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…
Predicting air flow in calendered paper sheets from -CT data: combining physics with morphology
Phillip Gräfensteiner, Andoni Rodriguez, Peter Leitl +10
Predicting the macroscopic properties of thin fiber-based porous materials from their microscopic morphology remains challenging because of the structural heterogeneity of these ma…
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…
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…
Assessing a Hydrodynamic Description for Instabilities in Highly Dissipative, Freely Cooling Granular Gases
Peter P. Mitrano, Vicente Garzó, Andrew M. Hilger +2
An intriguing phenomenon displayed by granular flows and predicted by kinetic-theory-based models is the instability known as particle "clustering," which refers to the tendency of…
