The future of electric cars: are hemp batteries stronger than lithium?

Lithium-ion batteries have become indispensable in today’s society, they power mobile devices such as smartphones, tablets and laptops, but above all electric cars. However, research has shown that hemp batteries could be a more efficient alternative.

Hemp as a substitute for lithium

In the race against global warming and ongoing environmental pollution, sustainable energies are becoming increasingly important in industry. For several years now, the automotive industry has been experiencing an ever-increasing switch to electromobility, which requires high-performance batteries in particular. These batteries are mostly made from lithium. This represents the heart of the electric car and is therefore also known as the “white Gold” designated.

But research has identified another utility that could form the basis of high-performance batteries in the future. Studies suggest that batteries made from hemp are even more powerful than lithium and graphene batteries.

Hemp is a very versatile raw material that can be used in industry, for clothing and food and now also for batteries in electric cars.

More efficient and sustainable

An experiment by Robert Murray Smith, a scientist known for his YouTubechannel has shown that the value of the volt-ampere currents in the hemp battery was almost eight times greater than that in the conventional lithium battery.

Smith doesn’t claim to have proved anything, the experiment just shows how much more efficient the hemp cell is compared to the lithium cell, he explains in his video “Hemp Battery As Good As Lithium Ion?”.

However, this finding is nothing new, as early as 2014 researchers at Clarkson University in the US state of New York found that hemp waste products can be transformed into extremely efficient capacitors, which are ultimately better than graphene capacitors, according to the study from Dr. David Mitlin. In addition, the hemp costs only one-thousandth of what graphene costs.

Motorcycle manufacturer starts developing the battery

In the course of the experiment, the research group led by Dr. Mitlin leftover bast fibers, i.e. the inner bark of the hemp plant. The process is called hydrothermal synthesis and in this case resulted in nanosheets of carbon.

These fibers are then processed into so-called supercapacitors, i.e. into electricity storage devices. While conventional batteries store a large amount of energy and release the energy drop by drop, with supercapacitors this happens rapidly in one fell swoop. Accordingly, the hemp batteries are ideal for machines that require strong energy pulses.

“[Die Carbonate] function at temperatures as low as zero degrees Celsius and have one of the best documented performance-power combinations for any carbonate,” Mitlin comments in the study.

In 2018, Texas motorcycle manufacturer Alternet joined Mitlin’s research to develop hemp-based batteries for the ReVolt series of electric motorcycles. However, further development processes are required before hemp batteries become a mass product and a legitimate lithium substitute.
