A thin, flat and flexible galvanic element, its metallic housing including a foil fabricated from a copper material having a copper content of at least about 95% by weight and a light-metal alloying additive, where the copper and alloying light metal differ in atomic number by at least 15, but no more than 26, and have melting points that differ by at least about 400° C., but no more than about 950° C., the alloying metal is monovalent to trivalent in compounds and modifies the face-centered cubic hard-sphere packing of the copper during alloying such that its mass density of about 8.94 g/cm3 is altered by at least about 0.03 g/cm3, and the foil has an adhesive coating on its side facing the interior of the housing.
