Derived diffusion coefficients in dependence on the time interval $\left(t_1,t_2\right)$ for parameters as in Figure 8, but with higher galvanostatic current i _GS=0.1Am⁻². See Figure 7 for explanations. The given diffusion coefficients (dashed horizontal lines) are D _exa=10⁻¹⁴ (a), ${10}^{-15}$ (b), and 10⁻¹⁶ m² s⁻¹ (c). Further parameters: T=−40 °C, k=10⁻⁸ mol m⁻²s⁻¹, x₀=0.9.
