Etymology and History:

The word "anode" derives from the Greek "anodos," meaning "way up," combining "ana" (up) and "hodos" (way). It was first used in the 1830s by British scientists in electrochemistry. Over time, it evolved with advancements in battery technology, becoming standardized in global scientific lexicon. In Thai, it was adopted during the mid-20th century with the influx of Western education.

Literary References:

In H.G. Wells' "The World Set Free" (1914), the anode is mentioned in discussions of atomic energy: "The anode glowed with a fierce light as the electrons streamed from it." This highlights its role in early science fiction. In modern Thai literature, such as in science textbooks or articles by the National Science Museum of Thailand, "แอโนด" is referenced in educational passages to explain sustainable energy sources.
