Spatially decoupled fluorinated-ether-ester electrolytes for extreme-condition lithium metal batteries SCIE
期刊论文 | 2025 | MATERIALS HORIZONS
Abstract&Keyword Cite

Abstract :

Traditional ether-based electrolytes of Lithium metal batteries (LMBs), while enabling stable lithium deposition and low-temperature operation, suffer from insufficient oxidative stability under extreme conditions. Here, we propose a spatially decoupled solvation-shell strategy to construct weakly oriented fluorinated-ether-ester hybrid electrolytes with outer-shell fluorination protection. A spatially decoupled solvation structure is constructed where ether dominates the inner shell for stable Li+ coordination, while fluorinated solvents form an oxidation-resistant outer shield. The long-chain anion-coordinated cluster complexes redirect decomposition pathways, enriching both anode and cathode interfaces with LiF and Li3N, enhancing interfacial stability and Li+ transport. Fluorine-induced interactions disrupt solvent ordering, while fluorinated CEI/SEI layers mitigate dendrite growth and cathode degradation. The Li||LiNi0.8Co0.1Mn0.1O2 full cell retains 85.2% capacity after 100 cycles at -20 degrees C and 4.5 V. The work establishes a spatially decoupled solvation-shell paradigm for simultaneously addressing thermodynamic and kinetic challenges in extreme-condition energy storage systems.

Abstract :

The influence of hydrogen bonding on spectroscopic properties is one of the fundamental issues in the field of luminescent organic-inorganic hybrid metal halides (OIMHs). We design and prepare three OIMHs, namely, crystals 1, 2 and 3, using 2,2 '-bipyridine and ZnCl2 as starting materials. From crystals 1 to 3, the hydrogen bonding environment surrounding the 2,2 '-bipyridinium cations gradually weakens, with both the dihedral angle and the number of hydrogen bonds around them decreasing progressively. Correspondingly, the blue emission belonging to the S1 -> S0 transition of the three crystals gradually increases, with crystal 3 exhibiting the strongest blue light emission and a photo-luminescence quantum yield reaching 34.10%. In crystal 1, the dense hydrogen bonding environment of the 2,2 '-bipyridinium cation results in an obvious energy transfer from S1 to T1. This reduces the population of the S1 state, thereby leading to weaker blue light emission. In crystals 2 and 3, the weaker hydrogen bonding environment and smaller spatial distortion of organic cations weaken or even prevent energy transfer between S1 and T1, thereby enhancing blue light emission. These findings provide new insights for exploring novel luminescent OIMHs and developing more effective means of regulating their luminescence performance.

Abstract :

Halide solid electrolytes receive much attention due to their electrochemical properties, such as high ionic conductivity, oxidative stability, and ease of preparation. In this work, a bromide solid electrolyte LiBiBr4, exhibiting ease of processing and high ionic conductivity, is designed for the first time and investigated through a comparative investigation with monoclinic LiAlCl4 and LiAlBr4 for the migration path. The processing pressure for LiBiBr4 with annealing at 120 degrees C is less than one-tenth that of other chloride electrolytes (approximate to 5 MPa). Computational analyses unveil crucial mechanistic insights into the three migration mechanisms and the factors that influence them within the monoclinic structure. The distribution and distance of non-Li polyhedrons to the migration pathways are pivotal for the migration. The strategic positioning of the Bi polyhedron in LiBiBr4 is far from the Li+ pathway. The unique leap migration within the LiBiBr4 has a lower energy barrier and facilitates an interconnected migration that forms a 3D interstice network. This interconnected leap migration network within LiBiBr4 constitutes a Z-type interstice leap migration along the ab-axis. Thus, the LiBiBr4 obtains a high ionic conductivity of 0.19 mS cm(-1) with the 0.349 eV low activation energy. This discovery and research methods provide significant impetus and support for the development of halogen-based electrolytes.

