Amorphous silicon offers significantly higher energy density than graphite anodes in lithium-ion batteries, but undergoes large volume changes during lithiation/delithiation cycles, leading to plastic deformation. This work formulates and compares rate-independent and rate-dependent plasticity models to capture the chemo-elasto-plastic behavior of silicon anodes, using advanced numerical techniques for efficient simulation.
