Abstract

A feed-through, for example a battery feed-through for a lithium-ion battery or a lithium ion accumulator, has at least one base body which has at least one opening through which at least one conductor, for example a pin-shaped conductor, embedded in a glass material is guided. The base body contains a low melting material, for example a light metal, such as aluminum, magnesium, AlSiC, an aluminum alloy, a magnesium alloy, titanium, titanium alloy or steel, in particular special steel, stainless steel or tool steel. The glass material consists of the following in mole percent: 35-50% P2O5, for example 39-48%; 0-14% Al2O3, for example 2-12%; 2-10% B2O3, for example 4-8%; 0-30% Na2O, for example 0-20%; 0-20% M2O, for example 12-20%, wherein M is K, Cs or Rb; 0-10% PbO, for example 0-9%; 0-45% Li2O, for example 0-40% or 17-40%; 0-20% BaO, for example 5-20%; 0-10% Bi2O3, for example 1-5% or 2-5%.
