Printing Method For Preventing Corrosion, And Battery Cell Manufactured Using Same

Abstract: The present invention provides a method for printing a coating material for preventing corrosion, and a battery cell manufactured using same. According to the method, the coating material can be locally printed onto the minimum area in which a coating for anti-corrosion is required at the front end of a crimping part of a battery can with a fracture surface. The coating material is a thermosetting resin or a sealant, and can be cured by heat in an activation step of a subsequent cell without undergoing a separate curing step. The coating material can be printed onto the front end of the crimping part through reverse-transcribing (printing), onto the local area, the coating material having a predetermined pattern transferred to the surface of a flexible pad.
