New Graphene-based supercapacitor can store as much energy as a NiMH battery

Researchers from Nanotek Instruments have developed a new graphene-based supercapacitor that can store as much energy as NiMH batteries, but charge and discharge in minutes or
even seconds. The new device has a specific energy density of
85.6 Wh/kg at room temperature and 136 Wh/kg at 80 °C. These are the
highest ever values for "electric double layer" supercapacitors based on
carbon nanomaterials.

Welcome - about us

Welcome! Nanopaprika was cooked up by Hungarian chemistry PhD student in 2007. The main idea was to create something more personal than the other nano networks already on the Internet. Community is open to everyone from post-doctorial researchers and professors to students everywhere.

There is only one important assumption: you have to be interested in nano!

Nanopaprika is always looking for new partners, if you have any idea, contact me at

Dr. András Paszternák, founder of Nanopaprika
