A battery includes at least two battery cells arranged adjacent to one another and each arranged in a battery cell housing. Each battery cell has at least one battery cell terminal. The battery also includes one degasification element per battery cell. Each degasification element is arranged within the battery cell housing associated with the respective battery cell and is configured to discharge gases generated within the respective battery cell from the respective battery cell in the presence of a predetermined gas pressure. The battery also includes a cover configured to cover at least a part of the surfaces of the battery cells and cover the degasification elements of the battery cells in air-tight fashion. The cover has, in each case in a region of the degasification elements, predetermined breaking points assigned to the degasification elements.

1. A battery, comprising: at least two battery cells arranged adjacent to one another and each arranged in a battery cell housing, each battery cell having at least one battery cell terminal;one degasification element per battery cell, each degasification element arranged within the battery cell housing associated with the respective battery cell and configured to discharge gases generated within the respective battery cell from the respective battery cell in a presence of a predetermined gas pressure; anda cover configured to cover at least a part of surfaces of the battery cells and cover the degasification elements of the battery cells in air-tight fashion,wherein: the cover is composed at least partially of at least one of a chemically resistant material, a heat-insulating material and a heat-reflective material;the cover is composed at least partially from at least one of an aerogel material and a ceramic material; andthe at least one of an aerogel material and a ceramic material of the cover defines a respective predetermined breaking point for each of the degasification elements, each predetermined breaking point in a region of a corresponding degasification element. 2. The battery according to claim 1, wherein each predetermined breaking point is configured to break when gas is discharged through the degasification element associated with the respective predetermined breaking point. 3. The battery according to claim 1, wherein the predetermined breaking points are perforations within the cover. 4. The battery according to claim 1, wherein the predetermined breaking points are local reductions in a thickness of the cover. 5. The battery according to claim 4, wherein the predetermined breaking points are local minimizations of the thickness of the cover. 6. The battery according to claim 1, wherein the predetermined breaking points are formed as island-like sections of the cover which each at least partially cover the degasification elements assigned to the predetermined breaking points. 7. The battery according to claim 1, wherein the cover is formed as a plate. 8. The battery according to claim 1, wherein the cover has cutouts through each of which one battery cell terminal of the battery cells covered by the cover can extend. 9. A motor vehicle, comprising: a drive system; anda battery, including: at least two battery cells arranged adjacent to one another and each arranged in a battery cell housing, each battery cell having at least one battery cell terminal;one degasification element per battery cell, each degasification element arranged within the battery cell housing associated with the respective battery cell and configured to discharge gases generated within the respective battery cell from the respective battery cell in a presence of a predetermined gas pressure; anda cover configured to cover at least a part of surfaces of the battery cells and cover the degasification elements of the battery cells in air-tight fashion,wherein: the cover is composed at least partially of at least one of a chemically resistant material, a heat-insulating material and a heat-reflective material;the cover is composed at least partially from at least one of an aerogel material and a ceramic material; andthe at least one of an aerogel material and a ceramic material of the cover defines a respective predetermined breaking point for each of the degasification elements, each predetermined breaking point in a region of a corresponding degasification element, andwherein the battery is connected to the drive system of the motor vehicle. 10. A battery, comprising: at least two battery cells arranged adjacent to each other and each arranged in a respective battery cell housing, each battery cell having at least one battery cell terminal;one degasification element per battery cell, each degasification element arranged within the battery cell housing associated with the respective battery cell and configured to discharge gases generated within the respective battery cell from the respective battery cell in a presence of a predetermined gas pressure; anda rigid plate that forms a cover configured to cover at least a part of surfaces of the battery cells and cover the degasification elements of the battery cells in air-tight fashion,wherein the cover has a respective predetermined breaking point assigned to each the degasification elements, each predetermined breaking point in a region of a corresponding degasification element. 11. The battery according to claim 10, wherein each predetermined breaking point is configured to break in response to gas being discharged through the degasification element associated with the respective predetermined breaking point. 12. The battery according to claim 10, wherein the predetermined breaking points are defined by perforations within the cover. 13. The battery according to claim 10, wherein the predetermined breaking points defined by local reductions in a thickness of the cover. 14. The battery according to claim 13, wherein the local reductions in the thickness of the cover are local minimizations of the thickness of the cover. 15. The battery according to claim 10, wherein the plate further defines a plurality of cutouts, the at least one terminal of each of the battery cells extending through a respective one of the cutouts. 16. The battery according to claim 10, wherein the plate is formed from material that is at least one of chemically resistant, heat insulating, and heat reflective. 17. The battery according to claim 16, wherein the predetermined breaking points of the cover are formed from at least one of an aerogel material and a ceramic material.
