Batteries
Introduction
Batteries are major part of everyday life all over the world. Without them, we would not be able to live life as we know it. They give us the lightweight, portable energy to run the devices we need in our everyday lives. The problem with batteries being such a big part of our lives is that the average person does not consider the environmental hazards. We use them until they don't work anymore and then throw them in the garbage without a second thought. It is hard to believe that something so essential could also be so dangerous to the environment.
Batteries work by converting chemical energy into electrical energy. Every battery has a positive end called an anode and a negative end called a cathode. Electrons collect on the negative end of the battery and flow through whatever you attach by wire on their way back to the positive side of the battery. The electrical current through the battery is caused by the voltage difference between the anode......
