Layered Li[Ni[sub x]Co[sub 1−2x]Mn[sub x]]O[sub 2] Cathode Materials for Lithium-Ion Batteries
Bibliographic record
Abstract
The structure and electrochemical behavior of with and 3/8 is reported for the first time. is prepared by the simultaneous substitution of and for in X-ray diffraction patterns show these materials have a layered -type structure. Both with or 3/8 can deliver a stable capacity of about 160 mAh/g between 2.5 and 4.4 V vs. Li using a specific current of 40 mA/g. If the upper potential of cells with is reduced to 4.2 V vs. Li, its capacity retention behavior is improved and it gives a capacity of 136 mAh/g, which is very close to that of in the same potential window. Studies of the thermal stability of in electrolyte using differential scanning calorimetry indicate that the samples with and are more thermally stable than © 2001 The Electrochemical Society.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
