47. What is the electric double layer capacitor? What are its characteristics?

Electric double layer capacitor is based on the German physicist Helmholtzs double layer interface based on the theory of a new capacitor. As we all know, into the electrolyte solution in the metal electrode surface and 47 datasheet and the surface will appear on both sides of the opposite sign of the excess charge, so that the potential difference and 47 price and white. So, if you insert two electrodes while the electrolyte and 47 suppliers and the electrolyte solution during the decomposition of applying a voltage less than the voltage, when the electrolyte in the positive and negative ions in the electric field rapidly toward the poles movement, and were in two electrodes on the surface charge layer close, that is, double layer, it forms the electric double layer capacitor in the electric and traditional media in the electric field produced by polarization charge is similar, resulting in capacitance effects. Closely similar to flat electric double layer capacitor, but because of the close spacing of the charge layer capacitance than the average distance between din charge layer is much smaller, and thus has a greater capacity than ordinary capacitors.

double-layer capacitors and aluminum electrolytic capacitors larger than resistance, therefore, in the case of no load resistance directly charged. If over-voltage charging situations, double-layer capacitors will be open and will not damage the device, the characteristics and electrolytic capacitor voltage breakdown are different. Meanwhile, the electric double layer capacitors and rechargeable battery, charging current can be limited, and the number of charge cycles up to 106 or more, so not only with double-layer capacitance capacitance characteristics, but also has the characteristics of the battery, is a cross between battery and capacitor between the new special components.
