Halide perovskite materials have garnered significant attention due to their outstanding optoelectronic properties; however, their development was limited by their low stability and lithium storage performance. In this study, CsMnCl3·2H2O and CsMnCl3 were synthesized via the solid-state synthesis method and selected to demonstrate the effects of crystalline water on their lattice transformation and electrochemical properties. The results indicate that the presence of crystalline water alters the Li+ insertion/extraction sites, thereby promoting Li+ insertion/extraction kinetics and lattice stability, resulting in the specific capacity of CsMnCl3·2H2O being 103.7 mAh·g–1, which is higher than the 57.7 mAh·g–1 of CsMnCl3 after 200 charge/discharge cycles, and the Coulombic efficiency of both approaching 100%. Besides, the density functional theory (DFT) calculations were used to demonstrate the influence of crystalline water on the halide perovskite lattice. This study not only opens new avenues for optimizing halide perovskite materials as high-performance lithium-ion battery anodes but also provides theoretical support for understanding the Li+ insertion sites in halide perovskite lattices for halide solid-state electrolytes.

Escalating requirements for energy density, fast-charging capability, and operational safety in lithium-ion power batteries demand separators with exceptional structural stability and ion-transport efficiency. Herein, a flexible, improved-wettability polyimide membrane derived from a diamine monomer containing cyano groups is synthesized via electrospinning. The interconnected pore structure and high porosity of the cyano-based polyimide separator deliver the desired electrolyte wettability (405%) and thermal stability. Importantly, the introduction of polar cyano groups with a high dielectric constant provides a high anodic oxidation potential. The lithium-ion battery assembled with the cyano-based polyimide separator provides strong coordination with Li+, exhibiting elevated ion conductivity (1.04 mS cm–1, 25 °C) and high-rate performance, delivering a capacity of 98.4% at a rate of 0.5 C after 200 cycles. Moreover, the cyano-based polyimide separator displays great cycling durability and capacity retention (99.5%, 133.6 mAh g–1) even at 100 °C. The above-mentioned properties imply that cyano-containing polyimide nanofibrous membranes are outstanding candidates as separators in the high-capacity lithium-ion battery industry.

Lithium-rich manganese-based oxides (LRMO) are promising cathodes for high-energy-density lithium-metal batteries owing to their high operating voltage and large reversible capacity, but suffer from severe interfacial degradation at high voltages (≥4.8 V), primarily triggered by lattice oxygen release, electrolyte oxidation, and HF-induced corrosion. Herein, we design a multifunctional siloxane-based electrolyte additive, 1,3,5-tris(3,3,3-trifluoropropyl)methylcyclotrisiloxane (TFSO), to regulate these coupled degradation processes. TFSO simultaneously acts as an oxygen scavenger and HF trap, suppressing lattice oxygen reactivity while converting HF into stable Si F/Si O species. Meanwhile, it promotes the formation of robust, inorganic-rich CEI/SEI layers, enabling dual interfacial stabilization and uniform lithium deposition. In addition, TFSO reconstructs the Li + solvation structure, reducing solvent participation in interfacial side reactions. As a result, the LRMO‖Li cell achieves 92.7% capacity retention after 300 cycles at 4.8 V, along with excellent wide-temperature performance (82.7% at 55 °C and 160 mAh g −1 at 0 °C). This work highlights an effective electrolyte design strategy for mitigating oxygen-triggered interfacial degradation in high-voltage lithium metal batteries. A multifunctional siloxane-based additive (TFSO) enables stable cycling of LRMO||Li batteries at 4.8 V by scavenging lattice oxygen and corrosive HF, forming robust dual interphases, and regulating Li + solvation to deliver excellent performance and wide-temperature tolerance.

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.

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.

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.

