Achieving a reversible four-electron-per-oxygen-molecule oxygen evolution reaction is an essential yet highly challenging task for nonaqueous lithium hydroxide-based Li | |O 2 batteries, as the kinetically sluggish oxygen evolution reaction tends to entangle with competing parasitic reactions, whose origins and mitigating strategies remain largely elusive. Here we construct a highly reversible lithium hydroxide-based Li | |O 2 battery using iron–cobalt–nickel layered double hydroxide catalysts and tetramethylene sulfone-based electrolytes. Lithium hydroxide decomposition toward oxygen evolution involves key reactive oxygen species of surface-bound hydroxyl and hydroxyl radicals, but no singlet oxygen. These hydroxyl species corrode the electrolyte and carbon support, predominantly accounting for charging irreversibility. While oxidation-resistant solvents and electrical conductors are necessary to reduce hydroxyl-induced side reactions, the synergistic interplay of interfacial water solvation and catalytic surface structures hold the key to steering hydroxyl activity toward the desirable oxygen evolution reaction or by-product formation. This work offers insights into achieving long-life lithium hydroxide-based Li | |O 2 batteries.

Fast-charging graphite-based lithium-ion batteries (LIBs) are limited by sluggish Li+desolvation, interfacial charge transfer, and solid-state diffusion in graphite (Gr). Herein, a salt-concentration-regulated lithium bis(trifluoromethanesulfonyl)imide (LiTFSI) in 1,3-dioxolane (DOL) and fluoroethylene carbonate (FEC) electrolyte is developed to construct an anion-involved solvation structure for fast-charging graphite-based LIBs. At an appropriate LiTFSI concentration, TFSI−is incorporated into the primary Li+solvation sheath, forming a contact-ion-pair (CIP)-dominated solvation structure. The optimized electrolyte exhibits a Li+transference number of 0.76 and an exchange current density of 0.28 mA cm−2, indicating accelerated Li+transport and interfacial charge transfer. Furthermore, a more uniform interfacial Li+flux distribution is obtained, contributing to suppressed localized Li growth. As a result, Gr||Li half cells deliver 168 mAh g−1at 10 C (1 C = 370 mAh g−1). LFP||Gr full cells with an LiFePO4(LFP) areal capacity of 4 mAh cm−2deliver 115 mAh g−1at 2 C and retain 69% capacity after 200 cycles. This work highlights moderate salt-concentration regulation in DOL/FEC electrolytes as an effective strategy for fast graphite lithiation without relying on fluorinated ether solvents or localized high-concentration formulations.

Microemulsion-enabled interfacial design with graphene oxide incorporation and polycarboxylate intercalation. • Sulfate-tolerant design enables lithium recovery from natural sulfate-rich salt-lake brines. • Integrated experiments and DFT/MDsimulations reveal cooperative Li + selectivity. • Column operation demonstrates stable, environmentally benign brine treatment. Adsorption-based lithium extraction provides a convenient, efficient, and environmentally friendly route for recovering lithium from liquid resources. Among existing materials, aluminum-based adsorbents are the only systems that have achieved industrial-scale deployment; however, they still suffer from insufficient lithium uptake and structural deactivation during long-term dynamic cycles in sulfate-type salt-lake brines. To address these limitations, a dual-modified lithium–aluminum layered double hydroxide (PGLH) was synthesized via microemulsion-assisted coprecipitation.Structural characterization and computational analyses reveal that the intercalation of polycarboxylates within the interlayer galleries, coupled with graphene oxide (GO) surface modification, synergistically reinforces the layered framework and enhances Li + selectivity. In gradient-concentration real sulfate-type brines, PGLH delivers a lithium adsorption capacity of 17.8 mg·g −1 . Sulfate resistance experiments and molecular dynamics simulations demonstrated a 260% increase in lithium uptake compared to unmodified adsorbents, along with 96.1% capacity retention after fifty cycles, which is attributed to steric hindrance and electrostatic repulsion that effectively suppress sulfate intercalation. Continuous-flow column tests further verified the material's durability, achieving more than tenfold Li + enrichment and reducing the Mg/Li ratio from 2938:1 to 10:1. These findings provide mechanistic insights and design guidelines for developing robust, selective Al-based lithium adsorbents suitable for sulfate-rich brines. A polycarboxylate and graphene oxide co-modified layered alumina adsorbent (PGLH) was synthesized via a microemulsion-assisted method. Interlayer engineering and surface modification synergistically enhanced Li + selectivity in authentic sulfate-rich brines. Structural characterization, adsorption tests, and DFT/MD simulations demonstrate that interfacial modification stabilizes the layered structure and tunes competitive anion sorption, providing mechanistic insight into selective lithium recovery from complex multi-ion environments.

