Single Bath, Pulsed Electrodeposition of Copper-Tin Alloy Negative Electrodes for Lithium-ion Batteries
Bibliographic record
Abstract
Single-bath, pulsed electrodeposition of Cu-Sn alloy films was performed in a bath containing Lucent Technology's SnTech plating solution and copper sulfate. Films with varying Cu-Sn stoichiometries were deposited. Deposited films were between and 6 μm thick. These films were used as working electrodes in Li/Cu-Sn electrochemical cells to test their suitability as negative electrodes for Li-ion cells. As the Cu content in the film is increased, specific capacity is sacrificed for capacity retention. Films with a Cu-Sn atomic ratio of 0.27 (high Sn content) had a maximum specific capacity of 500 mAh/g, however capacity retention is only about 20% of the original capacity after 40 cycles. High Cu content films (Cu-Sn atomic ratio of 3.83) yield specific capacities near 200 mAh/g, with 80% capacity retention after 40 cycles. © 2003 The Electrochemical Society. All rights reserved.

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.
