Abstract
Abstract Developing an efficient cathode is essential to obtain high rate capability and rechargeable lithium oxygen (Li‐O 2 ) batteries. Herein, ruthenium (Ru)‐functionalized hierarchical carbon nanocages (hCNCs) are synthesized and employed as a cathode catalyst for Li‐O 2 batteries. The as‐prepared cathode exhibits high discharge capacity, low charge potential (8135 mA h g −1 with 3.85 V charge potential at a current density of 0.08 mA cm −2 ), outstanding rate capability (3416 mA h g −1 at a current density of 0.48 mA cm −2 ) and good stability up to 78 cycles at a limited capacity of 500 mA h g −1 . Such excellent battery performance is ascribed to the synergistic effect of the interconnected hierarchically porous structure of hCNCs, which can facilitate effective electrolyte immersion and efficient Li + /O 2 mass transport, and the high catalytic activity of Ru nanoparticles.

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
