How do Batteries Work
Invention of the battery is one of the biggest innovations of the 19th century. Batteries became chief source of power for both commercial and industrial use, after very few years of its invention. Now, it is also one of the chief sources of power and getting used by people through out the world.
Before going ahead to discuss the working method of the batteries, we should discuss about the different types of batteries available in contemporary world. The batteries available in today’s world can be divided into two categories and those are disposable batteries and rechargeable batteries. Now let us discuss about how these batteries work.
In case of a dry cell battery, there is a carbon rod in the middle of it, which serves as the cathode or the positive pole. On the other hand, at the base it has a zinc pot, which serves as the anode or the negative pole. The paste of ammonium chloride is placed through out the body of the dry cell and the whole cell is capsulated in a aluminum foil. Zinc chloride replaces ammonium chloride, in case of the high power dry cell batteries. When the negative end of a dry cell gets connected with the positive end of the cell, with the help of any outer wire, the electron flows from the electron rich negative end to the electron deficient positive end and the flow of electron sets up the current in the outer wire.
The dry cell batteries generally comes with a capacity of 1.5 V. However, more powerful dry cell batteries are getting produced, though their utility is limited. In fact, dry cell batteries are most used form of batteries, as it can power any device and that to under any circumstances.
Now let us discuss about the wet cell batteries. In case of the dry cell batteries, the electrolyte is in a paste form; however, in case of the wet cell batteries, the electrolyte is in the wet form or liquid form. The liquid electrolyte along with the anode and the cathode is arrested inside a non-conducting box. Both the positive and negative ends come out of the cover. When the positive end gets connected with the negative one with the help of any conducting wire, the electrons start flowing and the electric field sets up. Most rechargeable batteries are wet cell batteries. Wet cell batteries generally goes longer than the dry cell batteries.
As the technology advances, the batteries are getting the improvement. Now, batteries are coming in hundreds of different verities. We are going to see few more verities in the coming future.
