How Batteries Work The pile or battery remained a laboratory curiosity for years, until the newly invented telegraph and telephone created a demand for reliable electrical power. After many years of experimentation, the "dry cell" battery was invented in the 1860s for use with the telegraph.

A battery has a positive and a negative electrode. The positive electrode is called a cathode, and the negative electrode ... To power a light, for example, the electrons go though a circuit, powers the light and arrives at the positive end (cathode) of the battery. (view diagram) ...
