“…A few authors have investigated the contribution of concentrationdependent elastic constants [4][5][6][7][8][9][10] and concentration-dependent effective diffusivity [7,8,11,12] in the Li flux and resulting LIB electrode stress-state. Regarding the former, Yang et al [8] and He et al [10] used a linear Li-content-dependent Young's modulus in Si and Si-graphite, respectively.…”

“…Regarding the former, Yang et al [8] and He et al [10] used a linear Li-content-dependent Young's modulus in Si and Si-graphite, respectively. In their work [8,10], the Larche-Cahn chemical-potential approach [2] for a binary-alloy solid solution was employed. He et al [10] expressed their modifi cation of Eq.…”

“…While several works have considered the effects of the hydrostatic term, [1][2][3][4][5][6][7][8][9][10][11][12] very few have actually included the last two terms (σ kk σ ii and σ k j σ k j ) of the chemical potential in their analysis. [13][14][15][16] Most of the works neglect these terms since…”
