Effect of Cold-Working on the Discharge Performance of Commercially Pure Aluminum and AA7050 Alloy Anodes in Primary Alkaline Aluminum-air Battery
Bibliographic record
Abstract
This work evaluated the performance of annealed and cold-worked commercially pure Aluminum (AA1100) and AA7050 Aluminum alloy as the Aluminum-air battery (Al-air battery) anode in a 4 mol.l−1 KOH solution. The electrochemical performance, galvanostatic discharge behavior, and microstructure of the anodes after discharge were studied. Cold-worked anodes showed a more negative corrosion potential and a lower corrosion current density compared to annealed anodes, indicating a higher electrochemical activity and an enhanced anti-corrosion behavior. In addition, the anodic efficiency and capacity density of the cold-worked anodes increased significantly compared to the annealed anode by increasing the discharge current density from 20 mA.cm−2 to 100 mA.cm−2. The results of this work indicated that cold-worked pure Al and AA7050 Al alloy has better potential as anode materials in alkaline Al-air batteries than the annealed Al anode.

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.
