POLYOXOMETALATE MODIFIED CARBON ELECTRODES AND USES THEREFOR

摘要

POLYOXOMETALATE-MODIFIED CARBON ELECTRODES AND USES THEREFOR Improved activated carbon electrodes are disclosed, which electrodes have increased charge storage capacity. Such improved electrodes are incorporated into energy storage devices such as electrical double layer capacitors. The improved charge storage capacity is due to the adsorption of polyoxometalate compounds into the activated carbon, which compounds are capable of reversible redox reactions and so provide a secondary charge storage mechanism without decreasing the charge storage ability of the activated carbon.
