Synergistic Modulation of Cationic Preferential Adsorption and Anionic Solvation Structure Reconstruction for Enhanced Stability of Zinc Anode
Bibliographic record
Abstract
Abstract Rechargeable aqueous zinc‐ion batteries (AZIBs) with low cost and high safety are promising for energy storage. However, challenges such as the hydrogen evolution reaction, corrosion, and dendrite growth diminish the stability and reversibility of the zinc anode. Herein, zirconium oxychloride is used as an electrolyte additive to address these issues via synergistic modulation. Experimental and theoretical results reveal that the cations (ZrO 2+ ) preferentially anchor to the Zn anode, forming a water‐poor electrical double layer that alters zinc ion migration pathways and restrains side reactions. Meanwhile, the anions (Cl − ) enter the solvation‐sheath structure of zinc ions, reconstruct the hydrogen‐bond network of the electrolyte, and weaken water reactivity, eliminating dendrite growth and promoting anticorrosion behavior. Consequently, the Zn||Zn symmetric cell confers a lifespan of 1800 h at 3 mA cm −2 for 1 mAh cm −2 . Zn||Cu half‐cells maintain a high coulombic efficiency of 99.8% after 1900 cycles. When matched with NaV 3 O 8 ·1.5H 2 O (NVO) cathode, the Zn||NVO full‐cell achieves a capacity retention of 77% at 5.0 A g −1 after 1000 cycles. This work provides a solution for developing high‐performance AZIBs.

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.
