Noun
The part of a voltaic battery by which the electric current leaves substances through which it passes, or the surface at which the electric current passes out of the electrolyte; the negative pole; -- opposed to anode.

A cold-cathode version of the thyratron, which uses a pool of mercury for its cathode, is called an ignitron ; some can switch thousands of amperes. Source: Internet
Additional wires at cathode potential in the line of sight between the ion collector and the grid prevent this effect. Source: Internet
After the electrons reach the anode, they travel through the anode wire to the power supply and back to the cathode, so cathode rays carry electric current through the tube. Source: Internet
Alternatively, the electrons can be accelerated by the oscillating electric field induced by an alternating magnetic field of a coil, which results in a self-sustaining discharge without a cathode (radio frequency ion thruster). Source: Internet
After five to ten years, depending on the current used in the electrolysis, a cell must be rebuilt because of cathode wear. Source: Internet
