cath·ode

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

[Greek kathodos, descent : kat-, kata-, cata- + hodos, way, path.]

ca·thod′ic (kă-thŏd′ĭk) adj.
ca·thod′i·cal·ly adv.

cathode

(ˈkæθəʊd)
n
1. (General Physics) the negative electrode in an electrolytic cell; the electrode by which electrons enter a device from an external circuit
2. (General Physics) the negatively charged electron source in an electronic valve
3. (General Physics) the positive terminal of a primary cell
[C19: from Greek kathodos a descent, from kata- down + hodos way]
cathodal, cathodic, caˈthodical adj

cath•ode

(ˈkæθ oʊd)

n.
1. the electrode or terminal by which current leaves an electrolytic cell, voltaic cell, battery, etc.
2. the positive terminal of a voltaic cell or battery.
3. the negative terminal, electrode, or element of an electron tube or electrolytic cell.
[1825–35; < Greek káthodos a way down]
ca•thod′ic (kæˈθɒd ɪk) adj.

cath·ode

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

cathode

1. The electrode carrying the negative charge in a solution undergoing electrolysis.
2. A negative electrode.
