Hemp-Based Batteries Could Change the Way We Store Energy Forever!

As hemp makes a comeback in the U.S. after a decades-long ban on its cultivation, scientists are reporting that fibers from the plant can pack as much energy and power as graphene, long-touted as the model material for supercapacitors. They’re presenting their research, which a Canadian start-up company is working on scaling up, at the 248th National Meeting & Exposition of the American Chemical Society (ACS), the world’s largest scientific society.

Although hemp (cannabis sativa) and marijuana (cannabis sativa var. indica) come from a similar species of plant, they are very different and confusion has been caused by deliberate misinformation with far reaching effects on socioeconomics as well as on environmental matters.

Hemp is the most universally useful plant we have at our disposal. The history of mankind’s use of hemp can be traced way back in time to between about 5000 – 7000 BC.

Industrial hemp and hemp seed could transform the economy of the world States in a positive and beneficial way, and therefore should be exploited to its full potential, especially relating to energy storage.

David Mitlin, Ph.D., explains that supercapacitors are energy storage devices that have huge potential to transform the way future electronics are powered. Unlike today’s rechargeable batteries, which sip up energy over several hours, supercapacitors can charge and discharge within seconds. But they normally can’t store nearly as much energy as batteries, an important property known as energy density. One approach researchers are taking to boost supercapacitors’ energy density is to design better electrodes. Mitlin’s team has figured out how to make them from certain hemp fibers — and they can hold as much energy as the current top contender: graphene.

Really would love to see follow-on in that niche. It was first reported in 2014 and since has gone totally quiet despite hemp production having massively ramped up.

This is the first I’m hearing about this. They hold as much energy as graphene. Hemps ability to totally transform our entire society for the better is amazing. I’ll be looking for more information on this topic. Thanks for bringing it to my attention.
