Using the new Materials Project and the legacy version, I analyzed the interface reactivity between a pair of phases. The results are actually different and I don’t quite understand the result produced by the new Materials Project.
For example, with Li3B11O18-C interface, the legacy MP predicts stability, while the new MP predicts reactivity via Li3B11O18 → Li3BO3 + 5 B2O3. As Li3B11O18 is on the convex hull, I suppose the this reaction is not energetically favorable.
Could someone help explain the result, and the discrepancy between two MP versions?
