Electrochemistry of Cu<sub>x</sub>Si<sub>1−x</sub>Alloys in Li Cells
Bibliographic record
Abstract
The structure and electrochemistry in lithium cells of sputtered thin films and ball milled alloys in the Cu-Si system (0 ≤ x ≤ 0.60 in Cu x Si 1−x ) were investigated. Both thin films and ball milled Cu-Si alloys showed the co-existence of amorphous Si and a nanocrystalline Cu 3 Si phase. The lithiation potential of Cu-Si alloys was found to be significantly shifted to potentials below that of pure Si. In addition, the Cu 3 Si phase was found to be involved in the electrochemical reaction of the alloys with lithium, however not all of the Si could be reacted with Li to its full theoretical extent. This suggests that a ternary Cu-Li-Si phase may be formed at full lithiation of these alloys.

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.
