Hemp fibres 'better than graphene' [View all]
http://www.bbc.com/news/science-environment-28770876
The waste fibres from hemp crops can be transformed into high-performance energy storage devices, scientists say.
They "cooked" cannabis bark into carbon nanosheets and built supercapacitors "on a par with or better than graphene" - the industry gold standard.
Electric cars and power tools could harness this hemp technology, the US researchers say.
They presented their work at the American Chemical Society meeting in San Francisco.
