Neue Carbodiimide der 3d-Übergangsmetalle : Synthese, Struktur und magnetische Eigenschaften

Based on the results of the author’s own diploma thesis, several neutron diffraction experiments have been carried out to determine the antiferromagnetic structure of MnNCN. In the ordered state, two different orientations of the manganese spins could be detected. With the preparation of CoNCN and NiNCN, two hitherto unknown transition metal carbodiimides were synthesized by a newly developed synthesis method via the corresponding hydrogencyanamides M(HNCN)_2. The crystal structure of the isotypical compounds CoNCN and NiNCN determined from single crystal data sets can be described as a variation of the NiAs structure elongated in c direction. Magnetic measurements show significantly reduced effective magnetic moments compared to dilute systems and maxima of susceptibility at comparatively high temperature. Both aspects are signs of very strong antiferromagnetic interactions between the metal ions. The hydrogencyanamides mentioned above are also new compounds and the first ones of their kind containing cations with unpaired electrons. The determination of the magnetic properties showed them to be ferromagnetic with very low Curie points. For CdNCN, Raman data were recorded, whereby the structure published before could be clearly refuted. Both nitrogen atoms were determined to show exactly the same distance to the carbon atom, and the shape of the anion is linear. The NCN2- unit consequently adopts the carbodiimide conformation. Thus, the reported C–N and Cd–N bond lengths could be corrected

Deposition of Corrosion Preventing Coatings for Dual-Ion Batteries

Commercial lithium ion batteries (LIB) are built with liquid electrolytes containing organic carbonates and lithium hexafluorophosphate (LiPF6). The flammability of these carbonates implies safety risks which could be avoided by replacing the electrolyte mixtures by ionic liquids (ILs), e.g. based on anions like bis(trifluoromethylsulfonyl)imide (TFSI). Additionally, LiPF6 (which also tends to thermal decomposition) can be substituted by appropriate conducting salts, e.g. LiTFSI. Since these components show negligible vapor pressure and high thermal stability, the danger of thermal runaway is minimized, but some problems are still to be solved. In this context, anodic dissolution of the aluminum current collector is a very important issue. To overcome this drawback, innovative protection coatings are deposited on aluminum foils by magnetron sputtering

Development of electronically conductive corrosion protection layers for current collectors in innovative dual-ion cells

Due to the intercalation of both cations and anions in this new type of battery, the voltage can reach values above 5 V. This can lead to the corrosion of the aluminum current collector if the electrolyte containing fluorinated anions is used. However, the advantages of ionic liquid over organic solvent based solutions overbalance and there is no useful option to replace them. Therefore it is necessary to protect the aluminum current collector with an electronically conductive, defect free and stable coating. Several coating methods and material compositions were tested and the performance of the coatings are investigated in long term cell tests with cyclic voltammetry
