Figure 5. Ternary diagrams of (A) effective diffusivity (D_eff), (B) reciprocal of tortuosity factor (1/τ²), and (C) specific interface area (A_s). The total volume fraction of solid electrolyte (ϵ_SE) is on the horizontal axis (in red), the fraction of cathode active material (ϵ_CAM) is on the vertical left-hand axis (in green), and the porosity (ϵ_pore) is on the vertical right-hand axis (in black). The labels (a), (b), and (c) in (A) correspond to the microstructures in Figure 4A-C, respectively. There are three auxiliary lines to aid in reading the phase fractions of Point (c) in (A), where the dashed green line indicates 64% CAM, the dashed black line indicates the 13% porosity, and the dashed red line indicates 23% SE. SE: Solid electrolyte; CAM: cathode active material.
