Pressure Synthesis

The P1̄-MgN3 and P1̄-MgN4 are predicted to become energetically stable under pressure, suggesting that it may be prepared by high-pressure synthesis. P1̄-MgN3 and P1̄-MgN4 are expected to release an enormously large amount of energy (2.83 and 2.01 kJ g−1). The present study encourages experimental exploration of these promising materials in the future.

We predicted several N-rich structures under high pressure. C2/c-SrN4 can make the ambient-pressure recovery possible. The energy densities for C2/m-SrN3 and P1̄-SrN5 are 1.08 and 1.09 kJ g−1, respectively, similar to that of common energy materials.

Set Up

The future High Energy Materials Science Beamline HEMS at the new German high brilliance synchrotron radiation storage ring PETRA III [1] will have a main energy of 120 keV, will be fully tunable in the range of 50 to 300 keV, and will be optimized for sub-micrometer focusing with Compound Refractive Lenses and Kirkpatrick-Baez Multilayer mirrors. Design and construction is the responsibility of the Research Center Geesthacht, GKSS, with approximately 70 % of the beamtime being dedicated to Materials Research, the rest reserved for “general physics” experiments covered by DESY, Hamburg. Fundamental research will encompass metallurgy, physics and chemistry. For first experiments in investigating grain-grain-interactions a dedicated 3D-microstructure-mapper will be designed. Applied research for manufacturing process optimization will benefit from the high flux in combination with ultra-fast detector systems allowing complex and highly dynamic in-situ studies of microstructural transformations. The beamline infrastructure will allow easy accommodation of large user provided equipment. Experiments targeting the industrial user community will be based on well established techniques with standardised evaluation, allowing "full service" measurements. Environments for strain mapping [2] on large structural components up to 1 t will be provided as well as automated investigations of large numbers of samples, e.g. for tomography and texture determination. The current design for the beamline (P07 in sector 5 of the future experimental hall) consists of a nearly five meter in-vacuum undulator source (U19-5) optimized for high energies, a general optics hutch, an in-house test facility and three independent experimental hutches working alternately, plus additional set-up and storage space for long-term experiments. HEMS should be operational in spring 2009 as one of the first beamlines running at PETRA III.

Power Sources

In order to resolve environmental and sustainable energy concerns, significant efforts are required to find ways to minimise the use of fossil fuels and to shift to renewable energy resources such as solar, wind, and geothermal power generation. The key to success lies in developing reliable large scale high power energy storage devices. The lithiumair battery has been suggested as one candidate because of its exceptionally high energy storage capacity. Non-aqueous metal-air batteries utilising alkali and alkaline earth metal anodes also offer great gains in energy density over the state-of-the-art Li-ion battery. They are also unique power sources because the cathode active material (oxygen) does not have to be stored in the battery but can be accessed from the atmosphere. Moreover, alkali and alkaline earth elements are much more abundant than lithium and therefore would offer a more sustainable energy storage solution for even beyond the long-term. This work is to enable the uptake of this technology by fully analysing its principle and by exploring the application of nanostructured catalytic cathode materials. The potential of alkali and alkaline earth metal-air batteries will be demonstrated by their electrochemical cycling performance and will be compared with the lithium-air battery. The challenging issues will be discussed according to experimental observations.
