Elliptical Silicon Nanowire Covered by the SEI in a 2D Chemo-Mechanical Simulation
Raphael Schoof, Lukas Köbbing, Arnulf Latz +2
Understanding the mechanical interplay between silicon anodes and their surrounding solid-electrolyte interphase (SEI) is essential to improve the next generation of lithium-ion ba…
Comparison of Different Elastic Strain Definitions for Largely Deformed SEI of Chemo-Mechanically Coupled Silicon Battery Particles
Raphael Schoof, Giuseppe Fabian Castelli, Willy Dörfler
Amorphous silicon is a highly promising anode material for next-generation lithium-ion batteries. Large volume changes of the silicon particle have a critical effect on the surroun…
Residual Based Error Estimator for Chemical-Mechanically Coupled Battery Active Particles
Raphael Schoof, Lennart Flür, Florian Tuschner +1
Adaptive finite element methods are a powerful tool to obtain numerical simulation results in a reasonable time. Due to complex chemical and mechanical couplings in lithium-ion bat…
Modeling and Simulation of Chemo-Elasto-Plastically Coupled Battery Active Particles
Raphael Schoof, Johannes Niermann, Alexander Dyck +2
As an anode material for lithium-ion batteries, amorphous silicon offers a significantly higher energy density than the graphite anodes currently used. Alloying reactions of lithiu…
Adaptive mesh refinement for the Landau-Lifshitz-Gilbert equation
Jan Bohn, Willy Dörfler, Michael Feischl +1
We propose a new adaptive algorithm for the approximation of the Landau-Lifshitz-Gilbert equation via a higher-order tangent plane scheme. We show that the adaptive approximation s…
Simulation of the Deformation for Cycling Chemo-Mechanically Coupled Battery Active Particles with Mechanical Constraints
R. Schoof, G. F. Castelli, W. Dörfler
Next-generation lithium-ion batteries with silicon anodes have positive characteristics due to higher energy densities compared to state-of-the-art graphite anodes. However, the la…
Transformation-optics modeling of 3D-printed freeform waveguides
Aleksandar Nesic, Matthias Blaicher, Emilio Orlandini +10
Multi-photon lithography allows to complement planar photonic integrated circuits (PIC) by in-situ 3D-printed freeform waveguide structures. However, design and optimization of suc…
The elastic inclusion problem in the (amplitude) phase field crystal model
Marco Salvalaglio, Karthikeyan Chockalingam, Axel Voigt +1
In many processes for crystalline materials such as precipitation, heteroepitaxy, alloying, and phase transformation, lattice expansion or compression of embedded domains occurs. T…
Coupled Mode Equation Modeling for Out-of-Plane Gap Solitons in 2D Photonic Crystals
Tomas Dohnal, Willy Doerfler
Out-of-plane gap solitons in 2D photonic crystals are optical beams localized in the plane of periodicity of the medium and delocalized in the orthogonal direction, in which they p…
