Abstract

A battery includes at least two sealing frames and at least one cell. The sealing frames include a base body defining an opening wherein the base body includes a first sealing surface embodied to be elastically compressible and positioned against opposite sides of a tapered area of the at least one cell.

First claim

What is claimed is:

1. A sealing frame for use in a battery comprising a base body, wherein the base body defines an enclosed perimeter that encompasses an opening, wherein a majority of a perimeter of a first face of the base body encompasses a first sealing surface and a majority of a perimeter of a second face of the base body opposite the first face encompasses a second sealing surface, wherein a majority of the base body has a complete rectangular cross section including the first face and the second face on opposite sides thereof and a minority portion of at least one of the first and second faces defining a recess therein, said recess extending across the at least one of the first and second faces and extending completely from an innermost edge of the base body that defines the opening to an outermost perimeter edge of the at least one of the first and second faces, wherein the first sealing surface and the second sealing surface is embodied so as to be elastically compressible.

2. The sealing frame according to claim 1 , wherein the first sealing surface and/or the second sealing surface is embodied as an elastically compressible layer, which is applied onto a non-elastic support body.

3. A sealing frame for use in a battery comprising a base body, wherein the base body defines an enclosed perimeter that encompasses an opening, wherein a majority of a perimeter of a first face of the base body encompasses a first sealing surface and a majority of a perimeter of a second face of the base body opposite the first face encompasses a second sealing surface located opposite to the first sealing surface, wherein a majority of the base body has a complete rectangular cross section including the first face and the second face on opposite sides thereof and a minority portion of at least one of the first and second faces defining a recess therein, said recess extending across the at least one of the first and second faces and extending completely from an innermost edge of the base body that defines the opening to an outermost perimeter edge of the at least one of the first and second faces, wherein the first sealing surface and the second sealing surface is embodied so as to be elastically compressible.

4. The sealing frame according to claim 1 , wherein provision is made in the first sealing surface and/or in the second sealing surface for a local area of higher elasticity.

5. The sealing frame according to claim 1 , wherein provision is made in the opening for bars, which encompass a thickness, which is less than the thickness of the base body.

6. The sealing frame according to claim 1 , wherein the base body is provided with an adhesive.

7. The sealing frame according to claim 1 , wherein a cooling unit is integrated into the sealing frame.

8. A battery comprising at least two sealing frames each comprising a base body, wherein the base body defines an enclosed perimeter that encompasses an opening extending all the way through the frames, wherein a majority of a perimeter of a first face of the base body encompasses a first sealing surface and a majority of a perimeter of a second face of the base body opposite the first face encompasses a second sealing surface located opposite thereto, wherein a majority of the base body has a complete rectangular cross section including the first face and the second face on opposite sides thereof and a minority portion of at least one of the first and second faces defining a recess therein, said recess extending across the at least one of the first and second faces and extending completely from an innermost edge of the base body that defines the opening to an outermost perimeter edge of the at least one of the first and second faces, wherein the first sealing surface and the second sealing surface is embodied so as to be elastically compressible, and at least one cell, wherein the cell is positioned between said at least two sealing frames, wherein the cell encompasses a thickened area, which extends into the openings of the base bodies thereof and wherein the cell encompasses a tapered area, on which the first and second sealing surfaces of said at least two sealing frames abut so as to form a seal, wherein an exhaust hood is arranged on the battery covering the recesses in said at least two sealing frames.

9. The battery according to claim 8 , wherein the sealing surfaces accommodate the tapered area at least area by area in a sandwich-like manner and in that they abut on one another so as to form a seal.

10. The battery according to claim 8 , wherein deviation plates of electrodes of the at least one cell, which project beyond the sealing frames, are accommodated between the sealing frames.

11. The battery according to claim 8 , wherein at least one sensor, which detects pressures, is arranged between the sealing frames.

12. The battery according to claim 8 , wherein the at least one cell is embodied as a coffee bag cell comprising a sealed seam.
