Can the crumbs of a cigarette alternative energy source?
The cigarette butts from cigarettes are almost like a plague on the streets of cities. But a group of scientists developed a way to put a stop to this source urban pollution and protect the environment.South Korean investigators believe they can convert the filters of cigarettes in a material that can be used by computers, electric vehicles and wind towers to store energy. According to scientists, the material of the cigarette filters can be used to coat the electrodes of the supercapacitadores, which are the components that can store large amounts of electricity.Scientists argue that cigarette filter performance is even better than the commercially available carbon, the carbon nanotubes or Graphene used currently. Every year, about 5.6 trillion cigarettes used, which amounts to 766,571 tonnes, are thrown into the streets."Our study demonstrates that the cigarette filters used may be transformed into a high-performance material carbon-based, using a single process, which at the same time offers a green solution to satisfy the energy needs of society," said Yi Jongheop, co-author of the study and a professor at the National University of Seoul, cite the Daily Mail.The supercapacitadores are composed primarily of carbon, due to their low cost, large surface area, good electrical conductivity and great stability. Around the world, scientists are studying ways to improve the characteristics of supercapacitadores, as the energy density, power density and stability of cycle, at the same time trying to reduce production costs.In the study, researchers found that Koreans cellulose acetate fibers from cigarette filters are made can be transformed into carbon-based material through a technique called pyrolysis combustion. The resulting material contains a considerable number of small pores, which increases its performance as a supercapacitador material.Foto:  Axolot / Creative Commons
