Abstract

A cylindrical secondary cell (100) is disclosed. The cell (100) comprises a cylindrical housing (102) comprising a first end (104) and an opposing second end (106), a first terminal (110) at the first end (104), and a second terminal electrically insulated from the first terminal (110). The first end (104) further comprises a venting region (120) configured to rupture to provide an opening in the first end (104) if the pressure inside the cylindrical housing reaches a threshold value. The venting region (120) extends between an inner boundary (122) and an outer boundary (124) and extends
