Wetting Interactions Between Porous Carbon Hosts and Liquid Sodium-Potassium Alloys Toward Their Use in Negative Electrodes of Alkali-Metal Batteries
Johannes Baller, André Hilger, Naiyu Qi +8
Batteries with liquid alkali-metal negative electrodes offer a route to compact, high-performance energy storage. Innovation in alkali-metal management, i.e., controlled storage, r…
Quantifying local heterogeneities in the 3D morphology of X-PVMPT battery electrodes based on FIB-SEM measurements
L. Dodell, M. Neumann, M. Osenberg +5
Organic electrode-active materials (OAMs) not only enable a variety of charge and storage mechanisms, but are also safer for the environment and of lower cost compared to materials…
Data-driven stochastic 3D modeling of the nanoporous binder-conductive additive phase in battery cathodes
Phillip Gräfensteiner, Markus Osenberg, André Hilger +5
A stochastic 3D modeling approach for the nanoporous binder-conductive additive phase in hierarchically structured cathodes of lithium-ion batteries is presented. The binder-conduc…
Unveiling the impact of crosslinking redox-active polymers on their electrochemical behavior by 3D imaging and statistical microstructure analysis
Marten Ademmer, Po-Hua Su, Lukas Dodell +8
Polymer-based batteries offer potentially higher power densities and a smaller ecological footprint compared to state-of-the-art lithium-ion batteries comprising inorganic active m…
Roadmap for focused ion beam technologies
Katja Höflich, Gerhard Hobler, Frances I. Allen +29
The focused ion beam (FIB) is a powerful tool for the fabrication, modification and characterization of materials down to the nanoscale. Starting with the gallium FIB, which was or…
Quantitative comparison of different approaches for reconstructing the carbon-binder domain from tomographic image data of cathodes in lithium-ion batteries and its influence on electrochemical properties
Benedikt Prifling, Matthias Neumann, Simon Hein +10
It is well known that the spatial distribution of the carbon-binder domain (CBD) offers a large potential to further optimize lithium-ion batteries. However, it is challenging to r…
Classification of FIB/SEM-tomography images for highly porous multiphase materials using random forest classifiers
Markus Osenberg, André Hilger, Matthias Neumann +6
FIB/SEM tomography represents an indispensable tool for the characterization of three-dimensional nanostructures in battery research and many other fields. However, contrast and 3D…
Characterization of the 3D microstructure of Ibuprofen tablets by means of synchrotron tomography
Matthias Neumann, Ramon Cabiscol, Markus Osenberg +4
We present a methodology to characterize the 3D microstructure of Ibuprofen tablets, which strongly influences the strength and solubility kinetics of the final formulation, by mea…
