A group of researchers hailing from Nanyang Technological University in Singapore have devised stretchable silver electrodes whose conductivity can be enhanced by human sweat. The stretchable electrodes were fabricated by directly printing an ink composed of conductive silver flakes and specially designed elastic binder called hydrophilic poly(urethane-acrylate) (HPUA) on hydrophilic textiles. Researchers say the HPUA…

Researchers from the University of Münster in Germany looked at 53 studies that estimated advances in lithium-ion, solid-state, lithium–sulfur and lithium–air batteries. Their conclusion: Study authors generally expect continuously declining battery costs regardless of raw material price developments. But there are large cost uncertainties that will remain a key challenge for researchers and industry in…

by Empa, Swiss Federal Laboratories for Materials Science and Technology The fabrication device for the battery revolution looks quite inconspicuous: It is a modified, commercially available 3D printer, located in a room in the Empa laboratory building. But the real innovation lies within the recipe for the gelatinous inks this printer can dispense onto a…

A team of researchers led by chemists at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory has identified new details of the reaction mechanism that takes place in batteries with lithium metal anodes. The findings, published today in Nature Nanotechnology, are a major step towards developing smaller, lighter and less expensive batteries for electric…

Next time you find yourself swimming around with electric eels, try grabbing one and then put the leads of a battery powered oscilloscope on its head and tail. According to University of Central Florida zoology professor Will Crampton, you’ll probably measure a voltage in the 700-V range. Crampton and his associates went to the rivers […]

Engineers strive to design smartphones with longer-lasting batteries, electric vehicles that can drive for hundreds of miles on a single charge, and a reliable power grid that can store renewable energy for future use. Each of these technologies is within reach — that is, if scientists can build better cathode materials. To date, the typical…

By improving a water-in-salt battery prototype, researchers believe they are well on their way to developing new high energy batteries. A team from the University of Maryland (UMD) and the U.S. Army Research Lab (ARL) have created a new type of chemical transformation of the cathode that yields, for the first time ever, a reversible…

A trio of researchers with the University of Wollongong, in Australia, has published an outline of the current state of potassium-ion battery technology. In their Review piece published in the journal Science Advances, Wenchao Zhang, Yajie Liu, and Zaiping Guo highlight the current roadblocks that are preventing widespread use of the battery technology and possible workarounds…

QUT researchers will lead key research projects in expanding Australia’s battery industry from mining to manufacturing, with the announcement of the Future Battery Industries Cooperative Research Centre. The Future Battery Industries CRC will involve 58 industry, government and research partners, and has the backing of a $25 million grant from the Federal Government and more than […]
