Old Cigarette Butts Can Be Used as Material for Supercapacitors

The world has too many nasty old cigarette butts. On the other hand, the world could use some supercapacitors, the high-tech replacements for batteries that could potentially charge in seconds. Scientists in South Korea have found a simple process to turn used cigarette filters into high-performing material that works better than graphene or carbon nanotubes in supercapacitors.

These New Graphene Supercapacitors Could Finally Power An Electric Car

A team of South Korean scientists has developed a new graphene supercapacitor that can store almost as much energy as a lithium-ion battery, but charge in only 16 seconds. This makes it an ideal material to store braking energy and could be exactly what the electric car industry needs. Read More >>
