Report details how researchers used hemp
A report by Return to Now explains how the team cooked the woody pulp and made carbon nanosheets out of it. They then used the nanosheets to make supercapacitors. These were just as good or even better than the widely used graphene.
Supercapacitors are for energy storage. While they are commonly in the form of batteries, scientists have had challenges in developing capacitors that are on par with the rate of electronic component evolution.
High Grade Hemp Seed refers to help batteries as supercapacitors. It explains that Lithium-ion batteries can store energy for long periods and release it slowly. However, they cannot release energy quickly. Supercapacitors like hemp batteries can.
Supercapacitors can release all their energy quickly to boost a vehicle essential for an electric car. Despite this, they can’t store energy for a long time. Fortunately, they get preventative energy from braking.
Benefits of a hemp-based battery
According to Dr. David Mitlin, a lead study author and chemical engineer from Clarkson University, New York, using hemp instead of lithium batteries would make EVs and other devices sustainable. In addition, lithium-ion, which most car manufacturers use to make car batteries, is more expensive than hemp.
Hemp-based batteries hold many other benefits. These include it being cheaper than graphene. Hemp is cheaper to source than graphene as experts could use help waste derive from farmers. Furthermore, hemp only requires a few months to reach maturity and can grow in various soil types. Graphene, on the other hand, is hard to produce in large amounts.
