Percolation micro-model to predict the effective properties of the composite electrode with poly-dispersed particle sizes

▶ The model reveals the effect of particle size distributions on electrode properties. ▶ The properties include the TPB lengths and intra/inter particle conductivities. ▶ All the properties are presented in non-dimensional form to provide generality. ▶ Cathode may benefit from small mean particle sizes and narrow size distributions. ▶ Anode may benefit from large mean particle radii ratio and broad size distributions.
