$APHA $CGC $ACB Hemp batteries are coming, better than Graphene : By heating the hemp fibres for 24 hours at 350 degrees Fahrenheit, scientists were able to produce carbon nanosheets, which was then used to build supercapacitors. Fully assembled, the devices performed far better than commercial supercapacitors in both energy density and the range of temperatures over which they can work. The hemp-based devices yielded energy densities as high as 12 Watt-hours per kilogram, two to three times higher than commercial counterparts. They also operate over an impressive temperature range, from freezing to more than 200 degrees Fahrenheit. share-talk.com/batteries-ba...
