Canadian and American researchers have developed batteries from hempused to power cars and tools.
As reported of Facts About CBD, the researchers built the batteries from cooked cannabis pulp. And then they processed it into carbon nanosheets. The result: batteries “equal to or better than graphene”, the industry gold standard.
Hemp Batteries: When someone’s junk becomes someone else’s treasure
Best of all, this invention is sustainable and economical since hemp pulp is not used for the textile and construction industries and therefore usually ends up in landfills.
Hemp pulp costs between $500 and $1,000 per ton, a price much lower than graphene, which costs around $200,000 per ton. If we extrapolate, the raw material for this new energy model would be 200 to 400 times cheaper than that of a classic battery.
The research was carried out by dr David Mitlinout Clarkson University (Potsdam, NYS) and presented during a meeting of American Chemical Society in San Francisco.
“We make graphene-like materials for a thousandth the price, and we make it with waste,” says Mitlin said.
Unlike traditional ones, supercapacitors (as hemp batteries are called) can quickly discharge their entire charge. This makes them ideal for machines that rely on bursts of energy, such as regenerative braking in electric cars.
