PRE-LITHIATION APPARATUS

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 a first reaction vessel comprising a first electrolyte and a first organic solvent and a second reaction vessel comprising a second electrolyte and a second organic solvent, wherein the first electrolyte of the first reaction vessel and the second electrolyte 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 first electrolyte of the first reaction vessel, and a lithium source capable of supplying lithium ions is dipped at least partially in the second electrolyte of the second reaction vessel.
