Abstract
Proposed is a method of manufacturing a secondary battery. The method includes inserting an electrode assembly into a pouch, injecting an electrolyte into the pouch and aging, charging the electrode assembly, degassing to discharge gas from the pouch, discharging the electrode assembly, and charging to a shipment charge level. Since an anode active material is added to an anode material of a secondary battery through the method, there is an effect of further enhancing the reliability of the secondary battery in the manufacturing method of the secondary battery.
