Pseudocapacitance capacitor, also k

Pseudocapacitance capacitor, also known as Faraday capacitor. Which is different from the electric double layer capacitor, they work on the principle of active substance deposited on the low potential electrode surface quasi-two-dimensional or two-dimensional space, causing the highly reversible chemical absorption / desorption or oxidation reducing capacitance generated by the reaction. Pseudo capacitance of the capacitor is the electrical energy into chemical energy and stored, so that the capacity is usually higher than the capacitance of the capacitor pseudo electric double layer capacity of several orders of magnitude. Faraday pseudo capacitance of the capacitor is an electrochemical process occurs only at the surface of the solid electrode, and occurs near the electrode surface and the inner solid. Therefore, when the same electrode area, the ratio of the capacitance of capacitor capacitance of pseudo electric double layer capacitor is 10 to 100 times greater than the capacitance, the energy density is also large.
