Abstract
Coin cells require small amounts of material, can have good reproducibility, are easily fabricated in large quantities and have small space requirements that allow many cells to be tested simultaneously under controlled conditions. If thin electrodes are used, concerns over bulk electrode issues can be alleviated, making coin cells an ideal research tool for testing new active materials, electrode material recipes, electrolytes and separators. This work focused on the choice of materials for the components in an alkaline Nickel-Zinc coin cell. The experiments showed that nickel should be used for all positive electrode side components, including the current collector, while tin should be used for all negative electrode side components. A non-woven separator as well as a microporous separator are both required for long cycle life. Nickel-Zinc coin cells created in this work achieved Nickel active material utilizations over 100% and cycle lives of over 300 cycles with unoptimized electrode materials. The procedures and recipes developed may be of value for researchers working on rechargeable Zn-air cells.

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 it
