Latest news around battery research

05.09.2016

Emerging markets for mobile energy storage currently boost the interest in next generation batteries. The Fraunhofer IWS will present the latest results at the 5th “Lithium-Sulfur Battery Workshop” on November 21 - 22, 2016 in Dresden. Renowned national and international experts from industry and science will come together to gain profound insight in the current and future trends and developments.

Holger Althues, coordinator of the IWS Battery Center and project manager of several related research projects comments on the recent status of the Li-S-technology: “Lithium-sulfur batteries are still the most promising innovation for future energy storage devices.

They offer the potential to significantly reduce the weight and decrease the costs when compared to Li-Ion-batteries. The major challenge, however, is to improve the lifespan of lithium-sulfur batteries.

Key to achieve this is to stabilize the electrolyte and lithium anode interface through material innovations. New electrolytes or protective films have to be discussed and evaluated as potential solutions.

Recently, IWS scientists have introduced a new electrolyte composition with drastic effect on the cathode and anode chemistry. This approach allows to reduce the volume of electrolyte in the system in order to increase the volumetric and gravimetric energy density on cell level.

Anode corrosion, the main reason for cell failure, is much less severe and the electrolyte‘s low flammability is an additional safety advantage. First results on prototype cells will be presented during this year’s Lithium-Sulfur-Workshop.

Im Focus: The largest genome ever: Decoding the Axolotl

A team of researchers led by scientists in Vienna, Dresden and Heidelberg has decoded the entire genetic information of the Mexican salamander axolotl. The axolotl genome, which is the largest genome ever to be sequenced, will be a powerful tool to study the molecular basis for re-growing limbs and other forms of regeneration. The journal NATURE publishes the news online on 24 January.

Salamanders have long served as valuable biological models for developmental, regeneration and evolutionary studies. In particular, the Mexican axolotl...

Im Focus: Optical Nanoscope Allows Imaging of Quantum Dots

Physicists have developed a technique based on optical microscopy that can be used to create images of atoms on the nanoscale. In particular, the new method allows the imaging of quantum dots in a semiconductor chip. Together with colleagues from the University of Bochum, scientists from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute reported the findings in the journal Nature Photonics.

Microscopes allow us to see structures that are otherwise invisible to the human eye. However, conventional optical microscopes cannot be used to image...

Im Focus: Artificial agent designs quantum experiments

On the way to an intelligent laboratory, physicists from Innsbruck and Vienna present an artificial agent that autonomously designs quantum experiments. In initial experiments, the system has independently (re)discovered experimental techniques that are nowadays standard in modern quantum optical laboratories. This shows how machines could play a more creative role in research in the future.

We carry smartphones in our pockets, the streets are dotted with semi-autonomous cars, but in the research laboratory experiments are still being designed by...

Im Focus: The first precise measurement of a single molecule's effective charge

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.

Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...
