Abstract
Abstract Lithium‐sulfur batteries have evoked intensive attention caused by the urgent requirement of energy storage devices with higher energy density, long cycle life, and low cost. However, the insulating nature and the soluble reaction intermediate products still hinder its large‐scale industry and acceptance by the market. Tremendous efforts focus on the composite of polar material and non‐polar material to solve the weaknesses of material insulating nature and soluble reaction intermediate products. However, the linkage form between these two generic materials has been ignored. In this paper, by using typical Ni 2 P as polar material and graphene as non‐polar material, the reaction kinetics changes and its intrinsic theories on behavior enhancement have been proved, which construct different binding type between polar and non‐polar materials. The Ni 2 P/PrGO delivers an improved high specific capacity of 1254.6 mAh g ‐1 than Ni 2 P/rGO at 0.2 C. The relevant X‐ray photoelectron spectroscopy result and the in situ electrochemical impedance spectroscopy tests prove that the linkage state between polar and non‐polar material has strong influence on the sulfur cathode reaction kinetics. The enhanced reaction kinetics and polar adsorption behavior bring the soft pack battery testing unit over 150 stable cycles with decay ratio of 0.19% for each cycle.

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
