We note that this analysis considers only the most favorable angle of dendritic propagation, which is directly relevant to the amount of material that must be plated prior to failure. A smaller propagation angle implies that more metal plating must occur before dendrite-induced shorting, while a larger angle implies the opposite. However, this analysis does not directly consider the exact value of the driving force after the crack kinks, nor does it investigate the impact of the electric field on propagation. Furthermore, we have assumed the electrolyte to be isotropic and homogeneous. In reality, electrolytes possess microstructural features and defects which may impact the mechanics and thus morphology of propagating flaws.
