Nanoreactor‐Driven Uniform Nano ZnS Deposition in Tunable Porous Carbon Spheres for High‐Performance Zn‐S Batteries
Bibliographic record
Abstract
Abstract Zn‐S batteries have garnered widespread attention in recent years due to their higher safety and low cost. However, challenges such as incomplete sulfur redox reactions and the tendency of ZnS to agglomerate have impeded the continued advancement of high‐performance Zn‐S batteries. Hollow hierarchical porous carbon spheres (HCs) are designed as efficient sulfur hosts for Zn‐S batteries. The tailored HCs, featuring optimized shell thickness, hierarchical porosity, facilitate uniform nano‐ZnS deposition, and improve ion/electron transport, which are revealed by in situ impedance technology. This nano reactor design ensures highly reversible S‐ZnS conversion, reducing internal polarization and mitigating structural degradation. Electrochemical tests demonstrate outstanding cycling stability, with minimal capacity decay (0.068%) over 500 cycles, and 463 mAh g −1 reversible capacity at 5 A g −1 . Finite element simulations further confirm the effective stress dispersion of HCs, preserving electrode integrity. This work provides a promising strategy for developing high‐performance Zn‐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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
