Lithium-ion Batteries: Improvement with Nanoscale Research

Collaboration between UC San Diego and the National Labs could lead to new battery architectures New research led by an electrical engineer at the University of California, San Diego is aimed at improving lithium-ion batteries through possible new electrode architectures with precise nano-scale designs. The researchers created nanowires that block diffusion of lithium (Li) across their silicon surface and promote layer-by-layer axial lithiation of the nanowire’s germanium core. Shadi Dayeh, a professor in the Department of Electrical and Computer Engineering…

Wagon-wheel Rotelle Shape Make Better LEDs

‘Rotelle’ molecules depolarize light for LEDs; more efficient than ‘spaghetti’ One problem in developing more efficient organic LED light bulbs and displays for TVs and phones is that much of the light is polarized in one direction and thus trapped within the light-emitting diode, or LED. University of Utah physicists believe they have solved the problem by creating a new organic molecule that is shaped like rotelle – wagon-wheel pasta – rather than spaghetti. The rotelle-shaped molecule – known as…
