Hyponyms (each of the following is a kind of "anode"):

plate (the positively charged electrode in a vacuum tube)

Holonyms ("anode" is a part of...):

electrolytic cell (a cell containing an electrolyte in which an applied voltage causes a reaction to occur that would not occur otherwise (such as the breakdown of water into hydrogen and oxygen))

electron tube; thermionic tube; thermionic vacuum tube; thermionic valve; tube; vacuum tube (electronic device consisting of a system of electrodes arranged in an evacuated glass or metal envelope)

Antonym:

cathode (a negatively charged electrode that is the source of electrons entering an electrical device)

Derivation:

anodal (of or at or relating to an anode)

Sense 2

Meaning:

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

Classified under:

Nouns denoting man-made objects

Hypernyms ("anode" is a kind of...):

pole; terminal (a contact on an electrical device (such as a battery) at which electric current enters or leaves)

Holonyms ("anode" is a part of...):

accumulator; storage battery (a voltaic battery that stores electric charge)

galvanic cell; primary cell; voltaic cell (an electric cell that generates an electromotive force by an irreversible conversion of chemical to electrical energy; cannot be recharged)

Antonym:

cathode (the positively charged terminal of a voltaic cell or storage battery that supplies current)

Derivation:

anodal (of or at or relating to an anode)

 Context examples 

The motion of charged particles in a colloid under the influence of an electric field; particles with a positive charge go to the cathode and negative to the anode.

(Electrophoresis, NCI Thesaurus)

An electrode placed between the cathode and anode of a vacuum tube to control the flow of electrons through the tube.

(Grid, NCI Thesaurus)

The peak accelerating voltage applied in an X-ray tube between the cathode and anode.

(Kilovolt Peak, NCI Thesaurus)

A lithium-ion battery charges and discharges as lithium ions move between two electrodes, called an anode and a cathode.

(Creating Better Lithium-Ion Batteries Made Possible with New Discovery, The Titi Tudorancea Bulletin)

This extracts the oxygen, and migrates the salt to an anode, where it can be easily removed.

(Scientists Find Way to Extract Oxygen from Moon Dirt, The Titi Tudorancea Bulletin)

This is because the bacterial cells were tightly attached to the paper fibers, which rapidly whisked the electrons away to the anode before oxygen could intervene.

(New Type of Battery Created from Paper, Fueled by Bacteria, The Titi Tudorancea Bulletin)

A battery consisting of a lithium anode and a cathode of iodine and poly-2-vinyl pyridine.

(Lithium Iodide Battery Device Component, NCI Thesaurus)

However, such a speedy charge rate would require a battery to rapidly take in 400 kilowatts of energy, a feat that current vehicles cannot accomplish because it risks lithium plating (the formation of metallic lithium around the anode), which would severely deteriorate battery life.

(Modern Battery Design Can Charge Electric Car in 10 Minutes, The Titi Tudorancea Bulletin)

In a traditional lithium-ion battery, the anode is made of graphite, while the cathode is composed of lithium cobalt oxide.
