As it turns out, used cigarette butts can be converted into material used for energy storage. South Korean scientists say this material could one day be used to coat the electrodes of supercapacitors which would enhance energy storage for things like electric cars, solar panels and wind turbines.
“Our study has shown that used cigarette filters can be transformed into a high performing carbon-based material using a simple one step process, which simultaneously offers a green solution for meeting the energy demands of society,” Professor Jongheop Yi of Seoul National University said in a statement.
