The history of the AAA battery

The AAA battery is a small device capable of storing chemical energy. The modern AAA battery can actually trace its history far back in history. Sometime between 640 BC. C. and 250 a. C., the first known battery was created. These first batteries are known as “Baghdad batteries” and we still know very little about them and why they were built. Baghdad Batteries are tall terracotta jars fitted with a copper cylinder made of rolled copper foil. Inside the copper, you will find an iron rod that is insulated by plugs or plugs made of asphalt. If the flask is filled with liquid, the metal will be completely surrounded by liquid, and some historians believe that grape juice, lemon juice, vinegar, or similar acidic solutions were used to start an electrochemical reaction in the flasks.

Simply put: a battery consists of one or more voltaic cells. Chemical energy is transformed into electrical energy through chemical reactions that serve to transfer charge between the electrode and the battery electrolyte. This type of reaction is formally known as the “faradaic reaction” and it is what causes current to flow through the battery cells.

Most of the voltaic cells used in commonly available AAA batteries are 1.5 volt voltaic cells. However, cells containing lithium sometimes emit 3 volts or even more, since their chemistry is very different. Single cell rechargeable alkaline AAA batteries can be rated even lower than 1.5 volts; about 1.2 volts. Transistor-Transistor Logic (TTL) are 12 volt units and automobile electrical systems use 12 volts.

The modern development that eventually led to the construction of the AAA battery began long after 640 BC. In 1745, Ewald Jürgen Georg von Kleist built a form of condenser that became known as “the Leyden jug”. In 1748, Benjamin Franklin devoted himself to the study of electricity and began using the term “battery” for electronic storage devices. In 1786, Luigi Galvani discovered how to build a galvanic cell when he was researching the biological effects of electricity. The galvanic cell was capable of producing an electrical current much greater than the currents produced by previous chemical devices. However, the galvanic cell produced the electricity at a lower voltage. The first galvanic cell consisted of two different metals. The metal pieces were in contact with each other and at the same time had their other ends exposed to the salt water. Today, galvanic cells are also known as voltaic cells and electrochemical cells.

In 1800, the Italian physicist Alessandro Volta built the Voltaic stack. Volta understood how metal and chemicals can produce electrical current when they come into contact with each other. He used copper-zinc discs (sometimes silver-zinc discs) and separated them with a cloth soaked in salt water. In 1801, Alessandro Volta showed his discovery to Napoleon Bonaparte and was later ennobled for his extensive research within the electric field. Another important experiment that took place in the 1800s was that of William Nicholson and Anthony Carlisle. Nicholson and Carlisle were able to show how a battery could be used to break down water into hydrogen and oxygen.
