Abstract
Abstract Two‐dimentional (2D) Ti 3 C 2 T x MXene has attracted significant attention in non‐lithium‐ion batteries due to its excellent electrical conductivity, high volumetric capacity, and ability to accommodate intercalants. Rechargeable magnesium batteries with Mg metal anodes are noted for their high theoretical energy density, potential safety, earth abundance, dendrite‐free Mg 2+ plating/stripping mechanism on the anode side, and low cost. Nevertheless, owing to the large polarity of divalent Mg 2+ ions, the insertion of Mg 2+ into the MXene layers suffers from sluggish kinetics, limiting the performance for storage of Mg 2+ ions. Herein, a simple self‐assembly strategy is demonstrated to achieve high magnesium ion storage capability with pillar‐structured Ti 3 C 2 T x MXene by intercalating a hyperbranched polyethylene ionomer containing quaternary ammonium ions. The ionomer intercalation/modification leads to the expansion of interlayer spacing of the MXene and, meanwhile, improves its affinity to low‐polarity THF‐based electrolyte. The delaminated ionomer‐modified MXene shows significantly improved electrochemical performance as a cathode material for Mg batteries. It shows a promising cycling stability with a capacity retention of 86% after 400 cycles at 200 mA g −1 , as well as outstanding high‐rate performance with a capacity of 110 mAh g −1 retained at 1,000 mA g −1 relative to 213 mAh g −1 at 20 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 it
