Hemp versus lithium: electric cars could be operated more efficiently by hemp batteries in the future message


Hemp as a substitute for lithium

In the race against global warming and ongoing environmental pollution, sustainable energies in industry are becoming increasingly important. The auto industry has been experiencing an ever-increasing switch to electromobility for a number of years, which primarily requires powerful batteries. Most of these batteries are made from lithium. This is the heart of the electric car and is therefore also called “white gold”.

But research has identified another useful product that could form the basis of high-performance batteries in the future. Studies suggest that hemp batteries 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 YouTube channel, has shown that the value of the volt-ampere currents for the hemp battery was almost eight times greater than for the conventional lithium battery.

Smith does not claim to have proven anything by this, the experiment only shows how much more efficiently the hemp cell works 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 in the end are better than graphene capacitors, the study says from Dr. David Mitlin. In addition, hemp only costs a thousandth of what graphene costs.

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 carbon nanosheets.

These fibers are then processed into so-called supercapacitors, i.e. to store electricity. While conventional batteries have a large energy store and emit the energy drop by drop, this happens rapidly in one go with supercapacitors. Accordingly, the hemp batteries are ideal for machines that require strong energy impulses.

“[Die Carbonate] work at temperatures down to zero degrees Celsius and have one of the best documented power-power combinations for any carbonate, “Mitlin comments in the study.

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