摘要： A metal/air button cell includes a cell cup having at least one inlet opening via which atmospheric oxygen can enter the interior, the cell cup has an inner side facing the interior, and an oppositely directed outer side, an air cathode is in the form of a cathode disk with a circumferential cathode disk periphery, the air cathode includes a metal collector structure, the cathode disk is arranged such that the cathode disk periphery bears along a circumferential contact zone against the inner side of a cladding region, the cell cup has, on its outer side, at least one recess made by impression and becomes visible as a raised portion on the inner side, and the at least one recess is made in the outer side such that the raised portion exerts a pressure against the cathode disk periphery in the region of the contact zone.
