History and mechanics of a Dry Cell Battery

Although batteries can be dated back to the Sumarian empire. See in 1938 Dr. Wilhelm Konig identified a jar that was most likely used as a battery. When replicas were filled with an acid these jars would produce between 1.5 to 2 volts each. This could be the earliest battery ever found on earth, because it dates back to 2500BCE. As should be noted, these batteries relied on acid as their electrolytic solution.

Well the earliest battery to modern man can be dated back to 1866. Its inventor was Georges Leclanché and it was termed the Leclanché cell. This rather rudimentary battery used an electrolyte of ammonium chloride, a cathode made of carbon, and what he termed as a depolarizer of manganese dioxide and an anode of zinc. This was the forerunner of today's dry cell batteries.

The chemical process which makes this cell function as a battery is started with the zinc anode which becomes oxidized, giving up their two electrons. After traveling through the circuit it is connected to the electrons combine with the manganese dioxide which is combined with water to produce manganese oxide. And thus the electrochemical process is completed.

The Leclanché cell saw extensive usage with the telegraph systems. And was virtually maintenance free. Be sure to subscribe to mt blog below to learn more green energy news.
