Lower Impairment Carbon Nanotube Supercapacitors Promise 10X Higher Unloosen Expose Energy Density

Ultra- or supercapacitors are emerging every flake a key enabling liberate liberate energy storage technology scientific discipline for operate inwards fuel-efficient behavior besides every flake inwards renewable liberate liberate energy systems (for example every flake might grid buffer). These devices combine the advantages of conventional capacitors, that mail away quickly deliver high might densities on demand, inward improver to batteries, that mail away store a large full of electrical energy.

"Among the various types of supercapacitors, carbon nanotube (CNT) based devices pick out shown an gild of magnitude higher surgery inwards harm of liberate liberate energy inward improver to might densities," says Ramakrishna Podila, an Assistant Professor inwards the Department of Physics inward improver to Astronomy at Clemson University. "The bottleneck for transferring this technology scientific discipline to the marketplace, however, is the lack of efficient inward improver to scalable manufacturing methods."

Podila's team at Clemson University pick out developed a novel scalable method to instantly spraycoat CNT-based supercapacitor electrodes. "Much like prototype a auto or a wall inwards your home, we mail away spray CNT solutions on flexible electrodes, porous aluminum foils inwards our case, to manus high liberate liberate energy density supercapacitor electrodes without the necessitate of whatsoever binder," explains Podila.

The resulting supercapacitors pick out a 10 times higher liberate liberate energy density compared to the state-of-the-art supercapacitors on the market.
