Title:
LITHIUM SECONDARY BATTERY REGENERATION METHOD
Document Type and Number:
WIPO Patent Application WO/2019/013536
Kind Code:
A1
Abstract:
A lithium secondary battery regeneration method according to the present invention is a method for regenerating a secondary battery comprising: an electrode assembly in which electrodes including a positive electrode and a negative electrode and a separator are alternately stacked together; and a battery case for receiving the electrode assembly. The method comprises: a lithium resupply step of further providing the secondary battery with a lithium resupply electrode, and setting the positive electrode as a counter electrode and setting the lithium resupply electrode as a working electrode to supply lithium ions to the positive electrode through the lithium resupply electrode; and a negative electrode discharge step of, after resupplying lithium ions to the positive electrode through the resupply step, setting the lithium resupply electrode as a counter electrode and setting the negative electrode as a working electrode to fully discharge the negative electrode up to a discharge limit.
