Abstract
The high ionic conductivity, air/humidity tolerance, and related chemistry of Li3MX6 solid-state electrolytes (SSEs, M is a metal element, and X is a halogen) has recently gained significant interest. However, most of the halide SSEs suffer from irreversible chemical degradation when exposed to a humid atmosphere, which originates from hydrolysis. Herein, the function of the M atom in Li3MX6 was clarified by a series of Li3Y1–xInxCl6 (0 ≤ x < 1). When the ratio of In3+ was increased, a gradual structural conversion from the hexagonal-closed-packed (hcp) anion arrangement to cubic-closed-packed (ccp) anion arrangement has been traced. Compared to hcp anion sublattice, the Li3MX6 with ccp anion sublattice reveals faster Li+ migration. The tolerance of Li3Y1–xInxCl6 towards humidity is highly improved when the In3+ content is high enough due to the formation of hydrated intermediates. The correlations among composition, structure, Li+ migration, and humidity stability presented in this work provide insights for designing new halide-based SSEs.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
