Li 6 PS 5 X (X = Cl, Br, I) argyrodites possess high ionic conductivity but with rather scattered values due to various processing conditions. In this work, Li 6 PS 5 X solid electrolytes were prepared by solid-state sintering or mechanical alloying and optimized with or without excess Li 2 S. Solid-state sintering prefers excess Li 2 S, whereas mechanical alloying prefers stoichiometric Li 2 S to synthesize high-purity samples with high ionic conductivity. Solid-state sintering is also more suitable than mechanical milling for high ionic conductivity. Li 6 PS 5 Cl with the highest ionic conductivity among Li 6 PS 5 X was comprehensively characterized for electrochemical performance and air stability. MoS 2 /Li 6 PS 5 Cl all-solid-state batteries assembled with Li 6 PS 5 Cl-coated MoS 2 as cathode and with Li 6 PS 5 Cl as solid electrolyte demonstrate high capacity and good cycling stability.

Recently, highly abundant natural materials have been used in the fields of energy storage because of their environmental friendliness and low cost. However, use of some natural materials like cellulose as host matrices of gel polymer electrolytes (GPEs) is challenging owing to the strong intra- and inter-molecular hydrogen bonding. Herein, a green GPE film was prepared by chemically grafting soft chain-polyethylene glycol (PEG) onto the backbone of cellulose. The introduction of PEG significantly improved the toughness of cellulose from 118 × 10 3 to 270 × 10 3 kJ m −3 , as well as raised the wettability in carbonate-based liquid electrolyte solutions from 22.6% to 141.7%. The first cycle coulomb efficiency stayed above 90%. The capacity retention of LiFePO 4 /Li batteries assembled with the as-obtained GPE reached 80.3% after 300 cycles at 0.2 C. In sum, the as-obtained cellulose-based GPEs look promising to replace separators and liquid electrolytes in Li-ion batteries.

With high theoretical energy density and low cost, lithium‑sulfur batteries are viewed as next-generation energy storage technologies. But issues like the polysulfide shuttle effect and electrolyte safety concerns hinder their commercialization. Here, we present a novel cathode-supported black phosphorene modified composite polymer solid electrolyte membrane (CS-BP-CPSEM) made from polyethylene oxide-polyvinylidene fluoride polyblend and black phosphorene. Black phosphorene nanosheets, produced via electrochemically assisted liquid-phase exfoliation, are uniformly dispersed in the composite polymer matrix and directly multilayer tape-cast onto the cathode surface. This design improves interfacial contact and Li + transport. The optimized CS-BP-CPSEM with 0.3 wt% BP shows a 5.37 V electrochemical stability window and 1.3 × 10 −3 S cm −1 ionic conductivity at 60 °C. Polysulfide adsorption tests confirm black phosphorene's strong anchoring ability, effectively lessening the shuttle effect. Consequently, the assembled all solid-state lithium sulfur battery (ASSLSB) delivers a high discharge capacity of 1322 mAh g −1 and maintains 453 mAh g −1 after over 100 cycles at 0.05C. This work offers a promising interfacial engineering strategy using two-dimensional materials to boost high-energy-density and long-cycle-life solid-state Li-S battery development.

Innovatively developed an “adhesion-assisted growth” strategy for fabricating MOF membranes. • Constructed dual-confined ion channels enabling highly selective lithium-ion transport. • Implemented seed implantation in the adhesive layer to induce rapid and well-ordered MOF growth. • Established interconnected interface architecture forming continuous ion transport networks. • The developed membrane exhibits excellent long-term operational stability. Membranes featuring ordered biomimetic ion channels have been widely explored for ion-sieving applications, such as lithium extraction from salt-lake brines, seawater desalination, and energy conversion. However, achieving high ion permselectivity while enabling scalable fabrication for industrial use remains a major challenge. Here, we report a dual-confined metal-organic framework (MOF) membrane fabricated via an “adhesion-assisted growth” strategy. By integrating biomimetic ion channels functionalized with acidic groups, precise pore-size control, and surface chemical modulation, the membrane establishes a dual-nanoconfined separation system that simultaneously enables efficient Li + transport and effective Mg 2+ rejection. This specially designed adhesive layer not only promotes the well-defined formation of the MOF layer but also creates an interconnected ion transport network, thereby accelerating ion migration during selective electrodialysis (SED). Consequently, the resulting MOF membrane achieves a Li + flux of 1.17 mol·m −2 ·h −1 and exhibits a Li + /Mg 2+ permselectivity 14.3 times higher than that of the unmodified membrane, alongside excellent long-term operational stability. This environmentally friendly lithium extraction strategy advances the development of high-performance separation membranes and holds great promise for key applications such as lithium recovery from salt-lake brines, offering an innovative technological pathway toward efficient strategic resource recovery and the advancement of a circular economy. The synergistic dual-confined mechanism governs the selective Li + /Mg 2+ sieving performance of the MOF membrane. Download: Download high-res image (146KB) Download: Download full-size image

