Used cigarette butts offer energy storage solution

People are used to the fact that renewable energy sources are capable of providing us with what we need without a bad impact on our environment. Solar, wind, water power is an important part of our lives. It is also essential that we know how to keep the energy for the future use and still make it sustainable. Reflecting on the previous post about the Redox battery and energy storage solutions: scientists came up with the electrolyte cell to keep the energy flow at constant, but what are the other choices we have?

What if there are solutions that we might have not even thought about? Can the sustainable solutions come from something highly unsustainable?

Like the one that I've recently stumbled across - using cigarette butts for energy storage.

Everyone knows that the remains of the cigarettes - the filters are non-biodegradable and toxic.

This was always an issue of pollution and waste disposal. But now, South Korean scientist found out that the fibres inside the filters can be transformed by a simple act of burning into high-capacity material. According to the study, the end material has better performance than already available carbon and graphite. There is a possibility of extending its future use into storing extremely large amount of energy.
