| 内容記述 | The use of the pulsed electro acoustic (PEA) method allowed us to perform the direct observations of spatio-temporal charge distributions in EDLCs based on polarizable nanoporous carbonaceous electrode. The negative charge density became the maximum, about -198 C/m3 at the region where was near to anode layer in EDLCs for case of dc voltage 2.5 V, while the positively charged density became the maximum, about 60.1 C/m3 at the region where it was located around the cathode layer. The behavior of negative and positive charges measured by the PEA method reflected the hetero-charges distribution in EDLCs. The performance of the sample was found to be better in terms of the capacitance (Cs) with a maximum value of 55.4 F/g. | |||||