When CO 2 undergoes a two-electron partial reduction during the discharging process of Li-CO 2 batteries, it produces thermodynamically active Li 2 C 2 O 4 , which readily decomposes during subsequent charging. This offers a promising opportunity to mitigate the large charging overpotential and enhance the battery's cycling stability. However, as an intermediate, Li 2 C 2 O 4 tends to transform to the inert Li 2 CO 3 readily. In this work, we report a high-performance cathode catalyst featuring ultrasmall RuO 2 and BiOCl uniformly co-decorated on an MXene substrate (RuO 2 -BiOCl). It effectively stabilizes Li 2 C 2 O 4 during discharge, facilitating the two-electron partial reduction of CO 2 ; meanwhile, it can also modulate the morphology of discharge products, resulting in an intimate and extensive solid–solid interface between the insulating discharging product and the electrocatalyst. This together avoids accumulation of bulky, highly inertial and insulating Li 2 CO 3 in the cathode during cycling, which decreases the charging polarization and prolongs the Li-CO 2 battery life span. The optimal Li-CO 2 battery delivers a high discharge capacity of 10.33 mAh cm −2 during the first full cycle, and extraordinary durability, sustaining over 10 000 h of operation with a fixed areal capacity of 0.10 mAh cm −2 at 0.02 mA cm −2 . By tuning the CO 2 reduction path, this work offers a novel approach for building high-performance, practically workable Li-CO 2 batteries.

Ni-rich layered oxide LiNi0.91Co0.06Al0.03O2(NCA91) with high specific capacity has emerged as a leading cathode candidate for advanced lithium-ion batteries (LIBs). Nevertheless, increase in Ni content triggers structural instability and fast capacity degradation, which severely impedes the practical application of Ni-rich materials. Herein, a comprehensive study is conducted to explore the structural evolution and electrochemical behaviors of NCA91 cathodes with precisely tuned Li/TMs (transition metals) molar ratios spanning from 1.01 to 1.07. Results reveal that the NCA91 electrode with an optimal Li/TMs ratio of 1.03 exhibits outstanding structural integrity, coupled with remarkable cycling durability and rate capability. Specifically, the cathode with Li/TMs = 1.03 retains 88% of its initial capacity after 100 cycles at 1 C, and maintains ~130 mAh g−1even at 10 C. This work establishes a quantitative structure–composition–performance correlation that offers critical design principles for developing ultrahigh-nickel cathode materials.

As one of the highest-capacity commercial cathodes, lithium-rich manganese oxide (LMNO) currently faces challenges related to suboptimal structural stability and capacity retention. We find that this challenge is attributed to internal stress caused by limited grain growth and inherent lattice strain within LMNO. A simple and effective heat treatment strategy, combining Zr doping, is proposed to address these issues. Zr doping increases lattice spacing, alleviating the inherent lattice strain in the two-phase region. Thermal shock promotes atomic diffusion and grain boundary migration, reducing the number of grain boundaries and phase interfaces, thereby alleviating internal stress and facilitating grain growth. Finally, this design with reduced internal stress results in superior structural stability and cycle retention. After 200 cycles at 0.5C current density, the capacity retention of LMNO reaches 93.02%, with significantly suppressed voltage decay. This work underscores the importance of internal stress management in achieving highly stable cathode materials, offering new insights for the design and optimization of cathode materials.

Layered Li-rich manganese-based Li1.2Ni0.13Co0.13Mn0.54O2(LNCMO) is regarded as a promising high-capacity cathode material. However, its commercial application is severely hindered by rapid capacity fading, serious voltage decay and poor cycling stability. Herein, a facile non-sintering electrostatic adsorption strategy employing PDDA is proposed to fabricate a uniform and dense graphene oxide (GO) coating on LNCMO particles. Structural and morphological characterizations confirm the successful decoration of GO on the surface of LNCMO. The optimized 0.5@LNCMO sample delivers a discharge capacity of 330 mAh g−1at 0.1C, and maintains a capacity retention of 86.5% after 200 cycles at 1C and 83.3% after 400 cycles at 5C, showing much better electrochemical performance than pristine LNCMO. This study proves that the proposed strategy is an effective modification method for constructing high-performance Li-rich cathode materials.

