All-solid-state lithium metal batteries offer high energy density and enhanced safety, yet mechanical instability at both positive electrode/solid electrolyte and Li metal/solid electrolyte interfaces severely limits cycling stability and rate performance, particularly at a low stacking pressure. Here, we report a facile, industry-compatible strategy to refine polycrystalline Li 5.5 PS 4.5 Cl 1.5 grains using Al 4 C 3 abrasives. The resulting Al 4 C 3 -engineered Li 5.5 PS 4.5 Cl 1.5 exhibits reduced average particle size and a narrowed size distribution. The refined electrolyte grains enable a high relative density in both anolytes and composite positive electrodes. Beyond particle refinement, Al 4 C 3 in the anolyte stabilizes the Li/electrolyte interface through its high modulus, low electronic conductivity, and favorable interfacial mechanics, enabling a high critical current density/capacity of 3.2 mA cm ‒2 /3.2 mAh cm −2 . Leveraging our designed electrolyte as both anolyte and catholyte, the all-solid-state lithium metal batteries demonstrate stable cycling performance under a low stack pressure of 4 MPa and a positive electrode loading of 1.4 mAh cm −2 , sustaining over 1500 cycles at 1.4 mA cm ‒2 . This study provides a potentially simple and scalable approach to optimize solid electrolyte particles and interfacial mechanics.

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.

Photo-assisted lithium‑carbon dioxide battery (Li-CO 2 ) can utilize the charge carriers generated at the cathode by light to reduce the kinetic barriers of carbon dioxide reduction and lithium carbonate decomposition reactions. However, rapid recombination of photogenerated carriers and sluggish interfacial charge transfer still lead to high overpotentials and limited cycle life in photo-assisted Li-CO 2 batteries. Therefore, it is crucial to design highly efficient photocatalysts that can suppress carrier recombination and accelerate interfacial charge transfer for rational optimization. Herein, we adopted the design strategy of metal ion doping and synthesized a Fe-doped ZnS (Zn 1-x Fe x S, denoted as ZFS-x) photocathode by the hydrothermal synthesis method. The doping of iron ions effectively regulates the electronic structure of ZnS, inhibits the recombination of photogenerated carriers, and accelerates the interfacial charge transfer kinetics. The photo-assisted ZFS-x cathode delivers a markedly prolonged cycling lifetime of up to 300 cycles (600 h) at a current density of 0.01 mA cm −2 , substantially exceeding that achieved under dark conditions (144 h). Furthermore, the single-cycle overpotential is significantly reduced from 2.27 V in the dark to 0.49 V under illumination. Morphology studies confirm that appropriate Fe-ion doping significantly enhances the uniformity of the discharge products, which are present as uniformly dispersed nanoscale particles rather than densely packed plate-like or aggregated structures. Moreover, their highly reversible decomposition during charging effectively mitigates pore blockage and interfacial passivation. These results indicate that the incorporation of iron can improve charge separation and regulate the formation and decomposition of Li 2 CO 3 , thereby effectively modulating the ZnS photocathode and ultimately enabling the development of photo-assisted Li-CO 2 batteries with low overpotential and long cycle life.

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.

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.

In this study, Li x Ca 1−x W 1−0.75x Te 0.75x O 4 ceramics were synthesised using a non-stoichiometric co-doping strategy (Li/Te = 1:0.75), systematically revealing the synergistic effect of Li and Te. During doping, Li was introduced from the decomposed secondary Li 2 TeO 4 phase, which acted as a liquid-phase sintering aid. Density functional theory calculations confirmed that Te 4+ substitution for W 6+ enhanced the chemical bond strength and effectively passivated oxygen vacancies, promoting densification and improving dielectric properties. However, excessive doping led to the substantial decomposition/volatilisation of the secondary phase, where the volatilisation of Te outweighed its positive substitution effect, thereby degrading both structure and dielectric performance. Following optimisation, the Li 0.04 Ca 0.96 W 0.97 Te 0.03 O 4 ceramic sintered at 910°C exhibited optimal properties: εr = 9.86, Q× f = 89,613, τ f = −38.6 ppm/°C. The material also exhibited favorable dielectric characteristics in the terahertz range (0.2–1.2 THz, ε r : 4.97–6.36, tan δ: 0.009–0.0848), rendering it a potential candidate for dual-band applications in low-temperature co-fired ceramic technology.

