Abstract

The present disclosure relates to a terminal part (100) for a cylindrical secondary cell. The terminal part (100) comprises a shaft (110) configured to extend axially through a casing of the secondary cell, wherein a first end (113) of the shaft (110) is configured to provide an electrical connection with an electrode roll in the secondary cell; and a head (120) arranged at a second end (111 ) of the shaft (110), configured to form an external terminal for the cylindrical secondary cell. The shaft (110) comprises a ridged shaft portion (114) on a lateral surface of the shaft (110), wherein said ridged shaft portion (114) comprises at least one ridge extending around the lateral surface (110b) of the shaft (110).
