The terms anode and cathode are not defined by the voltage polarity of electrodes, but are usually defined by the direction of current through the electrode. An anode usually is the electrode of a device through which conventional current (positive charge) flows into the device from an external circuit, while a cathode usually is the electrode through which conventional current flows out of ...
A plate, usually called anode in Britain, is a type of electrode that forms part of a vacuum tube. [1] It is usually made of sheet metal, connected to a wire which passes through the glass envelope of the tube to a terminal in the base of the tube, where it is connected to the external circuit.
For systems with an anode or cathode that is sensitive to non-uniform current density, non-equal numbers of cathodes and anodes can be used; the 2:1 hexagonal design allows for a uniform current density at the anode but a non-uniform current distribution at the cathode. Performance can be increased through changing the shape of the poles.
Anodic bonding is commonly used to seal glass to silicon wafers in electronics and microfluidics. Anodic bonding, also known as field assisted bonding or electrostatic sealing, [1] is mostly used for connecting silicon/glass and metal/glass through electric fields. The requirements for anodic bonding are clean and even wafer surfaces and atomic ...
(While this may be true with the currently commercially available technologies today, high throwpower anodic systems are known and have been used commercially in the past.) Oxidation only occurs at the anode, and thus staining and other problems which may result from the oxidation of the electrode substrate itself is avoided in the cathodic ...
[1] [2] [3] The working electrode is often used in conjunction with an auxiliary electrode, and a reference electrode in a three-electrode system. Depending on whether the reaction on the electrode is a reduction or an oxidation , the working electrode is called cathodic or anodic , respectively.
