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
Electrode for advanced purposes in research and investigation. Electrode An electrode is an electrical conductor used to make contact with a nonmetallic part of a circuit (e.g. a semiconductor, an electrolyte, a vacuum or air). The word was coined by William Whewell at the request of the scientist Michael Faraday from two Greek words: "elektron", meaning amber (from which the word electricity is derived), and "hodos", a way. The electrophore, invented by Johan Wilcke, was an early version of an electrode used to study static electricity. An electrode in an electrochemical cell is referred to as either an "anode" or a
