Discarded cigarette butts are a blight on city streets â but now one group of scientists has come up with a way to reuse them to save the environment. Researchers from South Korea believe they can convert cigarette filters into a material that could be used by computers, electrical vehicles and wind turbines to store energy. This material can be used to coat the electrodes of supercapacitors, which are components that can store extremely large amounts of electrical energy.
The following includes some materials that are known to conduct electricity: 1  metals: I know you specified nonmetals, but I wouldn't feel right not mentioning them anyway. 2  metalloids: They conduct electricity at high temperatures and/or voltages, but not under most normal conditions.
