South Korea's R&D cigarette can be used as a super battery

South Korean scientists have made an exciting breakthrough by developing a method to turn cigarette butts into high-performance energy storage devices. These devices could potentially power smartphones, electric vehicles, and even household electronics.

Researchers from Seoul National University recently published their findings in the journal *Nanotechnology*, detailing how they transformed cigarette filters—commonly made of cellulose acetate—into advanced materials suitable for use in supercapacitors. This innovative approach not only addresses a major environmental issue but also opens up new possibilities for sustainable energy solutions.

The team explained that the process involves converting the filters into carbon-based materials, which are known for their excellent electrical conductivity and stability. They believe this method is both simple and cost-effective, making it a promising option for large-scale implementation.

Supercapacitors made from these materials offer significant advantages over traditional capacitors. They can store more energy, charge faster, and have a longer lifespan. According to the researchers, this technology could play a key role in meeting the growing demand for clean and efficient energy storage systems.

In addition to its environmental benefits, the project highlights the importance of recycling and repurposing waste materials. With millions of cigarette butts discarded every year, finding practical uses for them could help reduce pollution and promote a circular economy.

As reported by the American anti-smoking organization Americans for Nonsmokers’ Rights, cigarette butts are the most common form of litter worldwide, with over 765,000 tons generated annually. This new development offers a creative solution to a long-standing problem.
