Abstract
Abstract Room‐temperature sodium–sulfur (RT Na–S) batteries have been regarded as promising energy storage technologies in grid‐scale stationary energy storage systems due to their low cost, natural abundance, and high‐energy density. However, the practical application of RT Na–S batteries is hindered by low reversible capacity and unsatisfying long‐cycling performance arising from the severe shuttle effect and sluggish S redox kinetics. This review provides an overview of recent efforts for the optimization strategies of the electronic structure of catalysts via catalyst engineering to enhance the adsorption and catalytic activity toward soluble long‐chain sodium polysulfides (NaPSs). Finally, the current challenges and prospects for further optimization strategies of catalysts, understanding catalysis and structural evolution mechanism, and achieving practical applications are highlighted to meet the commercial requirements of RT Na–S batteries.

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
