Batteries and Their Importance-
A detailed Summary of Batteries and Their Importance-
We use batteries everyday, we use them to start our cars and
to listen to our Walkmans. I have a few questions: How do batteries
work? What are the different kinds of batteries? Why do they die? Why
do they lose energy when they are not used for a long time? Well I
tried my best to find the best answers for these questions and a
Battery, also called an electric cell, is a device that
converts chemical energy into electricity. All batteries contain an
electrolyte, a positive electrode, and a negative electrode. There are
two general types of batteries. Batteries in which chemicals cannot be
reconstituted into their original form once their energy have been
converted these are called primary cells. Batteries in which the
chemicals can be reconstituted by passing an electric current through
them in the opposite direction are known as secondary cells, are
The primary battery is the most common type of battery used
today, invented by the French chemist Geoges Leclanche in the late
1860's. At the time this invention was very important and helped the
start of the industrial revolution. It allowed people with portable

terminal and a negative charge on the negative terminal, month after
also. The coat of lead sulfate makes the battery less efficient. When

Both plates are immersed in a solution of sulfuric acid, this acts as
rubber, or plastic, called separators. All the positive plates are
