The optimal V_o2-Co(OH)F achieves an ultralow operating potential of −0.03 V vs. RHE at −100 mA cm⁻² and a remarkable NH₃ Faradaic efficiency (FE) of 98.4% at −0.2 V vs. RHE for NO₂RR, and a high formate FE of 98.03% for EGOR.

To overcome electrolyte-induced parasitic reactions, it is essential to understand the dynamic evolution of concentration-dependent metal ion solvation structures (MISSs). This study systematically reveals the solvation structure evolution of MgCl₂ aqueous solutions across a full concentration range (0–30 M) and its impact on electrochemical properties using molecular dynamics simulations and density functional theory calculations. Results indicate that six characteristic solvation configurations exist, exhibiting a dynamic, concentration-dependent inter-evolution defined as the solvation structure evolutionary processes (SSEP). The four-phase glass transition mechanism in solvation structure evolution is revealed by analyzing the percentage of each type of solvation structure in different concentrations. The study shows that conductivity is directly related to the dynamic transitions of dominant solvation structures, with a shift in the Mg²⁺ coordination mode—from octahedral through pentahedral intermediates to tetrahedral—revealing a concentration-dependent ion transport mechanism. At low concentrations, free-state stochastic diffusion predominates, reaching a maximum conductivity before transitioning to relay transport within a restricted network at high concentrations. Key contributions include: a general strategy for electrolyte design based on the solvation structure evolution process, which quantitatively correlates structural occupancy with migration properties, and the “Concentration Window” regulation model that balances high conductivity with reduced side reactions. These findings clarify the structural origins of anomalous conductivity in highly concentrated electrolytes and establish a mapping between microstructural evolution and macroscopic performance, providing a theoretical basis for engineering high-security electrolytes of AMIBs.</div></div>","PeriodicalId":15728,"journal":{"name":"Journal of Energy Chemistry","volume":"109 ","pages":"Pages 466-478"},"PeriodicalIF":13.1,"publicationDate":"2025-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144297699","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}

To address this issue, a general framework for evaluating the whole-process safety by integrating thermal and gas perspectives, involving dozens of multi-dimensional characteristic parameters obtained by experimental measurements and theoretical calculations, is proposed. Based on this framework, comparing the initial thermal hazards of lithium iron phosphate and nickel-cobalt-manganese lithium-ion batteries and quantifying the derived hazards of single-phase/multi-phase emissions considering battery venting gases and electrolyte solvent vapors, the significant hidden hazards of emissions dominated by reductive components that can lead to higher derived explosion and combustion risks within the external environment are identified, effectively updating the previous paradigm for evaluating cell-level thermal safety. For single-phase emissions with dominant reductive components, higher risks of low lower explosion limit and high laminar burning velocity are demonstrated; after considering typical solvent vapor types (dimethyl carbonate/ethyl methyl carbonate/diethyl carbonate) and specific mixing ratios, highly reductive multi-phase emissions still exhibit higher risks.
