Hemp batteries could be 200 times cheaper to produce than conventional batteries.
North American researchers have developed hemp batteries used to power cars and tools.
As addressed in the CBD reports, researchers created batteries from cooked hemp pulp. They then processed it into carbon nanosheets. Result: Battery “equal to or better than graphene,” with is the battery industry standard.
The present invention is sustainable and economical because hemp pulp is not used in the textile and construction industries and often ends up in landfills.
Hemp pulp costs between $500 and $1,000 a ton, well below graphene’s price of about $200,000. If we extrapolate, the raw materials for this new energy model will be 200 to 400 times cheaper than conventional batteries.
The research was led by Dr. David Mitlin of Clarkson University (Potsdam, NY) spoke at the American Chemical Society meeting in San Francisco.
“We make a graphene-like material for a thousandth of the price, and we make it from scrap,” Mitlin said.
Unlike traditional capacitors, supercapacitors (called cannabis batteries) can quickly discharge their full charge. This makes them ideal for machines that rely on bursts of energy, such as regenerative braking in electric vehicles.
