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 way back in history. Sometime between 640 B.C. C. and 250 a. C., the first known battery was created. These early batteries are known as “Baghdad Batteries” and we still know very little about them and why they were built. The Baghdad Batteries are tall terracotta jars fitted with a copper cylinder made up of a rolled copper sheet. Inside the copper you will find an iron rod that is insulated by plugs or plugs made of asphalt. If the jar is filled with liquid, the metal will be completely surrounded by liquid, and some historians believe that grape juice, lemon juice, vinegar, or similar acid solutions were used to start an electrochemical reaction in the jars.
In a nutshell: 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 electrolyte in the battery. This type of reaction is formally known as “faradaic reaction” and 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, lithium-containing cells sometimes put out 3 volts or even more, since their chemistry is so 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 well after 640 BC. In 1745, Ewald Jürgen Georg von Kleist built a form of capacitor that became known as “the Leyden jar.” 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 investigating the biological effects of electricity. The galvanic cell was capable of producing an electrical current far greater than the currents produced by earlier 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 their other ends were exposed to salt water. Today, galvanic cells are also known as voltaic cells and electrochemical cells.
In 1800, the Italian physicist Alessandro Volta built the voltaic pile. Volta understood how metal and chemicals can produce electric current when they come into contact with each other. He used copper and zinc discs (sometimes silver and 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 by his extensive research into the electric field. Another important experiment that took place in the year 1800 was carried out by William Nicholson and Anthony Carlisle. Nicholson and Carlisle succeeded in showing how a battery could be used to break down water into hydrogen and oxygen.
