Abstract
The thermal behavior of carbon-coated LiFePO4 cathode material was investigated using three different calorimetric techniques. Heat released during charge and discharge of cylindrical 18650 size cells was measured in an isothermal calorimeter. Accelerating rate calorimetry was used to investigate the cause of thermal runaway of the cylindrical 18650 size cells. On the other hand, differential scanning calorimeter was used to study the contribution of the delithiated carbon-coated LiFePO4 and the lithiated graphite to the overall thermal runaway through coin cells of 2032 size. The carbon-coated LiFePO4 showed very good thermal stability.

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
