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 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.