Aerobic oxidation of a covalent organic framework facilitating photocatalytic CO2 reduction with water SCIE

Abstract&Keyword Cite Version(2)

Abstract :

Photocatalytic CO2 reduction offers a promising approach for solar-to-chemical energy conversion. Achieving CO2 reduction under an aerobic environment is challenging, primarily owing to the competitive O2 reduction reaction at metal active sites. Herein, we demonstrate a hybrid photocatalyst of N3-COF/MoS2, where an azine-linked COF serves as a metal-free active site for CO2 reduction. The hybrid exhibits enhanced catalytic performance in CO2 reduction under aerobic conditions. At 20% O2 concentration, close to the atmospheric O2 content, the CO production rate reaches 28 mu mol g-1 h-1, which is much higher than that obtained using pure CO2. Structural, in situ spectroscopic and computational analyses reveal that the oxidation of azine groups in the COF by O2 induces the formation of highly active radical intermediates, which can suitably and preferentially react with CO2, resulting in the enhanced CO2 reduction performance in the presence of O2. This work provides a fresh insight into designing photocatalysts applied under ambient conditions for solar energy conversion.

Abstract :

Given the limited reserves and high cost of lithium resources, research into cost-effective, high-performance energy storage devices beyond lithium-ion batteries has gained increasing attention. Sodium metal anodes, with their abundant reserves, low cost, high specific capacity (1160 mA h g-1), and low redox potential (-2.714 V vs. the Standard Hydrogen Electrode (SHE)), are considered one of the most promising next-generation anode materials. However, the unstable solid electrolyte interphase (SEI) in sodium metal anodes leads to non-uniform diffusion and deposition of Na+, resulting in uncontrollable dendrite growth. During repeated charging/discharging processes, the growth of dendrites and the continuous fracture and regeneration of the SEI layer lead to the continuous loss of active sodium and coulombic efficiency (CE). To address this issue, this study reports an in situ generated organic/inorganic hybrid multifunctional solid electrolyte interface to effectively enhance the stability of the sodium metal anode. The inorganic components, NaF and Na2S, serve as high ionic conductivity components, accelerating the transfer of Na+. The rich amide groups in the organic component exert a polar attraction to Na+, regulating the Na+ flux and alleviating the "tip effect" during metal deposition. Experiments show that the Na & Vert;Na symmetric battery using this anode exhibits extremely low overpotential and stable plating/stripping behavior (cycling for over 2500 hours at 1 mA cm-2 and 1 mA h cm-2, with an ultra-low voltage of 15 mV). The full cell assembled with Na3V2(PO4)3 (NVP) demonstrates excellent rate and cycling performance, with a capacity retention rate of 90.3% after 1000 cycles at 1C and 89.2% after 800 cycles at a high rate of 5C.

Abstract :

To further meet the application needs of lithium-ion batteries, developing cathodes with higher voltage and higher operating temperatures has become a primary goal. However, LiCoO2 cathodes encounter structural issues, particle fracture, and side reactions during high-voltage and high-temperature cycling. Thus, this work designs a novel interface engineering approach involving near-surface Li layer regulation and enhances the stability of the R3m layered structure, suppressing intergranular cracking. An undistorted surface with reduced phase transitions was revealed by the HAADF-STEM. The interface regulation by post-cycle simulations and XRD stabilizes interplanar spacing. The strong B-O bonds lower the O 2p energies, preventing oxygen loss and side reactions confirmed by XPS and band structure. Therefore, even under 50 degrees C, the half-cell maintains a capacity retention rate of 79% after 200 cycles at 5C at 4.5 V.

Abstract :

