Abstract: IMPROVED POLYOXOMETALATE-MODIFIED CARBON ELECTRODES AND USES THEREFOR Improved activated carbon electrodes are disclosed which electrodes have increased charge storage capacity and reduced leakage current. Such improved electrodes are incorporated into energy storage devices such as electric double layer capacitors. The improved charge storage capacity is due to the adsorption of polyoxometalate compounds onto the activated carbon and reduced leakage current is achieved by stabilizing the polyoxometalate compounds within the activated carbon through the use of a compound capable of generating at least one ionic site.
