“Popcorn” particle pathways promise better lithium-ion batteries
06/11/2013 - 09:32

Researchers at Sandia National Laboratories have confirmed the particle-by-particle mechanism by which lithium ions move in and out of electrodes made of lithium iron phosphate (LiFePO4, or LFP), findings that could lead to better performance in lithium-ion batteries in electric vehicles, medical equipment and aircraft.

Quantum State of a Single Atomic Nucleus Can Be Controlled and Determined by Simple Electrodes
08/16/2012 - 07:18

Quantum computers promise to reach computation speeds far beyond that of today’s computers. As they would use quantum effects, however, they would also be susceptible to external interferences. Information flow into and out of the system is a critical point. Researchers from KIT with partners from Grenoble and Strasbourg have now read out the quantum state of an atom directly by using electrodes. In the Nature journal, it is reported about the stable interface between classical and quantum world.

UCLA team develops highly efficient method for creating flexible, transparent electrodes
11/21/2011 - 17:24
As the market for liquid crystal displays and other electronics continues to drive up the price of indium — the material used to make the indium tin oxide (ITO) transparent electrodes in these devices — scientists have been searching for a less costly and more dynamic alternative, particularly for use in future flexible electronics.

New understanding of high-performing cathode compound could facilitate rapid evaluation of improved alternatives
08/12/2011 - 10:20

Lithium-ion batteries have become a leading energy source for everything from smartphones and laptops to power tools and electric cars, and researchers around the world are actively seeking ways to nudge their performance toward ever-higher levels. Now, a new analysis by researchers at MIT and the University of California at Los Angeles (UCLA) has revealed why one widely used compound works particularly well as the material for one of these batteries’ two electrodes — an understanding they say could greatly facilitate the process of searching for even better materials.
