an·ode

 (ăn′ōd′)
n.
1. A positively charged electrode, as of an electrolytic cell, storage battery, diode, or electron tube.
2. The negatively charged terminal of a primary cell or of a storage battery that is supplying current.

[Greek anodos, a way up : ana-, ana- + hodos, way.]

a·nod′ic (ə-nŏd′ĭk), a·nod′al (ə-nōd′l) adj.
a·nod′i·cal·ly, a·nod′al·ly adv.

anode

(ˈænəʊd)
n
1. (General Physics) the positive electrode in an electrolytic cell
2. (General Physics) Also called (esp US): plate the positively charged electrode in an electronic valve
3. (General Physics) the negative terminal of a primary cell. Compare cathode
[C19: from Greek anodos a way up, from hodos a way; alluding to the movement of the current to or from the positive pole]
anodal, anodic adj

an•ode

(ˈæn oʊd)

n.
1. the electrode or terminal by which current enters an electrolytic cell, voltaic cell, battery, etc.
2. the negative terminal of a voltaic cell or battery.
3. the positive terminal, electrode, or element of an electron tube or electrolytic cell.
[1834; < Greek ánodos upward path =an- an-3 + hodós way, road]
an•od′ic (-ˈɒd ɪk) adj.

an·ode

(ăn′ōd′)
1. The positive electrode in an electrolytic cell, toward which negatively charged particles are attracted. The anode has a positive charge because it is connected to the positively charged end of an external power supply.
2. The negative electrode in a voltaic cell, such as a battery, toward which positively charged particles are attracted. The anode gets its negative charge from the chemical reaction that happens inside the battery, not from an external source. Compare cathode.

anode

1. Electrode carrying the positive charge in a solution undergoing electrolysis.
2. A positive electrode.
