There are too many dirty cigarettes in the world. And there are also some supercapacitors in the world that can replace batteries and use this high technology to complete charging in seconds. This totally irrelevant two things are now in touch. Scientists in South Korea discovered that through a simple process, used cigarette filters can be made into high-performance materials, so that working supercapacitors will have better results than graphene and carbon nanotubes.

Capacitors store energy in the form of electric charges, while batteries store chemical energy in the form of electricity. This means that supercapacitors are much faster than batteries during charging and discharging. But there isn't a lightning-fast supercapacitor in your laptop because of their size. At present, they are basically used for industrial production, such as storing the energy generated by wind turbines. Scientists are always looking for new ways to make better supercapacitors.
Cigarettes are an unexpected source of material. Cigarette filters are used in the manufacture of new supercapacitors and are currently rare, but they are widely present in sidewalks and park waste bins. This study was published in the magazine "Nanotechnology". Korean scientists explained how to handle cigarette filters to help supercapacitor manufacturing.
The material in the cigarette filter is a synthetic fiber known as cellulose acetate. When it is heated under nitrogen, the filter will become a perforated carbon-based material. This kind of pore structure helps to increase the surface area of ​​the material and make it have a better effect on the supercapacitor. The research team tested the material itself and the charge-discharge process and found that it was better than the materials sold on the market. Perhaps in the near future, such cigarette butts that are seen everywhere on the streets will be better recycled.
