Meanings

Plural: anodes

Noun

a positively charged electrode by which electrons leave an electrical device
the negatively charged terminal of a voltaic cell or storage battery that supplies current
An electrode, of a cell or other electrically polarized device, through which a positive current of electricity flows inwards (and thus, electrons flow outwards). It can have either a positive or a negative voltage with respect to cathode of the same polarized device (depending on whether the device is a load or a source, respectively).
(by extension) The electrode at which chemical oxidation of anions takes place, usually resulting in the erosion of metal from the electrode.
The electrode which collects electrons emitted by the cathode in a vacuum tube or gas-filled tube.
That electrode of a semiconductor device which is connected to the p-type material of a p-n junction.

Origin / Etymology

From Ancient Greek ἀνα- (ana-, “up”) and ὁδός (hodós, “path”), forming the New Greek compound ἄνοδος (ánodos). Coined by English polymath William Whewell in 1834 for Michael Faraday, who introduced it later that year.
