Material properties of electrodes and electrolytes along with cell parameters such as stack pressure and temperature have coupled, synergistic, and sometimes deleterious effects on fast-charging performance. We develop a new experimental testbed that allows precise and conformal application of electrode stack pressure. We focus on cell capacity degradation using single-layer pouch cells with graphite anodes, LiNi0.5Mn0.3Co0.2O2 (NMC532) cathodes, and carbonate-based electrolyte. In the tested range (10 – 125 psi), cells cycled at higher pressure show higher capacity and less capacity fading. Additionally, Li plating decreases with increasing pressure as observed with scanning electron microscopy (SEM) and optical imaging. While the loss of Li inventory from Li plating is the largest contributor to capacity fade, electrochemical and SEM examination of the NMC cathodes after XFC experiments show increased secondary particle damage at lower pressure. We infer that the better performance at higher pressure is due to more homogenous reactions of active materials across the electrode and less polarization through the electrode thickness. Our study emphasizes the importance of electrode stack pressure in XFC batteries and highlights its subtle role in cell conditions.}}, author = {{Cao, Chuntian and Steinrück, Hans-Georg and Paul, Partha P and Dunlop, Alison R. and Trask, Stephen E. and Jansen, Andrew and Kasse, Robert M and Thampy, Vivek and Yusuf, Maha and Nelson Weker, Johanna and Shyam, Badri and Subbaraman, Ram and Davis, Kelly and Johnston, Christina M and Takacs, Christopher J and Toney, Michael}}, issn = {{0013-4651}}, journal = {{Journal of The Electrochemical Society}}, keywords = {{Materials Chemistry, Electrochemistry, Surfaces, Coatings and Films, Condensed Matter Physics, Renewable Energy, Sustainability and the Environment, Electronic, Optical and Magnetic Materials}}, pages = {{040540}}, publisher = {{The Electrochemical Society}}, title = {{{Conformal Pressure and Fast-Charging Li-Ion Batteries}}}, doi = {{10.1149/1945-7111/ac653f}}, volume = {{169}}, year = {{2022}}, } @article{32108, author = {{Henksmeier, T. and Schulz, J.F. and Kluth, E. and Feneberg, M. and Goldhahn, R. and Sanchez, A.M. and Voigt, M. and Grundmeier, Guido and Reuter, Dirk}}, issn = {{0022-0248}}, journal = {{Journal of Crystal Growth}}, keywords = {{Materials Chemistry, Inorganic Chemistry, Condensed Matter Physics}}, publisher = {{Elsevier BV}}, title = {{{Remote epitaxy of InxGa1-xAs (0 0 1) on graphene covered GaAs(0 0 1) substrates}}}, doi = {{10.1016/j.jcrysgro.2022.126756}}, volume = {{593}}, year = {{2022}}, } @article{32432, author = {{Yang, Yu and Huang, Jingyuan and Dornbusch, Daniel and Grundmeier, Guido and Fahmy, Karim and Keller, Adrian and Cheung, David L.}}, issn = {{0743-7463}}, journal = {{Langmuir}}, keywords = {{Electrochemistry, Spectroscopy, Surfaces and Interfaces, Condensed Matter Physics, General Materials Science}}, pages = {{9257–9265}}, publisher = {{American Chemical Society (ACS)}}, title = {{{Effect of Surface Hydrophobicity on the Adsorption of a Pilus-Derived Adhesin-like Peptide}}}, doi = {{10.1021/acs.langmuir.2c01016}}, volume = {{38}}, year = {{2022}}, } @article{34207, abstract = {{AlSi casting alloys combine excellent castability with high strength.

By utilizing synchrotron radiation and photoelectron photoion coincidence spectroscopy, six important zirconium intermediates, as for instance Zr(C5H7O2)2(C5H6O2), and Zr(C5H6O2)2, are identified in the gas phase for the first time. The adiabatic ionization thresholds of intermediately formed zirconium species are estimated and the main products of their thermal decomposition, acetylacetone, acetylallene and acetone are characterized unambiguously and isomer-selectively. Based on all detected intermediates, we deduce the predominant pyrolysis pathways of the precursor in the temperature range from 400 to 900 K. Our findings are complemented by numerical simulations of the flow field in the microreactor, which show that the choice of dilution gas significantly influences the temperature profile and residence times in the microreactor, such that helium provides a more uniform flow field than argon and should preferentially be used.