A CeO 2 nano-coating layer on the LRM particles using a wet-chemical method. • Optimized cathode achieves a high initial discharge capacity of 226.17 mAh/g. • Maintains 75.0 % of its initial capacity after 500 cycles at a high rate of 1 C. • Dual function of CeO 2 : inhibiting interfacial reactions and oxygen buffer. Li-rich manganese-based cathode materials (LRM) are promising candidates for high-energy-density lithium-ion batteries. However, they face significant challenges such as capacity fade and voltage decay during cycling, primarily due to the release of surface lattice oxygen and the dissolution of transition metals. To address these issues, in this study, a Cerium oxide nano-coating layer is applied to the LRM particles using a facile wet-chemical method. Characterization through transmission electron microscopy confirms the presence of a coating layer with approximately 1.9 nm thick on the surface of the LRM particles. The optimized cathode achieves a high initial discharge capacity of 226.17 mAh/g and maintains 75.0 % of its initial capacity after 500 cycles at a high rate of 1 C. The improved electrochemical performance can be attributed to the dual function of Cerium oxide: (1) It serves as a physical barrier that isolates the LRM from the electrolyte, inhibiting interfacial side reactions; (2) it acts as an oxygen buffer layer, stabilizing lattice oxygen through the oxygen vacancies formed by the Ce 3+ /Ce 4+ redox couple. This research presents an effective surface engineering strategy to enhance the stability of anionic redox chemistry in LRM, paving the way for advanced high-energy lithium-ion batteries.

The magnesium-based hydrogen storage composite system Li–Mg–N–H (Mg(NH 2 ) 2 –2LiH) has attracted considerable attention due to its moderate operating temperature and high reversible capacity of 5.6 wt%, but its sluggish hydrogen absorption/desorption kinetics and poor cycling stability limit practical applications. Introducing an efficient catalyst is key to overcoming these issues. Herein, for the first time, an MBene material is introduced into a solid-state hydrogen storage system. Mo 4/3 B 2- x with a flower-like structure is successfully prepared by selective etching of the MAB phase (Mo 4/3 Y 2/3 AlB 2 ) and is then added as a catalyst into the Mg(NH 2 ) 2 –2LiH system. The improving effect and the underlying mechanism on hydrogen storage performance are systematically investigated. The results show that the composite with 10 wt% Mo 4/3 B 2- x exhibits optimal comprehensive performance. The onset temperatures for hydrogen absorption and desorption are significantly reduced from 110/130°C to 65/106°C, respectively. The hydrogen absorption/desorption capacities exceed 4.7 wt% under isothermal conditions at 180°C/170°C, and the apparent activation energy for hydrogen desorption decreases from 117.0 kJ/mol to 87.5 kJ/mol. Remarkably, after 100 cycles, the reversible capacity remains above 4.47 wt%, demonstrating excellent cycling stability. Mechanistic studies combined with DFT calculations reveal that the flower-like Mo 4/3 B 2- x dissociates into fine petals and becomes highly dispersed in the matrix during ball milling. The interaction between the catalyst and the matrix effectively weakens the N–H and Mg–N bonds and promotes the retention of the cubic phase Li 2 MgN 2 H 2 in the hydrogen desorption product, which is more favorable for rehydrogenation. Meanwhile, abundant boron vacancies in the catalyst structure provide fast diffusion channels for hydrogen atoms, and the highly dispersed nano-petals effectively separate the matrix particles, collectively enhancing the kinetics and cycling performance. This work opens a new direction for the application of MBene materials in solid-state hydrogen storage and provides a new strategy for the rational design of high-performance hydrogen storage catalysts.

Silicon oxide (SiOx) has emerged as one of the most promising anode materials for lithium-ion batteries due to its high theoretical capacity, ultralow lithiation/delithiation voltage, and abundant natural resource reserves. However, its severe volume expansion and insufficient cycling stability during lithiation–delithiation processes pose significant challenges to practical applications. Herein, an energy-dissipative sesbania gum-grafted-poly(acrylic acid) (SG-g-PAA) binder is fabricated via free-radical-initiated graft copolymerization for SiOx anodes. The SG-g-PAA binder rationally combines the intrinsic elasticity of the natural SG with the stiffness of PAA to construct a mechanically stable framework. The 3D network balances stiffness and elasticity, effectively accommodating the large volumetric changes while preserving electrode structural integrity during cycling. And the synergistic combination of covalent cross-links and dynamic hydrogen bonding further enhance the long-term cycling stability in SiOx anodes. With this binder, the SiOx electrode delivers a high specific capacity of 1134 mAh g–1 after 250 cycles at a current density of 400 mA g–1. The assembled SiOx@SG-g-PAA||NCM622 full cell showed an 88% capacity retention over 100 cycles at 0.3 C.

