cath·ode (Ca, C),

(kath'ōd),
The negative pole of a galvanic battery or the electrode connected with it; the electrode toward which positively charged ions (cations) migrate and are reduced, and into which electrons are fed from their source (anode or generator). Compare: anode.
Synonym(s): negative electrode
[G. kathodos, a way down, fr. kata, down, + hodos, a way]
