摘要：

properties of carbons iodated under various conditions were investigated. The iodine incorporation induced marked structural and electrochemical modification of activated carbons. These compounds resulted in a unique combination of high volumetric/gravimetric capacity. Specifically, the incorporation of halide leads to a 200-500% increase in volumetric, capacity of carbon materials. The resulting improvement is brought about through a modification of the non-Faradaic performance and development of a psuedocapacitive reaction at approximately 3.1 V Both of these reactions have contributed to the higher volumetric capacity and are investigated relative to the synthesis conditions of the compound.