This study modified CaWO 4 ceramics through co-doping with Li + and Mo 6+ , and prepared Li x Ca 1-x W 1-x Mo x O 4 (x = 0–0.10) using the solid-state reaction method. The results show that at x = 0.02 and sintered at 850 °C, the material exhibits optimal comprehensive performance: ε r ≈ 9.95, Q × f = 79,683 GHz, and τ f improved from −53 to +5.08 ppm/°C, achieving low-temperature sintering and effective temperature stability control. Mechanism analysis indicates that the enhancement of Mo–O bonds and charge transfer behavior contribute to reducing dielectric loss and improving temperature stability. The material also demonstrates good dielectric performance in the terahertz frequency band. A patch antenna designed based on this material achieves a radiation efficiency of 91.47% at 11.65 GHz, highlighting its potential for application in high-frequency LTCC devices.

Lithium-sulfur (Li–S) batteries are regarded as a promising candidate for next-generation energy storage technologies due to their high theoretical capacity and energy density. However, their practical application remains constrained by critical issues such as the polysulfide shuttle effect and cathode volume expansion. To address this, a multi-functional zwitterionic polyethyleneimine-based binder (PEI-LiCF) was synthesized via nucleophilic substitution between branched polyethyleneimine (PEI) and the highly polar lithium 3-chloropropyltrifluoromethylsulfonyl imide (LiCPSI). Structural analysis confirmed the successful incorporation of oppositely charged groups—quaternary ammonium (positive) and sulfonyl imide (negative)—which form a zwitterionic network. The electrostatic interactions within this network enhance Li+ migration and improve its diffusion kinetics. Furthermore, the abundant polar groups in the network exhibit strong polysulfide-anchoring capabilities. With an optimized PEI:LiCPSI mass ratio of 2 : 1 (denoted PEI-LiCF2), Li–S batteries employing this binder exhibit excellent electrochemical performance, even under a high current density of 1 C. They achieved an initial discharge capacity of 815.7 mAh g−1, maintaining a reversible capacity of 511.9 mAh g−1 after 500 cycles, which corresponds to an ultralow decay rate of merely 0.074% per cycle. This multifunctional water-soluble binder therefore represents a promising candidate material for high-performance Li–S batteries.

Redox-active TNCOF provides ordered nanochannels and regulates Li + deposition. • TNCOF suppresses the decomposition of PEO and guides the formation of a Li 2 O-rich. • Li S battery with TNCOF retains 86.26% capacity after 100 cycles at 0.2C. • LFP battery maintains 93.46% after 400 cycles at 0.5C and 80.95% after 900 cycles at 1C. Solid polymer electrolytes (SPEs) have been widely recognized as promising candidates for safe and high-energy-density solid-state lithium metal batteries. Nevertheless, their practical application is hampered by critical challenges in mechanical properties, ionic transport and interfacial stability. In this work, a redox-active covalent organic framework (denoted as TNCOF) is proposed to modulate interfacial Li + deposition behavior. The TNCOF featuring abundant carbonyls and triazine rings, not only facilitates Li salt dissociation and provides ordered ion conduction pathways but also regulates the local Li + environment through its redox-active units. Consequently, the optimized composite polymer electrolyte (CPE-8%TNCOF) exhibits an excellent performance with an ionic conductivity of 8.35 × 10 −4 S cm −1 , a lithium-ion transfer number ( t Li + ) of 0.45. Moreover, the TNCOF promotes homogeneous Li nucleation and induces the formation of Li 2 O-rich solid electrolyte interphase (SEI). Impressively, the assembled all-solid-state Li S battery delivers a retention of 86.26% over 100 cycles at 0.2C. More notably, the LiFePO 4 |CPE-8%TNCOF|Li battery delivers a discharge capacity of 143 mA h g −1 after 400 cycles at 0.5C, corresponding to capacity retention of 93.46%, and maintains stable operation for 1000 cycles at 1C. This study provids new design ideas and reliable experimental basis for redox-mediated interfacial engineering in solid-state lithium metal batteries.

