Abstract
In a secondary battery having an electrolyte injection hole having improved sealing structure to improve the safety of the can-type secondary battery and to prevent the electrolyte from leaking, the electrolyte injection hole is sealed by welding the sealing plate on top of the cap plate so that the electrolyte is prevented from flowing into the welded portion. Since no fine gap is created in the electrolyte injection hole, the electrolyte is prevented from flowing into the welded portion due to a capillary phenomenon and no pin hole caused by the electrolyte is formed in the welded portion.
