Abstract
The structure of the coprecipitated precursor to the positive electrode material, (NMC), is typically synthesized via a coprecipitation reaction and assumed to be or . The coprecipitation reaction and its products are not thoroughly understood. Here, pure phase is synthesized in the presence of aqueous ammonia, yielding dense and spherical particles. was found to readily oxidize in air, especially during heating. The obtained product was analyzed with powder X-ray diffraction and thermogravimetric analysis. The results indicate that undergoes oxidation to the oxyhydroxide phase, . Heating also resulted in an increase in tap density of the oxyhydroxide; the final tap density of the material was found to be .

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
