This is How a Car Battery Works

It is an undisputed fact that a car cannot function without the car battery. The car battery generates the power required for starting the car. Additionally, other appliances of a car like the spark plugs, glow plugs, lights and electronic applications require energy provided by the car battery as well. 

So, along with the knowledge of the Exide or Amaron battery online price, it is essential to understand how a car battery works. For that, one needs to understand its structure and mechanism. 

1. Components and Structure of a Battery Cell

There are two elements in a battery cell. They are:

• Positive electrode: When talking about a lead-acid battery, it is important to know that it has a positively charged plate, called a positive plate, that consists of lead oxide immersed in an electrolyte. Also, there is a positive grid which consists of a lead alloy used to hold the active material.
• Negative electrode: The negatively charged plate, which is a part of this electrode, consists of pure lead immersed in an electrolyte. Similar to the positive grid, the negative grid serves the same purpose as well. 

2. Function of a Car Battery

The main function of a car battery is to store energy in chemical form and then convert it into electrical energy. This electrochemical process involves the reaction of four materials, namely hydrogen, oxygen, lead, and sulfur. The working of a car battery is explained in the following steps:

• The electrolyte, which is a mixture of sulfuric acid and distilled water, decomposes in positively charged hydrogen ions and negatively charged sulfate ones. When this happens, the electrons travel from the negative end to the positive one through the external consumer.
• To make up for the flow of these electrons, sulfate ions move from the electrolyte into the negative electrode and react with the lead, resulting in lead sulfate. 
• The same lead sulfate is produced in the positive electrode. Bonding of oxygen in the lead oxide is broken up with the help of transfer of electrons and then the oxygen passes through the electrolyte. In this scenario, the remaining lead reacts with the sulfate from the electrolyte. 
• When this happens, the oxygen bonds with hydrogen to create water, and as the sulfuric acid is used for the formation of lead sulfuric, the concentration reduces. Only when the concentration of sulfuric acid dips below a certain level, the battery needs to be recharged. 

So, the next time you are purchasing an Amaron or Exide car battery, you will be able to judge for yourself the technicalities and structure of the same.
