From Cigarette Butts to high performance battery

According to an estimate, about 5.6 million used cigarettes are littered away into the environment, causing environmental hazard. A South Korean, group of scientists have found a way to stop this. They not only stop this, but they are making good use of it.

They found that the cigarette butt that is mostly composed of cellulose acetate can easily be changed into a carbon-based material that out-performs common materials used in energy storage devices.  The researchers were able to do it by a simple burning technique called pyrolysis.

This material can be used to coat the electrodes in electronics like computers, smartphones, and even wind mills.
