Many attempts over the past decades have been made to resolve the lithium dendrite formation. Whereas the root-growing lithium whiskers at the low deposition rate regime and the fractal lithium dendrite at the high deposition rate regime are well investigated, the growth of mossy dendrites at normal charge conditions is not fully understood so far. This work proposes a phase-field method for simulating the mossy dendrite formation. By taking into account two kinds of lithium-ion migration behaviors in the solid electrolyte interphase (SEI), the fast migration pathway at the fractured SEI versus the slow migration pathway at the intact SEI, our simulation results reveal that the inhomogeneity of lithium-ion migration mechanism within the anode/electrolyte interface is the key to the formation of mossy lithium dendrites. |