O3-type NaNi 2/9 Fe 1/3 Cu 1/9 Mn 1/3 O 2 is considered a promising layered oxide cathode for sodium-ion batteries, owing to its high operating voltage and cost-effective elemental composition. However, its practical application is hindered by irreversible phase transitions at high voltages, which severely compromise structural integrity and cycling stability during prolonged operation. To address these challenges, elemental doping has emerged as an effective strategy to modulate crystal lattice parameters and suppress detrimental phase evolution. In this study, we propose a multi-element (Li/Mn/Al) doping approach, synthesized via a hydroxide-precursor-assisted sodiation process, to enhance the structural robustness and electrochemical performance of O3-type NaNi 2/9 Fe 1/3 Cu 1/9 Mn 1/3 O 2 . Specifically, Aluminum doping serves as a structural pillar to stabilize the transition metal-oxygen (TM-O) framework, effectively mitigating layer gliding. Meanwhile, Li doping activates the Fe 3+ /Fe 4+ redox couple, enabling charge compensation and enhancing reversible capacity. Benefiting from the synergistic effects of Li/Mn/Al co-doping, the resulting Na(Ni 2/9 Fe 1/3 Cu 1/9 Mn 1/3 ) 0.96 Mn 0.02 Al 0.01 Li 0.01 O 2 cathode demonstrates suppressed Jahn-Teller distortion, improved air stability, and superior cycling performance. Notably, a reduced interlayer distance ratio ( d (O Na-O) / d (O-TM-O) ) correlates with delayed O3-to-P3 phase transformation and enhanced lattice stability, as confirmed by crystallographic analyses. The synergistic effects of Li/Mn/Al co-doping not only stabilize the host structure but also unlock cationic redox reversibility, offering a pathway to balance energy density and longevity in sodium-based cathodes.

Flexible lithium–air batteries (LABs) with a redox mediator (RM) in the electrolyte demonstrate enhanced round-trip efficiency. However, their cycle performance is unsatisfactory due to severe corrosion of the Li metal anode. Herein, we propose a two step gelatinization strategy to fabricate a gradient RMs (including LiI, TMPD, and DMPZ) gel electrolyte, in which the bare electrolyte gelatinization on the Li surface and then the electrolyte contained RMs sequentially gelled on the formed gel. The RMs mainly distributed at the surface and anchored at the cathode side. By suppressing the shuttle of RMs in the electrolyte and alleviating the passivation of the Li anode, the mid-charging potentials can reach 3.44 and 4.08 V at the 15th cycle with and without the LiI mediator, respectively. The energy efficiency is 63% even at the 150th cycle, whereas the corresponding energy efficiency are only 47% and 51% for the LABs with liquid and normal gel electrolytes, respectively. Moreover, the cycle life of the battery containing the gradient gel electrolyte is three times longer than that with the liquid electrolyte. The gel electrolyte further offers the flexibility of the device, and the laminated cells thus fabricated can readily operate under harsh bending conditions.

Lithium rich manganese based materials (LMR) have promised the likeliest candidate for next generation lithium-ion battery cathodes owing to its high energy density and low materials cost. However, severe capacity decline and voltage decay hinder their practical application, which is closely concerned with the structure degradation and irreversible oxygen release. Herein, a simple strategy to reinforce the structural stability of LMR materials by constructing heterostructure with Nb-based MXenes (Nb 2 CT x / Nb 4 C 3 T x ) is proposed. A small amount of spinel phase and pseudo-bonding between Nb and O ions as well as extra oxygen vacancies can be induced by the MXenes addition in LMR, effectively inactivating the surface oxygen and suppressing the structure distortion. In addition, MXene can also alleviate the volume change during cycling process and provide additional transport channels for electrons. The ably designed 3 wt% LMR/Nb 2 CT x cathode presented high initial Coulombic efficiency of 85.6% at 0.1C (vs. 77.4% for the pristine material) and excellent cycling performance with a capacity retention of 83.8% after 200 cycles at 0.5C (vs. 66.6% for the pristine material). This work sheds some light on stabilizing the structure of lithium-rich manganese materials and provides a new idea for the design of other high performance cathode materials.

Li-rich Mn-based oxides (LRMO) greatly increase its output energy density due to its additional oxygen redox activity. However, the inherent oxygen loss and irreversible phase transition induce low initial coulombic efficiency and serious voltage decay, further seriously impeding its industrial application. Herein, a near-surface in-situ reconstruction strategy has been proposed, which constructs the oxygen vacancies and spinel phase coating on the surface of single-crystal Li-rich Mn-based oxide (SC-LRMO) concurrently to improve Li + storage performance via the oxalic acid induction method. Intensive exploration based on structure characterizations demonstrates that such a near-surface in-situ reconstruction strategy not only accelerates the transmission of Li + , but also stabilizes high-voltage redox reactions by trapping the escaping O n− within the newly formed spinel phase coating. Impressively, the modified sample exhibit 91.1% capacity retention ratio after 300 cycles, superior to the SC-LRMO (74.5% capacity retention ratio after 300 cycles). Additionally, even at a high cut-off voltage of 5 V, the acid etched sample exhibits significantly enhanced cycling stability, delivering 200 mAh g −1 with a 94% capacity retention ratio after 300 cycles. This surface self-reconstruction strategy provides profound insights into regulating the surface structure of LRMO for high-energy-density lithium-ion batteries.

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.