Li/Te co-doped CaWO 4 ceramics with Li:Te molar ratios of 1:0.5, 1:0.75 and 1:1 was prepared to examine composition- and processing-dependent structural evolution and microwave dielectric properties. The Li:Te = 1:1 series was optimized at 890 °C, whereas the Li:Te = 1:0.5 and 1:0.75 series were optimized at 910 °C. XRD and Rietveld refinement, Raman spectroscopy, EPR, XPS, GCIB depth-profile XPS, ICP-OES and electron microscopy were used to correlate phase assemblage, local bonding, chemical-state signals, retained Li, microstructure and dielectric response. Under the respective optimized conditions, the Li:Te = 1:0.75, x = 0.04 ceramic exhibited the highest Q× f value of 89,613 GHz, while the Li:Te = 1:1, x = 0.04 ceramic showed the least negative τf value of −32.06 ppm/°C. GCIB depth-profile XPS revealed composition-dependent depth evolution of the relative Te 4 + - and Te 6+ -related signals, and ICP-OES confirmed systematic differences in total retained Li. In the Li:Te = 1:1 series, electron microscopy identified a Te/O-enriched amorphous interfacial region. Together, these results show that the Li:Te ratio and sintering condition jointly influence local structure, densification behaviour and microwave dielectric properties. The work provides a basis for optimizing the balance between low dielectric loss and temperature stability in CaWO 4 -based ceramics. Furthermore, a preliminary Ag co-firing test further indicates chemical compatibility under the tested condition.

As one class of important functional materials, lithium-rich layered oxides (LLO) are considered as promising cathodes for advanced Li-ion batteries due to their high theoretical specific capacity. Nonetheless, their practical applications are greatly hindered by the inferior rate capability and pronounced capacity and voltage decay under cycling conditions. In this work, the aniline is innovatively employed as an additive to fabricate LLO by controllable annealing treatment of the sol-gel precursor under an air atmosphere. Both experimental and theoretical analyses reveal that the introduction of aniline induces oxygen vacancies, effectively suppresses Li + /Ni 2+ cation mixing, consequently mitigating lattice oxygen release, enhancing Li + diffusion kinetics, and stabilizing the crystal structure. Consequently, the optimized aniline-modified sample (AMS-1) delivers high specific capacity and superior rate performance. Notably, ASM-1 can preserve 84.9% of its capacity after 400 cycles at 0.5C, exhibiting an average discharge voltage fade of merely 1.27 mV per cycle. This work offers a facile small-molecule-induced dual-functional integration strategy to elevate the cycling stability of LLO, which benefits from spurring the development of high-performance Li-rich cathode materials and advanced energy storage systems.

The application of metallic Li anodes as high-capacity anodes is usually compromised by unstable solid electrolyte interphase, Li0 dendrites, and side reactions, which lead to diminished cycling performance and serious safety concerns. To mitigate these issues, a hybrid single-ion-conducting protective layer (i.e., SPL-20) is proposed to enhance both the cycling lifetime and the safety of Li-metal batteries. With single-ion-conducting properties, such a layer can effectively reduce the uneven distribution of surface reactions, as evidenced by both simulations and electrochemical measurements. Thus, SPL-20 possesses the advantages of suppressing Li0 dendrites, preventing rapid capacity decay, and operability at extreme conditions (e.g., −25 °C). Notable achievements include an anode-free battery (LiFePO4/SPL-20@Cu cell) with a capacity retention of 59% at 0.5 mA cm–2 after 50 cycles, a LiFePO4/SPL-20@Li cell with a capacity of ∼110 mAh g–1 at 2C, especially a full cell with high-voltage cathode and 20 μm thick Li anode (NCM811/SPL-20@Li cell) with specific capacity of 172 mAh g–1 under 25 °C and 143.1 mAh g–1 under −25 °C after 100 cycles. This modified anodic interface strategy provides promising solutions to conquer interface challenges in high-performance Li-metal batteries.

Lepidolite, a critical mineral resource, contains lithium (Li), rubidium (Rb), and cesium (Cs) — indispensable core elements for modern industrial development. This study proposes a novel “calcining-electric field enhanced alkaline leaching” process for the simultaneous extraction of Li, Rb, and Cs from lepidolite. Under the calcination conditions (850 °C, 120 min) and optimal alkaline leaching parameters (70 wt% NaOH initial concentration, 4:1 liquid–solid ratio, 180 °C, 6 h, 100 r/min stirring speed, and 1.1 A/cm 2 current density), the leaching efficiencies of Li, Rb, and Cs reach 94.3%, 95.2%, and 92.6%, respectively. Compared with the traditional alkaline leaching without an electric field, the proposed method improves the leaching rates of Li, Rb, and Cs by 5.2%, 1.0%, and 11.3%, respectively, under the combined effects of external electric field and alkaline medium. Combined with phase analysis, micro-morphology characterization, surface element content determination, and reactive oxygen species (ROS) quantitative analysis via XRD, SEM, EDS, and UV–Vis characterizations, the core mechanism is revealed: the external electric field induces in-situ formation of stable ROS in the alkaline medium, which effectively destroys the surface and layered structure of calcined lepidolite concentrate, accelerates the oxidative decomposition of ionic bonds in polymetallic silicates and uniform substitution on the mineral surface, exacerbates lattice distortion and internal structure damage, promotes phase transformation of polymetallic silicates, and enhances the conversion of Li, Rb, and Cs to soluble hydroxides, ultimately realizing the directional phase reconstruction of lepidolite concentrate from primary aluminosilicate to soluble hydroxide phases.
