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