Fig. 2 — a Stability map. The color of each block in the lower triangle represents the median E_hull (bottom-left) of NASICONs that contain the metals on the x- and y-axis. The upper triangle shows the fraction of compounds (f_accessible) with $E_{hull} - S_{ideal} \times 1000 K \leq 0$ . b The distribution of E_hull (top) and f_accessible (bottom) as a function of Na content and polyanion composition. Polyanions are represented by their central cation, e.g., Si₂P indicates (SiO₄)₂(PO₄). Green (red) indicates good (poor) NASICON stability in a and b.
