Abstract
Capacitors, including supercapacitors, are described wherein the electrode contains at least one modified carbon product, wherein the modified carbon product is at least one carbon product having attached at least one organic group. The use of the modified carbon product in the electrodes for capacitors preferably leads to improved capacitance and/or lower internal resistance of the capacitor. Further, the use of modified carbon products in the electrodes for capacitors permits easier manufacturing steps for the production of capacitors.
