Chemomechanical modeling of lithiation-induced failure in high-volume-change electrode materials for lithium ion batteries (2017, background): “(8) is only a matter of computational convenience.(66) A concentration-independent diffusivity gives rise to a diffuse-phase (single-phase) boundary.”
Electrochemomechanical degradation of high-capacity battery electrode materials (2017, background): “During lithiation, newly created excess volume due to Li insertion generates high compressive stress at the ACI, pushing the lithiated phase behind the moving interface outward [33,34,43,102,115,126].”
A chemo-mechanical model of lithiation in silicon (2014, unknown): “(9)), we simulate Li diffusion by solving a surrogate heat conduction problem, where the normalized Li concentration c is regarded as temperature T in heat conduction (Huang et al., 2013; Liu et al., 2011c; Pharr et al., 2012; Yang et al., 2012; Zhao et al., 2012).”
