The Chemistry Of Batteries People use batteries in their everyday life without thinking of their impact Batteries help us get around keep in touch have fun and tell the time They do this by powering our cars cell phones pagers portable CD players watches and many other useful tools They can even save our lives by powering things like smoke detectors carbon dioxide detectors and glucose meters In this term paper I will discuss how batteries function what types of batteries exist what gives them their power and many other topics related to batteries The battery also known as an electric cell is a device that converts the energy from chemicals into electricity Chemical reactions that are able to produce electrons are called Electro-chemical reactions A battery basically consists of two or more cells that are connected in a series or parallel All cells are made of a liquid paste or solid electrolyte and a positive electrode as well as a negative electrode The electrolyte works as an ionic conductor this causes one of the electrodes to react This reaction produces electrons while the other electrode accepts the electrons Every battery has two terminals one positive and the other negative Electrons collect on the negative terminal of the battery If the negative and positive terminal are connected together then connected to whatever device that needs to be powered also called a load the electrical current will flow freely into the device The speed of the electron production by the chemical reaction is called the batterys internal resistance This controls how many electrons can flow between the two terminals Because electrons must flow from the battery into a wire and then must travel from the negative to the positive terminals in order for the chemical reaction to take place This is why batteries can go unused for a year and still have plenty of power There are two general types of batteries Batteries that