Zinc-ion batteries (ZIBs) have promising prospects in energy storage field, but the water molecules in aqueous electrolytes significantly compromise the stability of the anode and cathode interfaces and hinder the low-temperature performance. Herein, water-in-oil type M & ouml;bius polarity topological solvation composed of oil, water, and amphiphilic salt are first-ever pioneered, forming the surfactant-free microemulsion electrolyte (SFMEE). This water-in-oil type M & ouml;bius solvation structure, characterized by its distinct inner and outer layers and a polarity inversion feature, successfully connects the non-polar phase with the polar phase, eliminating the need for surfactants to reduce costs and system complexity. The amphiphilic anion of salt creates a polarity singularity and stabilizes the polarity-reversed encapsulation. The outer oil layer disrupts the cohesive polarity network of water and constructs a polarity-reversed cage to restrict water. A series of SFMEE combinations are investigated and then directly applied to ZIBs, confirming excellent universality and durability of this design. The Zn||NVO (NaV3O81.5H(2)O) cells using SFMEE can stably cycle for 4000 cycles with a capacity of 125 mAh g-1 and 86.8% capacity retention. This discovery of M & ouml;bius solvation structure unlock unprecedented levels of electrolyte design and illuminate the development of next-generation high-performance energy storage systems.

Abstract :

Ether-based electrolytes exhibit low antioxidative properties (<4.2 V), significantly limiting their application in high-voltage cathodes. To address this gap, this study presents the leveraging ether C-H bond shielding (LEBS) strategy, an efficient approach to enhance the antioxidative properties of ether molecules through minimal functionalization. We selected a series of features related to conjugation effects, induction effects, and the molecular structure, using the change in carbon-hydrogen bond dissociation energy as the target value. Among the factors determining the antioxidative properties of ether molecules, the conjugation effect is dominant (89.72%) and negatively correlated with antioxidative properties. Therefore, weakening the stabilizing effect of the conjugation effect on ether carbon radicals is a crucial strategy for enhancing the antioxidative properties. The LEBS strategy categorizes ether molecules into symmetric and asymmetric types and classifies the functional groups on ether molecules to provide theoretical guidance for the modification scheme.

Abstract&Keyword Cite Version(2)

Abstract :

The uncontrolled dendritic growth and severe side reactions significantly constrain zinc-ion batteries' further application. This study presents a novel micellar gel electrolyte, innovatively designed through hydrophobic association. The micellar gel electrolyte harmonizes macroscopic and microscopic properties through a rational hierarchical design. At the macroscopic level, the hydrophilic domains as water-absorbing nets and the hydrophobic domains as pillars are intricately interwoven. On the microscopic scale, the copolymerization resulted in a microphase-separated architecture, with hydrophilic and hydrophobic domains establishing distinct micro-regions within the gel matrix. The hydrophilic domains contribute to the stabilization of the hydrogen bond network through amide groups, while the abundant carbonyl groups optimize the solvation structure and migration pathways of Zn2+. The hydrophobic domains provide a robust supporting framework while simultaneously reducing H2O activity and thereby minimizing parasitic reactions. Thus, the enhanced interfacial stability forms a robust and flexible barrier against dendrite formation. The rational hierarchical gel composition and cross-linked network effectively direct Zn deposition preferentially along the (002) plane, ensuring a uniform and stable interface. The assembled Zn & Vert;MnO2 batteries show 80% capacity retention after 1200 cycles at 1C.

Abstract :

Exploring the intercalation mechanism of the cathode during electrochemical processes is significance for the development of aqueous zinc-ion batteries. In this work, the H/Zn co-intercalation and the Zn intercalation mechanisms in VO2(B) cathode is systemically studied. By utilizing visualized characterization techniques such as TOF-SIMS, AC-TEM, in-situ XRD and XAFS with ab initio molecular dynamics, comprehensively elucidated three inherent drawbacks of the H+/Zn2+ co-intercalation from three perspectives: channel evolution, lattice transformation, and interface modification: 1) H+ intercalation obstructs Zn2+ migration channels, impairing Zn2+ mobility and resulting in difficult intercalation/extraction. 2) H+/Zn2+ co-intercalation induces excessive lattice expansion that ultimately leads to irreversible structural collapse. 3) H+ presence triggers irreversible byproduct formation, causing progressive interface degradation. Furthermore, we demonstrated that the sole Zn2+ intercalation mechanism avoids these critical flaws, highlighting its superior cycling performance. These findings elucidate the reasons for the rapid performance degradation of batteries in aqueous electrolytes, revealing the accurate reaction mechanism of the cathode and designing high-performance aqueous zinc-ion batteries in the future.
