However, the catalyst reconstruction mechanism is still ambiguous, and the influence of interfacial hydrogen bond on NO3−RR performance remains unexplored. Herein, a Cr doping strategy is developed to regulate interfacial hydrogen-bonded interactions on the Co-based dynamic electrocatalyst for improving electrocatalytic NO3−RR activity. In-situ XRD, in-situ Raman and theoretical calculations indicate that doping Cr can modulate the reconstruction process of the Co-based material, achieving the dynamic balance of Co(OH)2 and Co. Moreover, molecular dynamics simulations, density functional theory calculations combined with in-situ infrared spectra reveal that strong hydrogen-bonded interactions between interfacial H2O and the Cr doped Co(OH)2 surface can drag more free H2O from rigid H2O network and facilitate the H2O dissociation with the formation of active hydrogen for accelerating the NO3−RR pathway on metallic Co site. As a result, the Cr doped Co-based dynamic electrocatalyst can display a superior NH3 Faradaic efficiency of 97.36% and a high NH3 yield rate of 58.92 mg h-1 cm-2, outperforming the state-of-art electrocatalysts. This work can further inspire the dynamic electrocatalyst design and interfacial microenvironment modulation for electrochemical hydrogenation reactions.","PeriodicalId":72,"journal":{"name":"Energy & Environmental Science","volume":"25 1","pages":""},"PeriodicalIF":32.5,"publicationDate":"2025-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143819130","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the influence of [p] and VSn-2 on their ionic transport properties remains elusive. Herein, the link between electronic and ionic transport is unravelled in a compendium of Sn-based perovskite compositions. Specifically, ionic and electronic conductivities are found to concomitantly rise with higher Sn content. Using a combination of electrical characterization techniques, a rise in [p] and VSn-2 is demonstrated to increase mobile ion density, enhancing lateral ion migration and ionic conductivity. First-principles simulations reveal that [p] and VSn-2 jointly lower the energy barrier for iodide migration from 0.38 eV to 0.12 eV. Chemical mapping techniques support these observations by identifying the bias-induced migration of iodide and formamidinium ions in compositions with higher [p] and VSn-2.

However, electrolytes containing fluorine present adverse environmental risks due to their high greenhouse gas emissions and caution of global warming. Hence, developing fluorine-free alternatives is imperative to design net-zero fluorine electrolytes. This review addresses the need for sustainable, low-toxicity electrolytes by exploring strategies for eliminating fluorine in the electrolytes system. Studies on the choice of electrolyte ingredients, such as fluorine-free salts, green solvents, safe additives, and fluorine-free binders, effectively enhance battery performance and safety. Recent progress highlights significant improvements in the environmental impact and functionality of fluorine-free electrolytes (FFEs), demonstrating their potential for practical applications. Despite these advancements, challenges remain in matching the performance and stability of traditional fluorinated electrolytes. Future research encourages to focus on developing fluorine-free materials, understanding functional degradation processes, and ensuring commercial scalability. This review provides an in-depth look at recent innovations and promotes design principles for complete fluorine elimination strategies. It guides future pathways for creating high-performance, non-flammable, low-cost, environmentally sustainable FFEs for advanced rechargeable batteries.

Their applications, however, have been limited by the sluggish Zn2+ transfer kinetics, severe polyiodide shuttling, and relatively low mass loading of iodine cathodes. Herein, we report a design strategy for a quasi-solid-state Zn–I₂ battery with a continuous 3D ion-transport network by integrating a thick iodine cathode and a bacterial cellulose hydrogel electrolyte. The polar bacterial cellulose fibers formed an interconnected network that provided abundant ion pathways for inward Zn2+ transport and also limited iodine species dissolution. The continuous 3D ion-transport networks were formed throughout the entire thick iodine cathode, resulting in a 10-times higher Zn-ion conductivity compared with the conventional-structured cathode. The quasi-solid-state Zn–I2 battery based on the Zn anode and an integrated cathode delivered a reversible capacity of 176.6 mAh g−1 and achieved long-term cycling for 900 cycles at 1 C under a iodine loading of 20.0 mg cm−2. The iodine loading can be further increased to 39.3 mg cm−2 by adjusting the thickness of cathode. Under a practical condition of low negative/positive ratio (N/P) of 2.1, an energy density of 56.4 Wh kg−1 is achieved. This integrated electrode design provides guidelines for fabricating high-energy quasi-solid-state Zn ion batteries.","PeriodicalId":72,"journal":{"name":"Energy & Environmental Science","volume":"18 1","pages":""},"PeriodicalIF":32.5,"publicationDate":"2025-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143813797","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This insight regarding the importance of galvanic corrosion is enabled by the combination of machine learning with rigorous experimental characterization. First, we partition our electrolyte data into low and high Coulombic efficiency (CE) segments to obtain an interpretable machine learning model which informs the design of high-performing (high CE) electrolytes. We design new model-guided, high-performing electrolytes and use spectroscopy and electroanalytical methods to demonstrate the weak correlation between common design metrics and performance in the high-performing electrolytes.

Here we design a thiazole-linked covalent organic frameworks (TZ-COFs) hosted organic trimethylsulfonium iodide (C3H9IS/TZ-COFs) electrode in 1-methyl-3-propylimidazolium bromide (MPIBr)-containing electrolyte to stimulate I−/I0/I+/I5+ iodine conversion chemistry with better electrochemical efficiency and stability. Compared with inorganic symmetric I2 molecules, the more easily exposed I− center of polar C3H9IS combines with the oxygen in H2O to form HIO3, which initiates 6 e− I−/IO3− conversion through I+ activation of MPIBr, thus reducing the oxidation/reduction potential gap to achieve 97% iodine conversion efficiency. Meanwhile, thiazole units of TZ-COFs enable strong chemical adsorption with IO3− species to improve redox stability with high reversibility due to reduced energy barriers (−5.1 vs. −3.5 eV in activated carbon (AC) host) and upgraded conversion kinetics (activation energy: 0.21 vs. 0.38 eV in AC).

In the current study, two dopants known to have different site occupancies in Ni-rich layered cathodes, Mg and W, are revisited, revealing the relationship between dopant-induced local structure changes and electrochemical reversibility across a broad charge/discharge voltage range. Our results indicate that the introduced W induces Li-W-Li medium-range order (MRO), resulting in a lower electron concentration in O 2p orbitals. The MRO in a W-doped Ni-rich layered oxide (LNCW) triggers asymmetry in the NiO6 octahedra and weakens the surrounding hybridization, leading to a highly covalent Ni4+-O bond and activating charge transfer from the ligand. Although the contribution of oxygen oxidation was somewhat reduced in LNCW, the distorted NiO6 octahedra arising from deepened cationic oxidation worsened the electrochemical performance significantly. By contrast, Mg occupies the 3b site of Li and thereby forms MgO4 tetrahedra, inducing Ni-Mg-Ni MRO and a resulting charge redistribution that shrinks the Ni 3d orbital band, leading to a reversible Ni-redox process and suppressing oxygen oxidation. Hence, the Mg-doped Ni-rich layered oxide (LNCMg) maintains superior structural integrity to LNCW, avoiding the parasitic distortion of NiO6 octahedra and alleviating the chemo-mechanical heterogeneity. This work underscores the significance of medium-range order in the chemo-mechanical interplay in Ni-rich layered cathodes.","PeriodicalId":72,"journal":{"name":"Energy & Environmental Science","volume":"108 1","pages":""},"PeriodicalIF":32.5,"publicationDate":"2025-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143806450","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
