Abstract

A feed-through, in particular a feed-through which passes through part of a housing, in particular a battery housing, for example made of metal, in particular light metal, for example aluminum, an aluminum alloy, AlSiC, magnesium, an magnesium alloy, titanium, a titanium alloy, steel, stainless steel or high-grade steel. The housing part has at least one opening through which at least one conductor, in particular an essentially pin-shaped conductor, embedded in a glass or glass ceramic material, is guided. The base body is, for example, an essentially annular-shaped base body and is hermetically sealed with the housing part such that the helium leakage rate is smaller than 1*10−8 mbar l/sec.
