Abstract (en)

[origin: WO2021185648A1] The invention relates to an electrical device, in particular an electrical storage device or sensor housing, preferably a battery, in particular a microbattery or capacitor, having a feedthrough, in particular through a housing part of a housing of the device made of a metal, in particular iron, iron alloys, iron-nickel alloys, iron-nickel-cobalt alloys, KOVAR, steel, stainless steel, stainless steel, aluminium, an aluminium alloy, AlSIC, magnesium, a magnesium alloy or titanium or a titanium alloy, wherein the housing part has at least one opening as part of the feedthrough, wherein the opening extends about an axis and a first region of the housing part comprises the opening and a second region of the housing part is adjacent to the opening and the opening receives a conductive material in particular a conductor in a glass or glass ceramic material. The invention is characterised in that the first region of the housing part has a width W that is essentially perpendicular to the axis of the opening and the width W of the first region is always greater than the thickness D, D of the second region and the conductive material has a first expansion coefficient α1, and the glass or glass-ceramic material has a second expansion coefficient α2 and the housing part has a third expansion coefficient α3, the third expansion coefficient α3 always being greater than the second coefficient of expansion α2.
