A Tohoku University research team has developed new materials for supercapacitors with higher voltage and better stability than other materials. Supercapacitors are rechargeable energy storage devices with a broad range of applications, from machinery to smart meters. They offer many advantages over batteries, including faster charging and longer lifespans, but they are not so good […]

Elsevier is reporting that a team of researchers from the Plasma Physics Research Centre, Science and Research Branch of Islamic Azad University in Tehran, Iran, have discovered a way of making paper supercapacitors for electricity storage. At one sheet thick, these new supercapacitors can bend, fold, flex, and still hold electricity. The team’s research paper […]

Georgia Institute of Technology researchers have developed a paper-based flexible supercapacitor using a simple layer-by-layer coating technique that could be used to help power wearable devices. The device uses metallic nanoparticles to coat cellulose fibers in the paper, creating supercapacitor electrodes with high energy and power densities – and the best performance so far in […]

Michigan Technological University researchers have developed a new way to make surface-microporous 3-D graphene, which has a unique structure of mesopores and micropores, that could be made into a supercapacitor. The new process makes tiny dents in the surface of the graphene greatly enhancing its potential as a supercapacitor. Even better, it can be made […]

Chinese scientists have introduced an extraordinarily stretchable and compressible polyelectrolyte. The new electrolyte when combined with carbon nanotube composite paper electrodes, forms a supercapacitor that can be stretched to 1000 percent in length and compressed to 50 percent in thickness without gaining and not losing capacity. The potential for flexible, wearable electronics that require equally […]
