Bibliographic record
Abstract
Abstract Dual‐salt magnesium/lithium‐ion batteries (MLIBs) benefit from fast lithium ion diffusion on the cathode side while providing safety due to the dendrite‐free Mg 2+ stripping/plating mechanism on the anode side. Bulk MoS 2 (B‐MoS 2 ), as a cathode for magnesium‐ion batteries (MIBs), suffers from low conductivity and relatively van der Waals gaps and, consequently, resists against divalent Mg 2+ insertion due to the high Coulombic interactions. In MLIBs, it exhibits a Daniell‐cell type mechanism with the sole accommodation of Li + . In this paper, the synthesis of a 1T/2H mixed‐phase MoS 2 (MP‐MoS 2 ) modified with a hyperbranched polyethylene ionomer, I@MP‐MoS 2 , for high‐capacity MLIBs with a distinct Mg 2+ /Li + co‐intercalation mechanism is reported. Benefiting from the enhanced conductivity (due to 53% metallic 1T phase), expanded van der Waals gaps (79% expansion compared to B‐MoS 2 , 1.11 vs 0.62 nm), and enhanced interactions with THF‐based electrolytes following the modification, I@MP‐MoS 2 shows a dramatically increased Mg 2+ storage compared to its parent analogue (144 mAh g −1 vs ≈2 mAh g −1 at 20 mA g −1 ). In MLIBs, I@MP‐MoS 2 is demonstrated to exhibit remarkable specific capacities up to ≈270 mAh g −1 at 20 mA g −1 through a Mg 2+ /Li + co‐intercalation mechanism with 87% of capacity retention over 200 cycles at 100 mA g −1 .

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.
