1. A battery, comprising: a plurality of individual cells that are connected in parallel or in series with one another by cell connectors, each of the plurality of individual cells having pole contacts and a cell housing;a cooling apparatus for temperature control of the battery, wherein the cooling apparatus is a heat-conducting plate in physical and heat-conducting contact with each of the individual cells, wherein the pole contacts pass through bores or incisions in the heat-conducting plate, wherein the heat-conducting plate is interposed between the cell connectors and the cell housings of each of the individual cells,wherein the individual cells are attached to the cooling apparatus such that they are prestressed using the cell connectors,wherein each of the cell connectors includes an upper portion that engages with one of the pole contacts of one of the plurality of individual cells and a lower portion that presses against a top portion of the heat-conducting plate so that a bottom portion of the heat-conducting plate presses against a top portion of the individual cells,wherein the lower portion of the cell connectors has an omega-shaped longitudinal section. 2. The battery according to claim 1, wherein the cell connectors are formed in an elastic, resilient manner. 3. The battery according to claim 1, wherein a height of the cell connectors is larger than a height of the pole contacts of the respective individual cell projecting from the cooling apparatus. 4. The battery according to claim 1, wherein the cell connectors are in heat-conducting contact with the heat-conducting plate. 5. The battery according to claim 1, wherein an electrically insulating heat-conducting film is arranged between the cell connectors and the heat conducting plate. 6. The battery according to claim 5, wherein the heat-conducting film has recesses for passing the pole contacts through. 7. The battery according to claim 1, wherein a heat-conducting and electrically insulating molded body is arranged between the heat-conducting plate and the individual cells. 8. The battery according to claim 1, wherein the heat-conducting plate has a coolant channel structure. 9. The battery according to claim 1, wherein the cell housing of each of the individual cells has a honeycomb shape. 10. The battery according to claim 1, wherein the battery is a vehicle battery for a vehicle with a hybrid drive or a vehicle operated with fuel cells. 11. A battery, comprising: a plurality of individual cells that are connected in parallel or in series with one another by cell connectors, each of the plurality of individual cells having pole contacts and a cell housing;a cooling apparatus for temperature control of the battery, wherein the cooling apparatus is a heat-conducting plate in physical and heat-conducting contact with each of the individual cells, wherein the pole contacts pass through bores or incisions in the heat-conducting plate, wherein the heat-conducting plate is interposed between the cell connectors and the cell housings of each of the individual cells,wherein the individual cells are attached to the cooling apparatus such that they are prestressed using the cell connectors,wherein each of the cell connectors is provided with a spring element,wherein an upper portion of each of the cell connectors engages with one of the pole contacts of one of the plurality of individual cells, the spring element is interposed between the upper portion of the cell connectors and the heat-conducting plate, and a lower portion of the spring element presses against a top portion of the heat-conducting plate so that a bottom portion of the heat-conducting plate presses against a top portion of the individual cells,wherein the spring element is an s-shaped spring element that is applied to the corresponding cell connector in a form-fit and force-fit, locking manner. 12. The battery according to claim 11, wherein the respective spring element is formed at least of electrically insulating plastics. 13. The battery according to claim 11, wherein the cell connectors are in heat-conducting contact with the heat-conducting plate. 14. The battery according to claim 11, wherein an electrically insulating heat-conducting film is arranged between the cell connectors and the heat conducting plate. 15. The battery according to claim 14, wherein the heat-conducting film has recesses for passing the pole contacts through. 16. The battery according to claim 11, wherein a heat-conducting and electrically insulating molded body is arranged between the heat-conducting plate and the individual cells. 17. The battery according to claim 11, wherein the heat-conducting plate has a coolant channel structure. 18. The battery according to claim 11, wherein the cell housing of each of the individual cells has a honeycomb shape.
