An orderly arranged dual-role MIL-53(Al) nanorods array rooted on carbon nanotube film for long-life and stable lithium-sulfur batteries
Bibliographic record
Abstract
It is of great value to synchronously resolve the critical issues of the polysulfide shuttle and dendrite growth in lithium-sulfur (Li-S) batteries. Herein, a bifunctional Al-based Material of Institute Lavoisier-53 (MIL-53(Al))/carbon nanotube (MIL-53/CNT) composite is reported for this matter, which was constructed by growing an ordered MIL-53(Al) nanorods array on the CNT film. For the sulfur cathode, the proposed structure serves as a multifunctional interlayer to block polysulfides and accelerate their catalytic conversion, thus efficaciously inhibiting the shuttle effect. Meanwhile, when applied as the anode host material (Li@MIL-53/CNT), the flexible CNT film serves as a self-standing framework to accommodate Li metal and alleviate the volume expansion, while the uniform ion channels built by the MIL-53(Al) nanorods array along with the abundant oxygen groups can homogenize Li ion diffusion, enabling a steady Li plating/stripping behavior and limiting the dendrite growth. Not surprisingly, Li-S full battery with MIL-53/CNT interlayer and Li@MIL-53/CNT anode delivers an appreciable specific capacity of 735 mAh·g−1 and excellent cycle durability at 5 C, presenting a limited capacity decay of 0.03% per cycle in 500 cycles. Besides, an impressive cycle stability and rate capability are also achieved at high-sulfur loading and lean electrolyte conditions.

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.
