In electronics, an anode is the positive electrode in a cell such as a battery. Compare cathode.
[technical]
anode in British English
(ˈænəʊd)
noun
1.
the positive electrode in an electrolytic cell
2. Also called (esp US): plate
the positively charged electrode in an electronic valve
3.
the negative terminal of a primary cell
Compare cathode

anodal (eɪˈnəʊdəl) or anodic (əˈnɒdɪk)
adjective
Word origin
C19: from Greek anodos a way up, from hodos a way; alluding to the movement of the current to or from the positive pole
anode in American English
(ˈænˌoʊd)
noun
1.
in an electroplating cell, the positively charged electrode, toward which current flows
2.
in an electron tube, the principal electrode for collecting electrons, operated at a positive potential with respect to the cathode
3.
in a battery that is a source of electric current, as a dry cell or storage battery, the negative electrode from which the electrons are released to the external circuit

noun
(Electrical engineering: Circuits)
The anode of an electrical device is the positive electrode, which is the element that receives the flow of electrons.
Radio valves of the vacuum tube variety had anodes and cathodes through which current passed.
When a positive voltage is applied between the anode and cathode, current will flow through the diode, provided the voltage is greaterthan around 0.7V.
The anode of an electrical device is the positive electrode, which is the element that receivesthe flow of electrons.
