Beschreibung
Zusammenfassung:	The present invention provides a method of pre-lithiating an electrode for a secondary battery, the method including: a first step of bringing a lithium metal directly into contact with an electrode in an electrolyte and applying a pressure to the electrode to be pre-lithiated; and a second step of removing the lithium metal and then applying a pressure to the pre-lithiated electrode to perform a stabilization process. The electrode for the secondary battery after going through the pre-lithiation step provided in the present invention can relieve the volume change of the electrode and reduce the contact loss of the electrode.
