Layered LiCoO[sub 2] with a Different Oxygen Stacking (O2 Structure) as a Cathode Material for Rechargeable Lithium Batteries
Bibliographic record
Abstract
was prepared from by ion exchange in LiBr dissolved in hexanol. The structure of was investigated by X‐ray diffraction and in situ X‐ray diffraction during electrochemical charging. The possibility of application as cathode materials in rechargeable lithium batteries was investigated. We find that the electrochemical properties of as cathodes in lithium batteries are competitive with "conventional: . During cycling, the O2 structure of remains stable and does not convert to the thermodynamically stable . Both O2 and show a strong feature in their differential capacity vs. voltage at x near one‐half, which is probably caused by the ordering of Li atoms within each layer, suggesting that this is not strongly perturbed by the details of the stacking of the " " sheets. Finally, the reactivity of with electrolyte was studied by differential scanning coulometry of charged cathodes and compared to that of conventional . shows similar reactivity. © 2000 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.
