A knob found on a battery

Usage examples of anode.

The entire pump is placed in a strong magnetic field, and a potential of about five kilovolts is impressed between the cathodes and the anode to accelerate electrons present in the residual gas toward the anode.

These chemists electrolyse either pure calcium chloride, or a mixture of this salt with fluorspar, in a graphite vessel which serves as the anode.

The whole operation took only fifteen minutes, and the shiny new screws were fully attached, and new protective anodes set in place.

Before they could use the Janus Gate to try to rescue Captain Kirk from his own past, before Sulu and Chekov had even been retrieved from the healing chamber where the Janus Gate had sent them, a horde of metallic insects had plunged down into their midst, using metallic claws with stinging electrical anodes to herd them all to the edge of the cavern.

The San Shin Building was one of the few anodes on which the various occupying powers collected, and one could feel the reserve and mistrust underlying their superficial camaraderie.

Also the in-phase voltage can not better be obtained than by exciting the phasing anode with some of the main-line power.

The jar of aqua regia has been capped off now, and a variety of anodes, cathodes, and other working substances are suspended in it, held in place by clamps of hammered gold.

The fluorides react with the carbon anodes to form polyfluorocarbons, which are carcinogenic.

Overall, smelters using prebaked anodes are about 3% more energy efficient.
