Electrochemical Characteristics of Carbonaceous Materials for Energy Storable Electrode Fabrication

Abstract

Photo-capacitor electrodes are attracting great attention because of their high capacitance and potential applications in electronic devices. Carbon capacitor, active carbon capacitor and its combination will be fabricated using a sandwich method as carbonaceous material on each type of storable electrode with 20×15[㎜] cell size. Carbon/active carbon cell was fabricated using sol-gel process with 120[℃] dry temperature in 2hour and using sintering process with 500[℃] in 2hour. The effect of sintering temperature on carbon properties was also investigated with an X-ray diffraction technique to get the best sintering temperature. The detail of the fabrication process will be explained. Active carbon as carbonaceous material has a better capacitance in storable electrode with mean thickness 32[μm] and with particle size 1[㎛] to 4.5[㎛] in 20×15[㎜] sample size of storable electrode.
