Fabrication of Nanoporous Copper Ribbons with a Broad Range of Pore Size and Its Application in Lithium-ion Batteries
Bibliographic record
Abstract
Nanoporous copper (NPC) ribbons with an average pore size of 5~500nm were fabricated by chemical/electrochemical dealloying of Mn55Cu45 alloy. The influence of different kinds of driving forces on Cu atoms surface diffusivity (Ds), which determines the pore sizes of the resultant NPC, was also systematically investigated. The Ds by chemical dealloying with and without surfactants is about 1.08×10-20 m2 s-1 and 1.79×10-18 m2 s-1, through which NPC with pore size of ~5nm and ~50nm was produced, while, in electrochemical dealloying with 0 V SCE potential, Ds and pore size increase to 1.16×10-15 m2 s-1 and ~500nm respectively. The three dimensional NPC ribbons with the largest pore size (500nm) was chosen as the current collectors to fabricate three dimensional tin thin-film anodes (3D-TTA) with homogeneous tin layers on the ligaments by electroless plating for lithium-ion batteries (LIBs). The 3D-TTA exhibits first discharge capacity of 790 mAh g-1, 45% capacity retention after 10 cycles, indicating a promising application in LIBs.

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.
