A slightly cross-linked lithium borate containing single ion-conducting polymer (LBSIP) as a bifunctional binder for lithium sulfur batteries is designed and fabricated via a one-step thiol–ene click reaction. The LBSIP binder exhibits a maximum peeling strength of over 600 mN mm–1 between the sulfur cathode and aluminum foil, together showing a high lithium ion diffusion coefficient of 2.1 × 10–12 cm2 s–1. Owing to the unique electron-donating groups, the binder can provide a good ionic conductive network and a dramatically enhanced polysulfide-trapping feature. The strong interaction between electron-donating groups of LBSIP with Li2S6 was confirmed by the 7Li-NMR analysis and density-functional theory calculation. The cathode using the LBSIP binder exhibited a high Coulombic efficiency of ∼100% and an initial specific capacity of 712 mAh g–1 with a capacity fading rate of 0.06% per cycle after 500 cycles at 0.5 C. Even at a high current rate of 2 C, a reversible capacity of over 500 mAh g–1 was still obtained. However, the capacity of the cathode using the PVDF binder decreased to 331 mAh g–1 after 180 cycles at 0.5 C. This work is very attractive for the rational design of functional binders for Li–S batteries with both ion-transporting and polysulfide-trapping features.

A novel layered zinc silicate/carbon composite was fabricated through carbon embedment into the interlayers of zinc silicate through a hydrothermal method. The interlayer space could be effectively tuned from 1.22 to 3.37 nm by controlling the amount of carbon precursors. Such a layered zinc silicate/carbon structure promoted the lithium ions and electron transportation within the nanostructures, while the reduced graphene oxide (RGO) network improved the conductivity between nanostructures. Such a 3-D carbon based conductive network improved zinc silicates’ lithium storage property. After 50 cycles, two composite samples with different carbon loadings showed 778 mA h/g and 704 mA h/g, respectively.

This study systematically investigated the enrichment behavior, occurrence modes, and speciation evolution of critical metals—indium (In), lithium (Li), gallium (Ga), and rare earth elements with yttrium (REY)—during the combustion of Ningxia coal. Simulated combustion experiments were conducted over a temperature range of 500–900 °C, coupled with sequential chemical extraction procedure (SCEP), X-ray diffraction (XRD), and thermodynamic modeling (FactSage). Results indicate that these metals are significantly enriched in the ash, with In exhibiting the highest enrichment ratio (up to 23.64). Mineral phase transformations—especially the formation of hematite, anhydrite, quartz, and amorphous glass—govern the redistribution of the metals. For In, the primary host shifts from metal oxides at lower temperatures to sulfate and quartz phases at higher temperatures, while Li and Ga remain predominantly associated with aluminosilicate glass and sulfate phases. REY migrate from metal oxide carriers toward sulfate and quartz phases as temperature increases. Thermodynamic predictions further confirm the predominance of solid phases such as In 2 O 3 , LiAlSi 4 O 10 , and Ga 2 O 3 under the investigated combustion conditions. These findings provide critical insights into optimizing the recovery of critical metals from coal fly ash, supporting its high-value utilization and sustainable resource strategies.

Electrodeposition of an aluminum coating is an effective approach for improving the corrosion resistance of LA103Z Mg-Li alloy. In this study, aluminum coatings were electrodeposited on LA103Z alloy from an AlCl 3 -Et 3 NHCl ionic liquid electrolyte with CeCl 3 as an additive. The effects of CeCl 3 concentration (1 mmol·L -1 ∼0.1 mol·L -1 ) on the morphology, composition, microstructure, and corrosion resistance of the coatings were systematically investigated. Results show that within the range of 1 mmol·L -1 ∼0.01 mol·L -1 , the coating grain structure became fine and uniform. As the concentration increased to 0.1 mol·L -1 , the Ce content in the coating rose, leading to surface cracks and increased roughness. At a cerium concentration of 5 mmol·L -1 , Ce in the coating is predominantly present as trace amounts of Ce 2 O 3 and CeO 2 . Polarization measurements conducted in a 3.5 % NaCl solution reveal a corrosion potential of -1.43 V and a corrosion current density of 34.88 μA·cm -2 .

