Abstract
A method for regenerating a lithium secondary battery including a lithium resupply step in which a lithium resupply electrode is provided in the secondary battery, and the positive electrode is set as a counter electrode, and the lithium resupply electrode is set as a working electrode to charge lithium ions to the positive electrode through the lithium resupply electrode and a negative electrode discharging step in which, after the lithium ions are resupplied to the positive electrode through the lithium resupply step, the lithium resupply electrode is set as the counter electrode, and the negative electrode is set as the working electrode to completely discharge the negative electrode up to a discharge limit.
