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.

Rational hierarchical micellar gel electrolytes with synergistic hydrophobic-hydrophilic integration for dendrite-free zinc-ion batteries SCIE

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 :

In the quest to align with industrial benchmarks, a noteworthy gap remains in the field of electrochemical nitrogen fixation, particularly in achieving high Faradaic efficiency (FE) and yield. The electrocatalytic nitrogen fixation process faces considerable hurdles due to the difficulty in cleaving the highly stable NN triple bond. Additionally, the electrochemical pathway for nitrogen fixation is often compromised by the concurrent hydrogen evolution reaction (HER), which competes aggressively for electrons and active sites on the catalyst surface, thereby reducing the FE of nitrogen reduction reaction (NRR). To surmount these challenges, this study introduces an innovative bimetallic catalyst, CuGa2, synthesized through p-d orbital hybridization to selectively facilitate N2 electroreduction. This catalyst has demonstrated a remarkable NH3 yield of 9.82 mu g h-1 cm-2 and an associated FE of 38.25%. Our findings elucidate that the distinctive p-d hybridization interaction between Ga and Cu enhances NH3 selectivity by reducing the reaction energy barrier for hydrogenation and suppressing hydrogen evolution. This insight highlights the significance of p-d orbital hybridization in optimizing the electrocatalytic performance of CuGa2 for nitrogen fixation.

The leveraging ether C-H bond shielding strategy for antioxidative electrolyte in lithium-ion batteries SCIE

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.

Suppressing intergranular cracking with near-surface layer regulation for electrochemical-thermal stabilization of LiCoO2 SCIE

Abstract&Keyword Cite Version(2)

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 :

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 :

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&Keyword Cite Version(1)

Abstract :

An ideal solid-state electrolyte needs to combine the properties of high ionic conductivity, wide electrochemical stability window, high electrode-electrolyte chemical compatibility, and low cost. Composite solid-state electrolyte is one of the feasible ways to solve this problem. In this work, a composite solid-state electrolyte Li2ZnSiO4 (LZSO)/ LiAlCl4 is reported. The low melting-point LiAlCl4 is introduced to solve the interfacial impedance problem of LZSO solid-state electrolyte due to the hardness of the particles. The structure and electrochemical properties of the two compositions were also characterized, and the effects of different composite ratios on the ionic conductivity of the composite solid-state electrolyte and the low-temperature healing surface structure on the performance enhancement were investigated. The optimal ratio LZSO/LiAlCl4 (7:3) exhibits good interfacial contactness and an ionic conductivity of 1.65 x 10(-4) S cm(-1) at 60 degrees C as well as a low activation energy of 0.31 eV. The assembled lithium symmetric batteries were stably cycled up to 750 h. Compared with the single component of LZSO, which cannot satisfy the full-cell assembly, Li/LFP batteries assembled with composite solid-state electrolytes exhibit good cycling performance.

Abstract&Keyword Cite Version(2)

Abstract :

To meet the demand for higher energy density in lithium-ion batteries, extensive research has focused on advanced cathodes and metallic lithium anodes. However, Ni-rich cathodes suffer from the inactive phase- transition and side reactions at the cathode-electrolyte interfaces (CEI). In this study, we propose a novel approach to enhance the solubility of LiNO3 3 in carbonate electrolyte systems using a local high-concentrated addition strategy with triethyl phosphate as a co-solvent. Rather than the traditional solvent-dominated solvation clusters, the NO3- dominated electrolyte is examined to elucidate unique complexation phenomena. Two distinct clusters in NO3- dominated electrolyte arising from as a consequence of intramolecular interactions intrinsic to the constituents. This promotes the formation of a homogeneous oxynitride interphase and facilitates more expeditious lithium ion diffusion kinetics. Hence, the less stress fragmentation and irreversible phase transformation occur on the cathode surface with the homogeneous oxynitridation interface. This innovative design enables efficient cycling of the Li || NCM811 cell, offering a promising strategy to improve lithium-ion batteries performance.

Abstract&Keyword Cite Version(2)

Abstract :

Studying lithium growth on diverse substrates with unique crystal structures is crucial for linking atomic and macroscopic views, which ensures a long cycle life and safety in lithium metal batteries. This work provides explanations on (1) the stages of nucleation, which are influenced by the adsorption-relaxation mechanism, (2) acquiring evolved traits of dendritic morphology from the embryo, and (3) the integration of the atomic and macroscopic perspectives through a variety of techniques at different scales to validate dendrite evolution. The heteroepitaxial growth process of the embryos is divided into two principal stages: nucleation and growth. The adsorption-type substrates exhibit characteristics of relatively lower average interaction energy and specific stress energy during the nucleation stage. At the growth stage, the adsorption-type substrate tends to facilitate multilayer growth. This work provides potential to design and material selection for lithium metal batteries, contributing to the development of safer, more efficient, and longer-lasting energy storage systems.
