Anode (Noun)

The negatively charged terminal of a voltaic cell or storage battery that supplies current.

Nouns denoting man-made objects.

The anode of a lithium-ion battery is typically made of graphite, which reacts with lithium ions to produce an electric current.
In a voltaic cell, the anode is the negatively charged terminal where oxidation occurs, releasing electrons into the external circuit.
The anode of a lead-acid battery is made of lead plates that are immersed in a sulfuric acid solution, which facilitates the chemical reaction that generates electricity.
During discharge, the anode of a nickel-cadmium battery releases electrons that flow through the external circuit to the cathode.
In electroplating, the anode is the source of the metal ions that are deposited onto the cathode, creating a thin layer of the desired metal.

A positively charged electrode by which electrons leave an electrical device.

Nouns denoting man-made objects.

The anode is connected to the positive terminal of the battery in this simple circuit.
In a vacuum tube, the anode is typically a metal plate that attracts electrons emitted by the cathode.
The anode of an electrochemical cell is where oxidation occurs, releasing electrons into the external circuit.
A common problem in fuel cells is the degradation of the anode over time, leading to reduced performance.
In a television picture tube, the anode serves as a positive terminal that accelerates electrons toward the phosphorescent screen.
