode to be pre-lithiated is dipped at least partially in the electrolyte solution of the first reaction vessel, and a lithium source capable of supplying lithium ions is dipped at least partially in the electrolyte solution of the second reaction vessel.
