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\u2019re 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).<\/p>\n

David Mitlin, Ph.D., explains that supercapacitors<\/a> are energy storage devices that have huge potential to transform the way future electronics are powered. Unlike today\u2019s rechargeable batteries, which sip up energy over several hours, supercapacitors can charge and discharge within seconds. But they normally can\u2019t store nearly as much energy as batteries, an important property known as energy density. One approach researchers are taking to boost supercapacitors\u2019 energy density is to design better electrodes. Mitlin\u2019s team has figured out how to make them from certain hemp<\/a> fibers\u2014and they can hold as much energy as the current top contender: graphene.<\/p>\n

\u201cOur device\u2019s electrochemical performance is on par with or better than graphene-based devices,\u201d Mitlin says. \u201cThe key advantage is that our electrodes are made from biowaste using a simple process, and therefore, are much cheaper than graphene.\u201d<\/p>\n
