The energy storage system according to claim 4, wherein said chemical compounds for binding the decomposition products of said at least one solvent are selected from a group consisting of Fe(II) compounds, Fe(III) compounds, Cu(II) compounds, Ag(I) compounds, and organic compounds. 6. The energy storage system according to claim 1, wherein said electronic sensor is at least one sensor selected from the group consisting of pressure sensors for detection of pressure and vibration and chemical sensors for detection of decomposition products of said at least one solvent. 7. The energy storage system according to claim 1, wherein said sensor is disposed on said housing. 8. The energy storage system according to claim 1, wherein said container is disposed in the interior of said housing. 9. The energy storage system according to claim 1, wherein said container is disposed on said housing. 10. The energy storage system according to claim 1, wherein said gas is CO2. 11. The energy storage system according to claim 1, wherein said chemical compounds are introduced into the interior by means of said gas when said closure of said container is opened. 12. The energy storage system according to claim 1, which further comprises a pressure equalization device for equalizing a pressure between the interior of said housing and the surroundings of the energy storage system disposed on said housing. 13. The energy storage system according to claim 12, wherein said pressure equalization device comprises a predetermined breaking point in said housing which, on an occurrence of overpressure in said housing, creates an opening in said housing for controlled equalization of the pressure in said interior of said housing. 14. The energy storage system according to claim 1, wherein said at least one solvent comprises acetonitrile. 15. The energy storage system according to claim 1, wherein said decomposition products of the solvent comprise compounds containing cyanide. 16. The energy storage system according to claim 1, wherein said electric component is a dual-layer capacitor. 17. An energy storage system, comprising an electric component having at least one solvent producing decomposition products;a housing having an interior, said housing enclosing said component in said interior; anda protective device configured to chemically bind the decomposition products of said at least one solvent;wherein said protective device includes an electronic sensor, a container with a closure, and chemical compounds for binding the decomposition products of said at least one solvent contained in said container;wherein said sensor is electrically coupled to said closure of said container;wherein said container includes an activatable device for collecting the reaction products between the chemical compounds and the decomposition products of said at least one solvent;wherein an activation of said activatable device is linked electronically to said electronic sensor; andwherein the activation of said activatable device includes an increase in a volume of said activatable device, for collecting the reaction products. 18. The energy storage system according to claim 17, wherein said closure of said container includes a valve for aspirating the decomposition products of the solvent from said interior into said container. 19. The energy storage system according to claim 17, wherein the activation of said activatable device generates a vacuum in the container.
