Abstract
Abstract Rechargeable metal‐air batteries, such as Li‐air and Zn‐air batteries, have gained renewed interest because of their high theoretical energy density, safety and low cost. The air electrode, with bifunctional electrocatalysts for the oxygen reduction reaction (ORR) and the oxygen evolution reaction (OER), plays the most important role in determining battery performance. Direct deposition of catalysts on the air electrode, using methods such as electrodeposition, electroless deposition, chemical vapor deposition (CVD) and physical vapor deposition (PVD), is shown to be a viable way to fabricate durable and active catalysts with high efficiency and low cost. This review examines recent research activities which apply direct deposition methods to prepare bifunctional catalysts. The benefits and drawbacks of these methods are compared to provide guidelines for their application.

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
