Meaning and history of the Term ‘’Battery’’ and its applications

The term battery refers to the composition of single or multiple cells where the electrons start a flow in a circuit by the chemical reaction of those cells. The batteries are composed of two main parts that act as anode, cathode and electrolytes.

The anode act as a negative side while cathode as the positive side. The electrolyte is a mixture that actually reacts chemically with the positive and negative side of the battery. A chemical reaction takes place once the positive and negative side is connected to a circuit.

During the reaction, the electrons start flowing through the circuit. The electron goes through the circuit into the cathode and a new chemical reaction is created.

A time reach when the material is all used during the reaction and then the battery could not perform further reaction and stops working. The battery if is a primary battery can be recharge is of no use in the future but if the battery is secondary type then we can recharge and use it for future projects.

 

History of the term ‘’Battery”:

 

The word battery was used for the things that joined together and perform the work in the past. The word was used for a series of capacitors by Benjamin Franklin in 1749 for the first time.  Then the term was a start to use commonly for every electrochemical cell.

 

How was battery invented?

 

An Italian physicist, a biologist and philosopher named Luigi Galvani performing the dissection of a frog which was held to a brass hook. The leg of frog twitched every time he touched it with an iron scapel. He thought that the energy comes from the frog’s leg.

Later his fellow, Alessandro Volta introduced that the frog’s leg stimulates were cause because of the medium.

 

Batteries and their applications:

There are many types of batteries that come under primary and secondary batteries. They are alkaline batteries, mercury batteries, silver-oxide batteries, Lithium battery, etc.

Following are some applications of different types of batteries:

  • Alkaline batteries are commonly used throughout the world especially in US, United Kingdom and Switzerland. They work for a long time which is mostly used in remote controls, clocks and radios etc. moreover they are also used in digital cameras etc.
  • Zinc Carbon batteries are very cost effective and are mostly used in electronic devices. They are commonly used in flashlights, toys etc.
  • The lead-acid battery is commonly used in lighting and other such systems. It has one other form which is wet cell battery and is used in computers and telephones exchange etc.
  • Mercury battery is used in photographic light meter and other such electronic devices.
