Scientists turn cigarette butts into super batteries

Scientists in South Korea say they have found a way to convert used cigarette butts into high performance batteries called supercapacitors.

In a study published on Aug 5 in the journal Nanotechnology, researchers from Seoul National University outline how they managed to transform used cigarette filters, which are composed mainly of cellulose acetate fibres tainted with toxins, into a material that can potentially change the future of batteries.
