Surface Control and Multi-Composite Cathodes
Bibliographic record
Abstract
We report recent progress in surface control of cathode element particles. Re-crystallization of the surface layer can be obtained not only in olivines, but also in lamellar compounds, which results in an increase of the electrochemical properties. In addition, we take benefit of the stability of LiFePO 4 and the fact that it does not need protection against overcharge, by synthesizing multi-component particles formed by a core particle with higher working potential like LiMnPO 4 (4 V cell) and even LiMn 1.5 Ni 0.5 O 4 (5 V cell) surrounded by LiFePO 4 coated with carbon to the particles with LiFePO 4 . The remarkable improvement of the electrochemical properties obtained in this process gives evidence that the synthesis of such multi-component composites are promising to improve the energy density and high-rate performance of Li-ion batteries in the near future.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
