    摘要: A method for producing a halogenated activated carbon material includes heating a natural, non-lignocellulosic carbon precursor in an inert or reducing atmosphere to form a first carbon material, mixing the first carbon material with an inorganic compound to form a mixture, heating the mixture in an inert or reducing atmosphere to incorporate the inorganic compound into the first carbon material, removing the inorganic compound from the first carbon material to produce an activated carbon material, and treating the activated carbon material with a halogen source to form a halogenated activated carbon material. The halogenated activated carbon material is suitable to form improved carbon-based electrodes for use in high energy density devices.

    摘要: An electro-chemical double layer capacitor comprises positive and negative electrodes, where the carbon material that is incorporated into the positive electrode is halogenated carbon material, while the carbon material that is incorporated into the negative electrode is un-halogenated carbon material. Further, the carbon material incorporated into each respective electrode can have a distinct pore size distribution. A pore volume ratio of the carbon material incorporated into the positive electrode is greater than a pore volume ratio of the carbon material incorporated into the negative electrode. The pore volume ratio R is defined as R=V1/V, where V1 is a total volume of pores having a pore size of less than 1 nm, and V is a total volume of pores having a pore size greater than 1 nm.
