Are Hemp Batteries the Future for Electric Vehicles?

All that is needed to form the thin sheets of substrates that line the inside of a supercapacitor are the waste fibers from the hemp crop. The bark of the hemp plant gets converted into carbon nanosheets. Supercapacitors made from hemp work as effectively as industry-standard graphene material. To make it even better, it is environmentally friendly. Hemp bark normally ends up in landfills. But under the innovative eye of Dr. David Mitlin of Clarkson University, New York, the inner bark of the plant was cooked up and turned into carbon nanosheets. This process is called hydrothermal synthesis. By using waste material, graphene-like material is created for the fraction of the traditional amount needed. Hemp material is excellent for making large sheets with a high surface area. It is also stronger than diamonds and more conductive than copper.