Garnet-type solid electrolytes hold great promise for solid-state Li-metal batteries owing to their high ionic conductivity, large shear modulus, and excellent Li metal stability. However, their air instability and poor interfacial contact cause high Li/garnet interfacial resistance and Li dendrite growth. Herein, an ionic/electronic mixed-conductive artificial interlayer (denoted as MLPL), consisting of MXene nanosheets, Li 6.4 La 3 Zr 1.4 Ta 0.6 O 12 (LLZT) particles, and a poly(ethylene oxide)/lithium salt (PEO/LiTFSI) matrix, is fabricated at the LLZT/Li interface to address these issues. Incorporating MXene and LLZT suppresses PEO crystallization, enhances segmental motion, and efficiently boosts ionic conductivity. The as-obtained MLPL interlayer is thin (15 μm) and exhibits excellent chemical/electrochemical stability and high ionic conductivity (1.48 × 10 −4 S cm −1 at 60°C). Furthermore, it homogenizes interlayer electric field distribution, mitigates electron-induced garnet attack, improves interfacial contact, accelerates Li + transport, and suppresses dendrite growth, as confirmed by field-emission scanning electron microscopy, electrochemical measurements and COMSOL simulations. Consequently, LiFePO 4 /LLZT@MLPL/Li cells exhibit excellent rate performance (95.4 mA h g −1 at 2.0C) and cycling stability (124.2 mA h g −1 after 100 cycles at 0.1C, 135.6 mA h g −1 after 70 cycles at 0.5C, 60°C). This work offers a universal and feasible strategy for interfacial engineering toward high-performance solid-state batteries. Graphical A mixed ionic/electronic conductive MLPL interlayer stabilizes the garnet/Li interface, homogenizes the electric field, and suppresses Li dendrites for high-performance solid-state Li metal batteries.

To achieve a high efficiency separation of Mg 2+ and Li + , it is essential to precisely regulate the membrane's surface charge density and pore size. This work proposed a strategy for fabricating polyamide (PA) layer with ion-imprinted structures via interfacial polymerization (IP) assisted by ion-imprinting technology (IIT). Cu(II) was added to the Polyethyleneimine (PEI) aqueous phase to regulate the structure of PA nanofiltration (NF) membranes. After removal of Cu(II), PA-IIM 0.16 exhibited a selectivity factor of 44.27 for Mg 2+ /Li + mixture (2000 mg L −1 , 120:1). Upon the completion of the initial NF process, the Mg 2+ /Li + mass ratio underwent a significant reduction, dropping from the starting value of 120 to 2.32. This method facilitates the rapid penetration of Li + while preserving the high rejection of Mg 2+ by meticulously modulating the NF layer in terms of its pore size as well as its surface charge.

Self-supporting Cu/TiN nano-furry serves as a superior bifunctional catalyst for ORR/OER. • DFT reveals Cu/TiN heterojunctions facilitate uniform Li 2 O 2 film growth via enhanced LiO 2 affinity. • Carbon-free catalytic system effectively suppresses Li 2 CO 3 byproduct formation, reducing overpotential. • Delivers ultralow overpotential, high areal capacity and superior stability, outperforming Au-based counterparts. The major hindrance against developing high-performance lithium oxygen batteries (LOBs) lies in their infamously sluggish redox kinetic processes involving undesirable parasitic reactions, which results in large overpotential, low capacity and inferior cycling stability. The rational catalyst design is proposed as an efficient strategy to address the above issue. Herein, we have developed a self-supporting nano-furry cathode based on a Cu foam-supported hierarchical nanotube array architecture decorated with Cu/TiN nanojunctions, which contributes to a fresh bifunctional catalytic mechanism for enhancing ORR/OER catalytic kinetics. Such an integrated cathode with Cu/TiN nanojunctions catalyst enables resilient LOBs through minimizing the energy barriers and excessive input energy to form/decompose Li 2 O 2 , outperforming similar Au-based system. DFT simulation elaborates that the Cu-based heterojunctions with favorable LiO 2 -affinity tend to promote surface deposition of uniform Li 2 O 2 film, alleviating disproportionated reaction and achieving remarkably enhanced capacity. Consequently, this rationally designed cathode for LOBs achieved high area capacity up to 25.6 mAh cm −2 with a small overpotential of 0.37 V at 0.1 mA cm −2 , and exceptional cycle stability with over 350 cycles at 0.2 mA cm −2 under a fixed capacity of 0.25 mAh cm −2 . This work provides an insightful approach towards designing efficient, clean and cheap cathode with abundant metal-based catalysts for LOBs.
