    Storing fluctuating and delivering stable electric power supply are central issues when using energy from solar plants or wind power stations. Here, efficient and flexible energy storage systems need to accommodate for fluctuations in energy gain. Scientists from the Leibniz Institute for Interactive Materials (DWI), RWTH Aachen University and Hanyang University in Seoul now significantly improved a key component for the development of new energy storage systems.

  • Applications of Graphene

    Application of Graphene

    In order to get introduced to Graphene, a good point of start would be Graphite. Graphite is a naturally-occurring form of crystalline carbon. It is a native element mineral found in metamorphic and igneous rocks. Regarding its composition, Graphite is a stack of carbon-atom layers.

  • Beim Laden von Lithium-Luft-Akkus entsteht hochreaktiver Singulett-Sauerstoff

    Lithium-Luft-Akkus gelten als Zukunftstechnologie: Theoretisch können sie nicht nur wesentlich leistungsfähiger sein als die derzeit gängigen Lithium-Ionen-Akkus, sondern auch leichter. Noch sind die neuen Energiespeicher allerdings nicht reif für die Praxis – schon nach wenigen Ladezyklen machen die Akkus schlapp. Woran das liegt, haben jetzt Wissenschaftler der Technischen Universität München (TUM) und des Forschungszentrums Jülich untersucht und einen potenziellen Übeltäter entdeckt: Hochreaktiven Singulett-Sauerstoff, der beim Laden des Akkus frei wird.

  • Electric mobility: Opportunities for climate protection in Europe

    Several Smart electric drive cars charging at the Potsdamer Platz in Berlin.

    Getting more electric vehicles on the roads in Europe can significantly reduce CO2 emissions and air pollutants within the European Union. If the share of electric mobility in passenger road transport increases to 80 percent by 2050, the CO2 emissions of the passenger road transport sector in Europe can be reduced by up to 84 percent compared to 2010.

    Researcher at TU Graz demonstrates in Nature Materials that it is possible to combine the high-energy density of batteries with the high-power output of super capacitors in a single system – thanks to liquid energy storage materials. Batteries and super capacitors are electrochemical energy storage media, but they are as different as night and day. Both are capable of energy storage and targeted energy release – and yet there are major differences between the two. Batteries store very large amounts of energy that is released slowly but constantly. By contrast, super capacitors can only store small amounts of energy, but they release this energy much faster and more powerfully with large short-term peak currents.

    For years, small rechargeable lithium-ion batteries have reliably supplied billions of portable devices with energy. But manufacturers of high-energy applications such as electric cars and power storage systems seek for new electrode materials and electrolytes. Michael Metzger, researcher at the Technical University of Munich (TUM), has now developed a new battery test cell allowing to investigate anionic and cationic reactions separately. Recently the researcher was honored with the Evonik Research Prize for his work.

  • Fraunhofer ISE Develops Highly Compact, High Frequency DC/DC Converter for Aviation

    The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.

    The Fraunhofer IWS has made another important step forward with respect to the research on n-conductive polymers for printed electronics. The Dresden scientists succeeded in modifying an n-conductive polymer, already synthesized in 2015, in such a way that it can now be processed as a paste and be printed in a three-dimensional manner.

    New Technique Removes Quasiparticles from Superconducting Quantum Circuits - An international team of scientists has succeeded in making further improvements to the lifetime of superconducting quantum circuits. An important prerequisite for the realization of high-performance quantum computers is that the stored data should remain intact for as long as possible. The researchers, including Jülich physicist Dr. Gianluigi Catelani, have developed and tested a technique that removes unpaired electrons from the circuits. These are known to shorten the qubit lifetime (to be published online by the journal Science today.

    Environmental energy provides an efficient way to supply energy to non-residential buildings such as office and administration buildings, educational and recreational facilities as well as industrial sheds. The buildings can be efficiently heated and cooled using the combined use of thermo-active building systems and heat pumps. Across 24 pages, the new BINE-Themeninfo brochure entitled "Efficiently heating & cooling non-residential buildings" (II/2016) presents low-exergy concepts for these buildings.

    Research into plant cells is far from complete. Scientists under the biochemist Professor Peter Dörmann at Universität Bonn have now succeeded in describing the function of chloroplasts in more detail. These are plant and algal cell structures that are responsible for photosynthesis. The results have now been published in the scientific journal "Proceedings of the National Academy of Sciences of the USA" (PNAS).

    Lithium Ionen Akkus Kapazität kann um das Sechsfache gesteigert werden | Lithium-Ionen wandern in die Schicht aus kristallinem Silizium ein. Im Lauf der Beladung bildet sich eine 20 Nanometer dünne Schicht (rot) in der Si-Elektrode, die extrem viele Lithium-Atome aufnimmt Abbildung: HZB

    Lithium-Ionen-Akkus könnten ihre Kapazität um das Sechsfache erhöhen, wenn ihre Anode statt aus Graphit aus Silizium bestünde. Ein Team vom Institut für weiche Materie und funktionale Materialien des Helmholtz-Zentrum Berlin (HZB) hat erstmals detailliert beobachtet, wie Lithium-Ionen in Silizium einwandern. Ihre Arbeit zeigt, dass schon extrem dünne Silizium-Schichten ausreichen, um die theoretisch mögliche Kapazität des Akkus zu realisieren. Die Arbeit ist veröffentlicht in der Zeitschrift ACSnano der American Chemical Socity (DOI: 10.1021/acsnano.6b02032)

  • Matter-antimatter symmetry confirmed with precision record

    CERN experiment sets precision record in the measurement of the antiproton to electron mass ratio using a new innovative cooling technique. According to the Standard Model of elementary particle physics, to each particle exists an antiparticle that is supposed to behave exactly the same way. Thus, “anti-people” in an “anti-world” would observe the same laws of physics, or make the same experiences in general, as we do. This postulate is, however, difficult to prove, since it is almost impossible to perform measurements on antimatter: whenever an antiparticle meets is matter-counterpart, both particles annihilate, accompanied by the creation of energy.
