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: Entangling photons from a quantum dot in the telecom C-band

A research team of the institute of semiconductor optics and functional interfaces (IHFG) of the University of Stuttgart experimentally verified the generation of polarization-entangled photon pairs in the emission wavelength range of the telecom C-band. The generation of entangled photons, i.e. a non-classical phenomenon which “bounds” the states of two different entities, is a cornerstone for the realization of quantum networks.

Quantum dots are one of the most prominent and promising candidates as non-classical light sources applied in quantum information technology. They have been...

By changing the wavelengths of entangled photons to those used in telecommunications, researchers see quantum technology take a major leap forward

The potential for photon entanglement in quantum computing and communications has been known for decades. One of the issues impeding its immediate application...

Im Focus: The fastest light-driven current source

Controlling electronic current is essential to modern electronics, as data and signals are transferred by streams of electrons which are controlled at high speed. Demands on transmission speeds are also increasing as technology develops. Scientists from the Chair of Laser Physics and the Chair of Applied Physics at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) have succeeded in switching on a current with a desired direction in graphene using a single laser pulse within a femtosecond ¬¬ – a femtosecond corresponds to the millionth part of a billionth of a second. This is more than a thousand times faster compared to the most efficient transistors today.

Graphene is up to the job