Lithium-sulfur batteries with high theoretical energy density have drawn much attention during the past decades, while the shuttle effect of the polysulfide also hinders the practical application. The employment of suitable host materials has been considered as the effective strategy to inhibit the polysulfide migration. In this work, we develop MoO 2 /C composite as sulfur host material to increase the capacity of lithium-sulfur batteries while retaining high capacity after cycles. The MoO 2 /C composite could serves as active sites, effectively adsorbing and catalytically converting polysulfide, thus improving the redox kinetics and reducing shuttle effect. Owing to these merits, the as-prepared MoO 2 /C@S cathodes exhibit high capacity of 1165 mAh g −1 at 0.1 C. Meanwhile, the battery exhibits superior rate capability and stable cycling performance.

Free-standing activated carbon nanofibers (ACNF) were prepared through electrospinning combining with CO2 activation and then used for nonaqueous Li–O2 battery cathodes. As-prepared ACNF based cathode was loosely packed with carbon nanofibers complicatedly overlapped. Owing to some micrometer-sized pores between individual nanofibers, relatively high permeability of O2 across the cathode becomes feasible. Meanwhile, the mesopores introduced by CO2 activation act as additional nucleation sites for Li2O2 formation, leading to an increase in the density of Li2O2 particles along with a size decrease of the individual particles, and therefore, flake-like Li2O2 are preferentially formed. In addition, the free-standing structure of ACNF cathode eliminates the side reactions about PVDF. As a result, the Li–O2 batteries with ACNF cathodes showed increased discharge capacities, reduced overpotentials, and longer cycle life in the case of full discharge and charge operation. This provides a novel pathway for the design of cathodes for Li–O2 battery.

Graphical Dual ion storage : A high-performance and ultralong-life Mg−Li hybrid battery is presented, with the cobalt-doped anatase (Ti 1- x Co x O 2- y ) nanosheet cathode exhibiting outstanding pseudocapacitance. In-situ X-ray diffraction measurements reveal the unique Mg−Li dual-ion storage mechanism. This tactic presents new opportunities to design advanced Mg−Li hybrid batteries. Despite the proposed safety, performance, and cost advantages, practical implementation of Mg−Li hybrid batteries is limited due to the unavailability of reliable cathodes compatible with the dual-ion system. Herein, a high-performance Mg−Li dual ion battery based upon cobalt-doped TiO 2 cathode was developed. Extremely pseudocapacitance-type Ti 1- x Co x O 2- y nanosheets consist of an optimum 3.57 % Co-atoms. This defective cathode delivered exceptional pseudocapacitance (maximum of 93 %), specific capacities (386 mAh g −1 at 25 mA g −1 ), rate performance (191 mAh g −1 at 1 A g −1 ), cyclability (3000 cycles at 1 A g −1 ), and coulombic efficiency (≈100 %) and fast charging (≈11 min). This performance was superior to the TiO 2 -based Mg−Li dual-ion battery cathodes reported earlier. Mechanistic studies revealed dual-ion intercalation pseudocapacitance with negligible structural changes. Excellent electrochemical performance of the cation-doped TiO 2 cathode was credited to the rapid pseudocapacitance-type Mg/Li-ion diffusion through the disorder generated by lattice distortions and oxygen vacancies. Ultrathin nature, large surface area, 2D morphology, and mesoporosity also contributed as secondary factors facilitating superior electrode-electrolyte interfacial kinetics. The demonstrated method of pseudocapacitance-type Mg−Li dual-ion intercalation by introducing lattice distortions/oxygen vacancies through selective doping can be utilized for the development of several other potential electrodes for high-performance Mg−Li dual-ion batteries.

Li/garnet/LiFePO 4 solid-state battery was fabricated. The cathode contains LiFePO 4 , Ketjen black, poly(vinylidene fluoride):LiTFSI polymer as active material, electric conductor and Li-ion conducting binder, respectively. Polyvinylpyrrolidone was added into the cathode to improve cathode/electrolyte interfacial performance. When combined with polyvinylpyrrolidone additive, poly(vinylidene fluoride):polyvinylpyrrol idone:LiTFSI blend forms, and the cathode/electrolyte interfacial resistance reduces from 10.7 kΩ to 3.2 kΩ. The Li/garnet/LiFePO 4 solid-state battery shows 80% capacity retention after 100 cycles at 30 °C and 0.05 C. This study offers a general strategy to improve cathode/electrolyte interfacial performance and may enable the practical application of solid-state Li-metal batteries.
