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…
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…
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…
