Have you ever wondered how a battery works? I mean how do they the store electricity in a little tube? Plus it lasts for so many hours. Well in this paper I am going to answer all of those questions. In this paper I will tell you all about dry cells, wet cells, safety, and basic facts. I will get into further detail in these topics also.
Here are the basic facts of batteries. Batteries were said to be used by the "partisans" (a tribe in Iran). Alessandro Volta made the discovery of it in the 18th century. When he discovered it he named it a voltaic cell. The volt was named after him also. The types used today were discovered by George Le`lanche. .
There are currently 14 types of batteries in the world. The Zinc-Carbon cell is the most commonly used. The names of the batteries are: .
Fuel cell, Zinc-air cell, Lithium cell, Sodium cell, Mercury-Cadmium cell, Indium cell, bismuth cell, seawater cell, Magnesium cell, Percolate cell,.
alkaline, mercury cell, Silver-Cadmium cell Aluminum-air cell. Batteries range in sizes from some used in a watch as small as a fingernail, or some .

This is how you make a simple battery. To make a simple battery just fills up a cup with lemon juice (it acts as a acid). Take a plate of Zinc and a carbon rod. Connect them together with a metal wire. Put the zinc and carbon rod under the lemon juice. There should be a small flow of electricity flowing through the wire. You could try to use different metals instead of the zinc plate & carbon rod. For example you could use a sheet of tin foil and a nail, or a nickel and penny, etc. Keep in mind that only metal materials will work in this experiment.
A battery works by chemical energy changing into electrical energy. The battery contains special chemicals that change into other chemicals as it works.
