Abstract
A rapid solid‐state flash heat and quench (FHQ) synthesis approach has been used to facilitate the rapid formation of layered NCA Li‐ion cathodes with low structural defects. LiNi x Co y Al z O 2 (NCA) materials prepared by FHQ reveal impressive gravimetric capacity at C/10 and 10C discharge rates (195 and 150 mAh g −1 , respectively) after a few minutes of heating a co‐precipitate mixture with LiOH, providing >95% reduction in energy needed for heat‐treatment versus conventional solid state synthesis routes. Combined X‐ray diffraction, neutron scattering with pair‐distribution‐function analysis, and X‐ray absorption spectroscopy for a range of heat‐treated samples are used to identify the point at which Ni 2+ −Li + antisite defects are minimized in these materials, which is critical to their electrochemical performance.

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
