Abstract
A feed-through through a housing part of a housing, for example of a battery or a capacitor made of a metal, wherein the housing part has at least one opening, through which at least one conductor is fed in a glass or glass ceramic material, and wherein the conductor has at least two sections in the axial direction, a first section made of a first material, e.g. aluminium, and a second section made of a second material, e.g. copper, as well as a transition from the first to the second material, and wherein the transition from the first to the second material is located in the region of the glass or glass ceramic material, said glass or glass ceramic material being adapted to the metal of the housing in such a way that a compression glass-to-metal seal is formed.

A feed-through through a housing part of a housing of a storage device including a battery or a capacitor made of a metal including a light metal composed of at least one of aluminum, an aluminum alloy, AlSiC, magnesium, a magnesium alloy, titanium, steel, stainless steel, and high grade steel, said housing part has at least one opening, the housing has an outside and an inside, said feed-through comprising:
- at least one glass or glass ceramic material configured to seal the at least one opening of the housing part;
- and
- at least one conductor passing in the at least one glass or glass ceramic material through the at least one opening of the housing part, said at least one conductor including:
- at least two sections in an axial direction including a first section consisting of a first material and a second section consisting of a second material, said first material is a light material composed of at least one of aluminum, an aluminum alloy, AlSiC, magnesium, and a magnesium alloy, and
- a transition from the first material to the second material, said transition is located in a region of said at least one glass or glass ceramic material, wherein said at least one glass or glass ceramic material is selected such that a compression glass-to-metal seal is provided, wherein the second material is composed of copper or a copper alloy, wherein the first material is directed toward the outside of the housing and the second material is directed toward the inside of the housing.
A housing for an electric storage device including a battery or a capacitor, said housing having at least one opening, the housing having an outside and an inside, and comprising:
- a feed-through, including:
- at least one glass or glass ceramic material configured to seal the at least one opening of the housing;
- and
- at least one conductor passing in the at least one glass or glass ceramic material through the at least one opening of the housing, said at least one conductor including:
- at least two sections in an axial direction including a first section consisting of a first material and a second section consisting of a second material, said first material is a light material composed of at least one of aluminum, an aluminum alloy, AlSiC, magnesium, and a magnesium alloy, and
- a transition from the first material to the second material, said transition is located in a region of said at least one glass or glass ceramic material, wherein said at least one glass or glass ceramic material is selected such that a compression glass-to-metal seal is provided, wherein the second material is composed of copper or a copper alloy, wherein the first material is directed toward the outside of the housing and the second material is directed toward the inside of the housing.
A storage device including a battery or a capacitor, having a housing with at least one opening, the housing has an outside and an inside, said storage device comprising:
- a feed-through, including:
- at least one glass or glass ceramic material configured to seal the at least one opening of the housing;
- and
- at least one conductor passing in the at least one glass or glass ceramic material through the at least one opening of the housing, said at least one conductor including:
- at least two sections in an axial direction including a first section consisting of a first material and a second section consisting of a second material, said first material is a light material composed of at least one of aluminum, an aluminum alloy, AlSiC, magnesium, and a magnesium alloy, and
- a transition from the first material to the second material, said transition is located in a region of said at least one glass or glass ceramic material, wherein said at least one glass or glass ceramic material is selected such that a compression glass-to-metal seal is provided, wherein the first material is directed toward the outside of the housing and the second material is composed of copper or a copper alloy and is directed toward the inside of the housing.
