A group of researchers from South Korea managed to convert used cigarette filters in high performance carbon material that can be embedded in computers, hand-held gadgets, electric vehicles and even wind turbines for energy storage.
In an article published in the journal Nanotechnology, researchers have shown that the possibilities of new material superior to commercially available graphene and carbon nanotubes.
This material is expected to be used for coating electrodes of supercapacitors – electrochemical elements capable of storing extremely large volumes of energy – as well as to solve a continuously growing environmental problem, which is used cigarette filters. By According to scientists, is thrown into the environment around the world 5.6 trillion, or 766.571 metric tons of cigarette butts each year.
Carbon is the most popular material for supercapacitors, due to its low cost, large area surface, high conductivity and long-term stability. Thanks to new technology, acetate fibers cellulose, of which mainly cigarette filters can be transformed into carbon material using simple one-step pyrolysis.
