“We’ve pretty much figured out the
secret sauce of it,” says Mitlin, who’s now with Clarkson University in
New York. “The trick is to really understand the structure of a starter
material and to tune how it’s processed to give you what would
rightfully be called amazing properties.” His
team found that if they heated the fibers for 24 hours at a little over
350 degrees Fahrenheit, and then blasted the resulting material with
more intense heat, it would exfoliate into carbon nanosheets.Mitlin’s
team built their supercapacitors using the hemp-derived carbons as
electrodes and an ionic liquid as the electrolyte. 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.
“We’re
past the proof-of-principle stage for the fully functional
supercapacitor,” he says. “Now we’re gearing up for small-scale
manufacturing.”