The integration of lithium metal anodes with high-voltage LiMnxFeγPO4 (LMFP) cathodes is critical for advancing battery energy density, yet it is hindered by severe interfacial instability, particularly at elevated temperatures. This study presents dinitrile-ether (EGBE) as a molecularly engineered multifunctional additive that synergizes with a concentrated ether electrolyte to stabilize both electrode interfaces. Theoretical and experimental evidence confirms that EGBE promotes preferential anion decomposition, forming robust, inorganic-rich interphases on the cathode and anode. These interphases enable uniform lithium plating-stripping and enhance high-voltage resilience. Mechanistically, electron-withdrawing cyano groups (−CN), augmented by an adjacent ether oxygen, simultaneously elevate the reductive stability of nitrile moieties and fortify oxidative resistance via retained lone-pair electrons. This dual functionality addresses the inherent limitations of conventional nitriles and ethers. Furthermore, EGBE effectively chelates dissolved Mn3+ ions, reducing dissolution by 60%. The resultant interphases support highly reversible lithium deposition, with a Coulombic efficiency of 99.3%. In a 4.5 V Li||LMFP full cell, the EGBE-modulated electrolyte achieves 96% capacity retention after 800 cycles and sustains stable operation over 320 cycles at 70 °C, demonstrating exceptional thermoelectrochemical robustness. This work establishes a rational electrolyte design paradigm using tailored additives to enable high-performance lithium metal batteries under extreme conditions.

Poly(1,3-dioxolane) (PDOL)-based electrolytes are promising candidates for lithium–sulfur (Li–S) batteries due to their high ionic conductivity and low cost. However, their poor interfacial compatibility with lithium metal impedes the formation of a stable solid electrolyte interphase (SEI). This challenge is further exacerbated by the fact that conventional nitrate additives (e.g., LiNO3) inhibit 1,3-dioxolane (DOL) polymerization. Herein, we propose isosorbide dinitrate (ISDN), a covalent organic nitrate, as a multifunctional additive that not only promotes DOL polymerization but also enables the formation of an inorganic-rich hybrid SEI (Li3N and LiNxOy), as verified through X-ray photoelectron spectroscopy (XPS) analysis and theoretical calculations. The reinforced SEI enhances interfacial ion transport and mechanical robustness, thereby achieving uniform and dendrite-free lithium deposition. Density functional theory (DFT) calculations further reveal strong chemical interactions between ISDN and PDOL, which effectively enhance the adsorption of polysulfide onto PDOL to suppress the shuttle effect. Benefiting from these synergistic functions, Li|PDOL@ISDN|Li symmetric cells achieve stable cycling exceeding 1000 h without short-circuit failure. Quasi-solid-state Li–S batteries also demonstrate excellent cycling stability, with a capacity retention of 84.7% after 100 cycles at 0.2C. This work offers a promising strategy for designing high-performance solid-state Li–S batteries based on PDOL electrolytes.

Designing high-performance anode materials is highly required and significant for developing next-generation Li-ion batteries since currently available graphite-based anode can hardly meet the need of advanced battery systems. Here, we develop a Fe2O3 microcake growing with Cu0.75Co2.25O4 nanoflakes, forming a hierarchically micro-nanostructured Fe2O3@Cu0.75Co2.25O4 composite, which exhibits high electrothermal performance as Liion battery anode material. Hierarchical structure effectively prevents the deterioration of cycling performance caused by large volume-change during cycling, while the nanoflakes growing on microcakes facilitate transport of ions and electrons. The results show that the Fe2O3@Cu0.75Co2.25O4 microcakes-based anode displays a high and stable capacity of 1029 mAh g⁻¹ after 100 cycles at 0.2 A g⁻¹, and stable rateperformance is also achievable. Moreover, in-situ X-ray diffraction study indicates reversible phase conversion upon charge-discharge. Our findings provide a promising design of hierarchical microcake structure for developing high-performance energy-storage composites and their secondary batteries.

O 2 (0 ≤ x ≤ 0.08) cathode materials were successfully synthesized by a sol-gel method. X-ray diffraction and the refinement data indicate that all materials have typical α-NaFeO 2 structure with R -3 m space group, and the a -axis has almost no change, but there is a slight decrease in the c lattice parameter as well as the cell volume. Scanning electron microscopy and high resolution transmission electron microscopy prove that all the samples have uniform particle size of about 200–300 nm and smooth surface. The energy-dispersive X-ray spectroscopy mapping shows that aluminum has been homogeneously doped in the Li 1.2 Mn 0.56 Ni 0.16 Co 0.08 O 2 cathode material. The cyclic voltammetry and electrochemical impedance spectroscopy reveal that appropriate Al-doping contributes to the reversible lithium-ion insertion and extraction, and then reduces the electrochemical polarization and charge transfer resistance.

