Will hemp batteries be used in modern electric vehicles?

27.07.2020

Hemp batteries perform eight times better than lithium-ion batteries, and the production of graphene-like materials is worth a thousandth of what is currently used to make modern batteries, since it is actually based on recycling waste from the main hemp production.

On the pages of the specialized electronic edition of Ukrainian cannabis growers, the mechanisms of using various components of the hemp plant in the modern automotive industry have been described more than once. In particular, special attention was paid to biocomposite materials made on the basis of hemp, which have become widespread in modern car brands, produced both in Europe and in North America. On the one hand, there is a rapid transition of leading automotive corporations from the production of cars based on technologies involving the use of internal combustion engines to electric vehicles. On the other hand, we recall our publications about experiments aimed at studying the possibilities of using hemp in the production of modern batteries and a trivial question arises - "Can hemp batteries be used in the production of modern electric vehicles." For comments on the question raised by the editors about the possibility of using hemp fibers in the production of super-accumulators, as well as the possibility of using them in the production of electric vehicles, the editors turned to the specialists of the information and analytical platform Hemp Consulting. 

History

It's no secret that back in 1941, Henry Ford introduced the "Model T", the body of which was made using biocomposite materials based on hemp, and the tank of the car was filled with biofuel made from hemp plant derivatives. On this occasion, Popular Mechanics magazine published an article stating that the hemp car is "a step towards materializing the belief of Henry Ford that he will one day" grow "a car out of the soil."

Modernity

There is a trend in which electric vehicles have begun to displace combustion vehicles from the market. This is evidenced by the emergence of large automobile companies specializing in the production of electric vehicles, as well as the reorientation of international automobile corporations to the production of cars, which are based on the principles of obtaining energy from batteries. Huge resources are being invested in financing developments related to the creation of storage batteries of significant capacity, capable not only of giving an electric vehicle a range of several hundred kilometers, but also being charged within an extremely short period of time.

Technologies associated with the possibility of using hemp components in the production of batteries, which are planned to be massively used in modern electric vehicle construction, are rapidly developing. In 2014, US researchers discovered that hemp fiber could be turned into "ultra-fast" batteries that "perform better than graphene." A team of Dr. David Mitlin of Clarkson University, New York, has turned hemp stem derivatives into "carbon nanoribbons" with very encouraging results in experiments. Already at the end of 2019, researchers specializing in this kind of technology announced that hemp batteries could be more powerful than lithium and graphene used in conventional batteries. For example, hemp batteries perform eight times better than lithium-ion batteries, and the production of graphene-like materials is worth a thousandth of what is currently used to make modern batteries, since it is actually based on recycling waste from the main hemp production. This technology is called "hydrothermal synthesis". Researchers are currently trying to create a technology for converting hemp fibers into large capacitors. In the case of commercialization of this concept, hemp supercapacitors created on the basis of the hemp supercapacitors developed by American specialists will be able to change the paradigm of thinking regarding methods of storing energy, and can also be widely used not only in electric vehicles, but also in any other technology.

According to Mr. Mitlin, “You can make a battery from a dense block of carbon - we call it pseudo-graphite - and the technology itself is great for sodium ion batteries. But if you look at hemp fiber, its structure is the opposite, which allows you to create sheets with a large surface area, which is what is needed to create supercapacitors. "

The studies carried out indicate that hemp capacitors, in comparison with similar ones made of graphene, demonstrate not worse, but often better performance characteristics. Those. conducted studies of the effectiveness of using hemp batteries indicate the advisability of using this particular type of capacitors at least as the main batteries used in the rapidly developing electric vehicle industry.
