A battery‚ which is actually an electric cell‚ is a device that produces electricity from a chemical reaction. In a one cell battery‚ you would find a negative electrode; an electrolyte‚ which conducts ions; a separator‚ also an ion conductor; and a positive electrode. Batteries are made of magnesium dioxide‚ graphite‚ electrolytes‚ zinc oxide and a paper soaked in an electrolyte solution. All of this is sealed in a insulated tube for safety. http://answers.ask.com/consumer_electronics/other/what_are_batteries_made_of
