The use of silicon as anode material promises high theoretical energy density in lithium-ion batteries. However, the volume of a silicon-based anode may increase substantially during lithiation. In order to solve this problem, scientists at the Institute of Photovoltaics (ipv), University of Stuttgart, now succeeded in developing a method for producing micro-stabilized and porous silicon anodes by means of laser irradiation. The battery electrodes related to this invention offer a high potential for lithiation and at the same time improved mechanical stability. Due to a large active surface they provide high energy density. They can be used for the production of mechanically flexible batteries.

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.
The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".
Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
