Definition of anode in English:

anode

nounˈanəʊdˈænoʊd

1The positively charged electrode by which the electrons leave an electrical device.
The opposite of cathode
Example sentencesExamples
- Meanwhile, copper atoms in the positive anode give up electrons and dissolve into the electrolyte solution as copper ions.
- Gaseous hydrogen and oxygen flow separately around either side of two electrolytic plates serving as anodes and cathodes.
- As soon as the circuit of the lead storage battery cell is closed and the cathode and anode are connected, the reaction begins and electrons flow from the anode to the cathode.
- At one electrode, the anode, molecules of hydrogen gas break down into electrons and positively charged hydrogen ions.
- One is a photosensitive cathode which emits electrons when exposed to light and the other is an anode which is maintained at a positive voltage with respect to the cathode.
1. 1.1 The negatively charged electrode of an electrical device, such as a primary cell, that supplies current.
  Example sentencesExamples
  Because electrons originate at the anode in a voltaic cell, the anode has a (-) charge; electrons enter the cathode, which has a (+) charge.
  The rods serve as negative electrodes, or anodes, and the tube serves as a positive electrode, or cathode.
  The fuel cell also needs moisture in the electrolyte as well as water at the anode to control the supply of methanol.
  Current can only flow from the anode to the cathode, but not the other direction.
  Oxygen enters at the cathode, where it combines with electrons and is split into ions that travel through the electrolyte to react with fuel at the anode.

Derivatives

anodal

adjectiveəˈnəʊd(ə)l

After each hour, the current was interrupted, and the entire contents of anodal and cathodal chamber were withdrawn and replaced by fresh receiver solution.
Example sentencesExamples
- Allozymes of an isozyme were designated as either fast or slow, with the most anodal designated as fast and the slower allozyme as slow.
- Loci and alleles were numbered consecutively from the most anodal form.
- The solution is poured over thin gauze placed on a stainless steel anodal plate.
- Cathodal and anodal shock electrodes (denoted as C and A) were located at fiber ends.

anodic

adjectiveaˈnɒdɪkænˈɑdɪk

Glass covers were bonded over the microchannels using anodic bonding.
Example sentencesExamples
- The inert nature of the anodic coating provides excellent heat resistance.
- Although the actual chemical reactions taking place within a battery are very complex, the major cathodic and anodic reactions can be idealized based on a knowledge of the parts of a battery and their electrochemical function.
- Surface properties of titanium and its alloys can be modified by anodic oxidation treatment, which covers the entire surface with a thin but compact oxide film.
- Such corrosion occurs when the heavy metal, the heavy metal basic salts or both plate out to form active cathodes on the anodic magnesium surface.

Origin

Mid 19th century: from Greek anodos 'way up', from ana 'up' + hodos 'way'.
