anode

(ăn`ōd), electrodeelectrode,
terminal through which electric current passes between metallic and nonmetallic parts of an electric circuit. In most familiar circuits current is carried by metallic conductors, but in some circuits the current passes for some distance through a nonmetallic conductor.

anode

[′a‚nōd]
(electricity)
The terminal at which current enters a primary cell or storage battery; it is positive with respect to the device, and negative with respect to the external circuit.
(electronics)
The collector of electrons in an electron tube. Also known as plate; positive electrode.
In a semiconductor diode, the terminal toward which forward current flows from the external circuit.
(physical chemistry)
The positive terminal of an electrolytic cell.

anode

In an electric system to protect underground iron pipes or structures from electrochemical action, a metallic rod which is driven in the ground; direct current is passed through the rod to the earth, and then through the iron pipe or structure, in a direction opposite to that resulting from the electrochemical properties of the soil.

anode

1. the positive electrode in an electrolytic cell
2. the positively charged electrode in an electronic valve
3. the negative terminal of a primary cell

anode

The terminal on a device that receives current. It may be considered positive or negative depending on the application. See cathode.

Cathodic protection specialists routinely employ vacuum excavators to access buried metal pipe and other structures in order to install or replace anodes that protect pipe from active corrosion, a natural process that affects all metallic structures.
This "uses up" the electrons, allowing more to keep flowing from the anode to the cathode.

Silicon anodes could store 10 times more charge than the graphite anodes in today's rechargeable lithium-ion batteries, but they also have major drawbacks: The brittle silicon swells and falls apart during battery charging, and it reacts with the battery's electrolyte to form gunk that coats the anode and degrades its performance.
The upgrade was made possible with the successful installation of the first 1,600mm-long anode in Pot Line 5 - a significant breakthrough that's geared to place Alba amongst the leaders in pot line current and productivity through effective deployment of advanced AP3X smelting technology.
Lithium-ion batteries charge through a chemical reaction in which lithium ions are sent between two ends of the battery, the anode and the cathode.
