Summary In this work, the microstructure of composite electrolyte is reconstructed by randomly packing cubes, and the charge transport process is simulated to calculate the effective conductivity ratio σ eff / σ 0 of the designated conducting phase. Effects of the volume fraction and the electrolyte particle size on σ eff / σ 0 are also examined. Results show that σ eff / σ 0 is independent of the particle size but sensitive to its volume fraction. Finally, a new formula is proposed to quickly predict the σ eff / σ 0 of the designated conducting phase in composite electrolyte with varying compositions.
