Scientists at the Naval Research Laboratory (NRL) Materials Science and Technology Division are developing novel, lightweight energy storage devices. Rather than depend on highly acidic electrolytes, ionic liquids are used to create a solid polymer electrolyte composed of an ionic liquid and polyvinyl alcohol, thus developing novel types of solid state batteries with discharge voltages… »
A group of researchers from University of Illinois developed a three-dimensional nanostructure for battery cathodes that allows dramatically faster charging and discharging without sacrificing energy storage capacity. Aside from quick-charge consumer electronics, batteries that can store a lot of energy, release it fast and recharge quickly are desirable for electric vehicles, medical devices, lasers and… »
In our previous articles, we sporadically mention the need for breakthroughs in energy storing technology and the folks from the University of Illinois have developed a form of ultra-low-power digital memory that is faster and uses 100 times less energy than a similar memory available today. The technology could give future portable devices much longer… »
Battery developers know that recharging and using lithium batteries over and over damages the electrode materials. Researchers at the DOE’s Environmental Molecular Sciences Lab on the Pacific Northwest National Lab (PNNL) grounds have been observing how nanowires composed of tin oxide rapidly change shape and deform when they are being charged. “Nanowires of tin oxide… »
The Indian government unveiled the world’s cheapest “laptop” computer meant for students – a touch-screen device that costs $35. Developed by researchers at the Indian Institute of Technology and Indian Institute of Science, mass production of the computer might begin as soon as next year, claims Human Resource Development Minister Kapil Sibal, adding the government… »
When we write about gadgets and technology, we often mention the need for breakthroughs in energy storing technology. By using super-high pressures similar to those closer to the Earth core or on a giant planet, the researchers from Washington State University have created a compact, never-before-seen material capable of storing vast amounts of energy. “If… »
Stanford scientists are harnessing nanotechnology to quickly produce ultra-lightweight, bendable batteries and supercapacitors in the form of everyday paper. The research team led by Yi Cui, assistant professor of materials science and engineering, includes postdoctoral scholars Liangbing Hu and JangWook Choi, and graduate student Yuan Yang. Simply coating a sheet of paper with ink made… »
