In this study, zinc bis(aminosulfate) (Zn(NH₂SO₃)₂) with a monovalent anion, NH₂SO₃⁻, was synthesized and dissolved in different ratios of dimethyl sulfoxide (DMSO) and H₂O as electrolytes for Zn-ion batteries (ZIBs). From the perspective of game theory, the influences of DMSO and H₂O on the solvation structure and electrochemical performance of the Zn(NH₂SO₃)₂ based electrolytes has been meticulously discussed. Computations and spectra analysis indicate that DMSO molecules are reluctant to penetrate the primary solvation structure of Zn²⁺ ions. Indeed, increasing DMSO in electrolytes can induce a transition from solvent-separated ion pairs (SSIP) to contact ion pairs (CIP), resulting in an enrichment of anions in the primary solvation structure. This alteration can significantly suppress parasitic reactions, enhance nucleation density, and refine the deposition morphology during the Zn plating process, leading to superior cyclic stability and high coulombic efficiency (CE) of Zn//Cu and Zn//Zn cells. However, the enrichment of anions in the primary solvation structure also inhibits the activity of Zn²⁺ ions, amplifies the polarization effect, and engenders a sluggish ionization dynamics, resulting in the low energy conversion efficiency of the battery. These findings underscore the influence of the anion ratio within the primary solvation structure on electrochemical properties of electrolytes for ZIBs, which may be a pivotal determinant in the Zn deposition process.</div></div>","PeriodicalId":15728,"journal":{"name":"Journal of Energy Chemistry","volume":"104 ","pages":"Pages 644-654"},"PeriodicalIF":13.1,"publicationDate":"2025-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143422415","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pyrrole-type single-atom catalysts (SACs) with unique electronic structures have emerged as promising electrocatalysts. In this work, we combine density functional theory (DFT) calculations and experimental studies to systematically explore the structure-activity relationships and potential of pyrrole-type transition metal-N₃ (TM-po-N₃) as bifunctional catalysts.
