Transition of the Reaction from Three‐Phase to Two‐Phase by Using a Hybrid Conductor for High‐Energy‐Density High‐Rate Solid‐State Li‐O<sub>2</sub> Batteries
Bibliographic record
Abstract
Abstract Solid‐state Li‐O 2 batteries possess the ability to deliver high energy density with enhanced safety. However, designing a highly functional solid‐state air electrode is the main bottleneck for its further development. Herein, we adopt a hybrid electronic and ionic conductor to build solid‐state air electrode that makes the transition of Li‐O 2 battery electrochemical mechanism from a three‐phase process to a two‐phase process. The solid‐state Li‐O 2 battery with this hybrid conductor solid‐state air electrode shows decreased interfacial resistance and enhanced reaction kinetics. The Coulombic efficiency of Li‐O 2 battery is also significantly improved, benefiting from the good contact between discharge products and electrode materials. In situ environmental transmission electron microscopy under oxygen was used to illustrate the reversible deposition and decomposition of discharge products on the surface of this hybrid conductor, visually verifying the two‐phase reaction.

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.