Li 2 ZnTi 3 O 8 (LZTO) has been highlighted as a promising active anode material for rechargeable lithium-ion batteries, but it suffers from a low high-rate capacity due to the sluggish Li-ion diffusion kinetics and inevitable consumption of Li + due to side reactions at the electrode/electrolyte interface. In this study, using Li 3 PO 4 as a lithium ion conductor and interface modifier, the crystal structure and electrochemical properties of LZTO are systematically studied and confirm that it is a faster lithium ion conductivity. Li 3 PO 4 not only accelerates Li-ion transport and increases diffusion paths, but also exhibits interfacial stability at high temperatures. Due to these advantages, the LZTO electrode containing the Li 3 PO 4 coating layer exhibits significantly improved electrochemical performance. The new Li 3 PO 4 coated LZTO electrode shows a large discharge specific capacity of 158.9 mAh g − 1 and a high capacity retention of 99% is obtained after 200 cycles at a rate of 5.0 A g − 1 and combined with cycle stability. Furthermore, the Li 3 PO 4 coated LZTO electrode also exhibits excellent low electrode polarization and high temperature long cycling performance for 500 cycles at temperatures up to 70 °C.

The high-temperature corrosion behavior of an AlN/Mo functionally graded material (FGM) under the Li/LiF-LiCl-LiBr vapor has been investigated. It is suggested that the Li vapor diffuses along the AlN and AlN/Mo grain boundaries and enters the interior of adjacent AlN grains, leading to the disintegration of AlN grains and subsequent failures. The 3D Mo networks are barely corroded, thus preventing cracking that may occur due to the inconsistent deformation inside the FGM. This work unravels the high-temperature corrosion mechanisms for the AlN/Mo FGM. Meanwhile, the operating temperature threshold for the liquid metal batteries employing Mo/AlN/Mo seals is determined to be ∼ 600 °C.

Through preparing the porous Zn-0.8Li scaffolds with 50–70 % porosity by using NaCl particles as pore-forming agents in the range of 150–350 µm and 350–550 µm with the infiltration casting method, the present study investigated the pore structure , mechanical properties and weight loss in simulated body fluids (SBF), and conducted the cellular activity and in vivo degradation experiments on porous Zn-0.8Li scaffolds before and after chitosan coating treatment. The results showed that the porous samples with small pore size had higher mechanical properties and lower degradation rate. However, with relatively higher average porosity and through-porosity, the porous samples with large pore size showed better pore connectivity, which provided channels for nutrient transport and promoted the lateral growth of internal tissues. In terms of cell experiments, chitosan coated Zn-0.8Li scaffolds with large pore size had better cell activity and adhesion. Since the coating of chitosan inhibited the release of Zn 2+ during the implantation of porous Zn-0.8Li scaffolds in vivo, it effectively promoted the growth of new bone tissue around the porous scaffolds, which provided an ideal microenvironment for the adhesion, proliferation and differentiation of MSCS. The results of this study demonstrated the great potential of chitosan coated porous biodegradable Zn-based scaffolds for bone tissue engineering.

Carbon materials with large exposed surfaces and heteroatom doping have great potential in suppressing the shuttle effect in Li–S batteries. In this study, crosslinked triazine frameworks were successfully utilized to synthesize heteroatom-doped carbon nanosheets utilizing g-C3N4 nanosheets as the hard template and porogen. Characterization studies show that the nanosheets were highly crinkled and interconnected with a large surface area (1060 m2 g−1) and pore volume (2.14 cm3 g−1), and with highly dispersed N, O and S. After coating them on commercial Celgard separators, batteries with the modified separators showed a low self-discharge and an improved rate performance even at 4 C. At 0.5 C, the initial discharge capacity was 1240 mA h g−1 with a capacity decay of 0.059% per cycle for over 1000 cycles. Moreover, excellent cycling performances at 2 C for 500 cycles were also achieved. The excellent performance can be attributed to the large surface area and porous structure of NOS-C, the superior wettability toward the electrolyte, enhanced Li+ diffusion, strong interactions between polysulfides and doped atoms, and the accelerated redox kinetics of polysulfides.
