A team of researchers at the U.S. Department of Energy’s Argonne National Laboratory, discovered that nanotubes composed of titanium dioxide can switch their phase as a battery is cycled, gradually boosting their operational capacity. Laboratory tests showed that batteries produced with this material could be recharged up to half of their original capacity in less ... »
Lithium-ion batteries have found use in various portable devices, but their storage capacity limits the usability of those gadgets. As we mentioned in a couple of our previous articles, we need a new battery systems capable to charge faster and store more energy. Researchers from the Karlsruhe Institute of Technology (KIT) found a potential solution ... »
A multidisciplinary team of researchers from the Karlsruhe Institute of Technology (KIT) has been inspired by the way water is transported in trees and they used the same physicochemical effect to develop a faster way to fill the porous electrodes of lithium-ion batteries with liquid electrolyte. Aside lowering the time needed for battery consumption, the ... »
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 ... »
