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.


Lithium sulfur batteries: electrodes and prototype cells

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: Interfacial Superconductivity: Magnetic and superconducting order revealed simultaneously

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.

While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...

At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).

Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...
