METHOD FOR MANUFACTURING LEAD TAB FOR SECONDARY BATTERY AND LEAD TAB FOR SECONDARY BATTERY MANUFACTURED THEREBY

A method of manufacturing a lead tab for a secondary battery comprises the steps of: (a) providing heat of a predetermined temperature or higher to the lead tab having a processing pattern formed on each of top and bottom surfaces to form an oxide film on the surfaces on which the processing pattern is formed; and (c) coating the surfaces on which the processing pattern is formed by spraying an adhesive solution, wherein (b) a step of controlling a temperature of the lead tab is provided between steps (a) and (c) so that the adhesive solution may be coated on the surface of the lead tab in an optimized state at step (c).
