Turn the cigarette filter into a phone battery

New Korean scientists say they have found a way to turn cigarette filter heads into a series of energy-storing materials used for all devices from mobile phones to cars. electricity.

Each year more than 700 thousand tons of waste from filters, cigarette butts are put into the environment.

The results of this study are published by researchers from Seoul National University in the Journal of Nano Technology (the journal Nanatechnology) on August 5, 2014.

Accordingly, cellulose acetate fibers contained in discarded cigarette filters, which are considered hazardous and dangerous in the environment, will be converted into carbon materials that can be used in supercapacitor manufacturing, a type of device. It is allowed to store better power, faster charging and longer life than existing electrical devices.

Not only that, the team also said that carbon materials from cigarette filters will have low cost, high porosity, good electrical conductivity and stability.

This is also a very good way to protect the environment because according to a statistic of the anti-smoking advocacy group in the US, filters and cigarette butts every year are thrown away around the world, estimated at 765,000 tons of waste. .
