Crumpled graphene sheets for supercapacitors

As we know, one of the attractive features of graphene is it's large surface area and therefore its attractiveness for supercapacitors where energy is stored electrostatically rather than chemically. If you can increase this surface even more that should be beneficial and by "crumpling" the sheets you can as MIT have found. The graphene sheets are "crumpled by machine, being stretched in...

More on graphene and supercapacitors

Another group of US (Californian) scientists have been working on the use of graphene and CNT's to develop more efficient supercapacitors for energy storage (see article entitled Graphene and CNT Hybrid Supercapacitor ) They have deposited graphene on a nanoscale carbon nanotube porous foam that provides the high surface area that the electrolyte infiltrates. The foam is formed from a...
