Modeling and simulation of inhomogeneities in a 18650 nickel-rich, silicon-graphite lithium-ion cell during fast charging
Johannes Sturm,Alexander Rheinfeld,Ilya Zilberman,Franz B. Spingler,Stephan Kosch,Fabian Frie,Andreas Jossen +6 more
TL;DR: In this article, a multi-dimensional model consisting of several newman-type electrochemical models (p2D) coupled to an electrical-thermal cell domain model is used for model parameterization and validation.

Simulation and Measurement of the Current Density Distribution in Lithium-Ion Batteries by a Multi-Tab Cell Approach
Simon V. Erhard,Patrick J. Osswald,Peter Keil,Eike Höffer,Manuel Haug,Andreas Noel,Jörn Wilhelm,Bernhard Rieger,Korbinian Schmidt,Stephan Kosch,Frank M. Kindermann,Franz B. Spingler,Hauke Kloust,Torge Thoennessen,Alexander Rheinfeld,Andreas Jossen +15 more
TL;DR: In this article, a single-layer NMC/graphite pouch cell is investigated by means of differential local potential measurements during various operation scenarios and the results indicate that cell inhomogeneity is positively coupled to temperature, i.e. the lower the temperature, the more uniform the electrodes will be utilized.
Multi-directional laser scanning as innovative method to detect local cell damage during fast charging of lithium-ion cells
Bernhard Rieger,Simon F. Schuster,Simon V. Erhard,Patrick J. Osswald,Alexander Rheinfeld,Christopher Willmann,Andreas Jossen +6 more
TL;DR: In this paper, Li et al. measured the thickness change of a pouch cell at multiple positions during operation and disclosed a local overshoot in thickness change during fast charging near the current collector tabs at 25°C, which significantly increases at 17°C and is not detectable at 40°C.

Increasing the Discharge Rate Capability of Lithium-Ion Cells with Laser-Structured Graphite Anodes: Modeling and Simulation
Jan Bernd Habedank,Ludwig Kraft,Alexander Rheinfeld,Christina Krezdorn,Andreas Jossen,Michael F. Zaeh +5 more
TL;DR: In this paper, a three-dimensional model of a representative hole structure is developed, accounting for charge and mass transport throughout the cell layers and one-dimensional diffusion within radial-symmetric particles.
