Aluminum electrolytic capacitor electrolytic capacitor. The properties of this aluminum oxide layer compared with tantalum pentoxide dielectric layer are given in the following table: After forming a dielectric oxide on the rough anode structures, a counter-electrode has to match the rough insulating oxide surface. This is provided by the electrolyte, which acts as the cathode electrode of an electrolytic capacitor. Electrolytes may be "non-solid" (wet, liquid) or "solid". Non-solid electrolytes, as a liquid medium that has an "ion conductivity" caused by moving ions, are relatively insensitive to voltage spikes or current surges. Solid electrolytes have an "electron conductivity", which makes solid electrolytic capacitors
Standard hydrogen electrode from the previous one it was given the name 'Standard Hydrogen Electrode'. In summary, The choice of platinum for the hydrogen electrode is due to several factors: The surface of platinum is platinized (i.e., covered with platinum black) to: Other metals can be used for building electrodes with a similar function such as the palladium-hydrogen electrode. Because of the high adsorption activity of the platinized platinum electrode, it's very important to protect electrode surface and solution from the presence of organic substances as well as from atmospheric oxygen. Inorganic ions that can reduce to a lower valency state at the
