Abstract
Capacitor electrode materials were produced by Spark Plasma Sintering(SPS) with mixed carbon black and activated carbon powder Mixed powder was treated by Mechanical Milling(MM) with alumina balls varying treatment time in the range of from 0 to 12hr The characteristics of obtained samples were evaluated by Scanning electron microscope(SEM),X-ray diffraction(XRD) and four-probe method Following describes the results for samples sintered at a mixing ratio of CB101 activated carbon=1:1 SEM observation revealed that the MM treatment led uniform adhesion of CB101 particles on surface of the activated carbon particles From results of XRD measurements it was found that sintering process and variation of MM treatment time contributed little to the crystal structures of the samples Electrical conductivity of the sintered samples was higher than that of conventional electrode materials, and the conductivity m creased with MM treatment time
