High-energy-density Li-ion batteries are urgently demanded in the development of electric vehicles and smart power grids. Owing to the high theoretical capacity, silicon (Si) has been considered as one of the most promising anode materials for next-generation Li-ion batteries. However, Si anode materials undergo huge volume change during charge and discharge processes, which severely impairs the cycle stability of Si anodes. Herein, to stabilize the Si anodes, a low-cost and eco-friendly network binder coupling hardness with softness was designed through in-situ cross-linking of guar gum (GG) and carboxylated acrylonitrile-butadiene rubber (XNBR). The rigid and high-viscosity GG functions as a skeleton to withstand the expansion of Si active materials, and the elastic XNBR can effectively buffer the residual stress. The mass ratio of GG and XNBR was systematically studied to achieve superior cycling stability of Si anodes. Especially, the Si@X4G6 electrode shows excellent cycle stability, remaining a capacity of 1929 mAh g − 1 at 1000 mA g − 1 after 100 cycles. Interestingly, such an effective strategy not only works well in Si anodes but also does well in Si/C anodes and LiFePO 4 cathodes.

Carbonaceous air cathodes with rational architecture are vital for the nonaqueous Li–O 2 batteries to achieve large energy density , high energy efficiency and long cycle life. In this work, we report the cathodes made of highly ordered and vertically aligned carbon nanotubes grown on permeable Ta foil substrates (VACNTs-Ta) via thermal chemical vapour deposition . The VACNTs-Ta, composed of uniform carbon nanotubes with approximately 240 μm in superficial height, has the super large surface area. Meanwhile, the oriented carbon nanotubes provide extremely outstanding passageways for Li ions and oxygen species. Electrochemistry tests of VACNTs-Ta air cathodes show enhancement in discharge capacity and cycle life compared to those made from short-range oriented and disordered carbon nanotubes. By further combining with the LiI redox mediator that is dissolved in the tetraethylene dimethyl glycol based electrolytes, the batteries exhibit more than 200 cycles at the current density of 200 mA g −1 with a cut-off discharge capacity of 1000 mAh g −1 , and their energy efficiencies increase from 50% to 82%. The results here demonstrate the importance of cathode construction for high-energy-efficiency and long-life Li–O 2 batteries.

Electrolyte additive is an effective strategy to inhibit the uncontrolled growth of Li dendrites for lithium metal batteries (LMBs). However, most of the additives are complex synthesis and prone to decompose in cycling. Herein, in order to guide the homogeneous deposition of Li + , carbonized polymer dots (CPDs) as electrolyte additives are successfully designed and synthesized by microwave (M-CPDs) and hydrothermal (H-CPDs) approaches. The controllable functional groups containing N or O (especially pyridinic- N , pyrrolic- N , and carboxyl group) enable CPDs to keep stable in electrolytes for at least 3 months. Meanwhile, the clusters formed between CPDs and Li + through electrostatic interaction effectively guide the uniform Li dispersion and limit the “tip effect” and dendrite formation. Moreover, as lithiophilic groups increase, the strong electrostatic interference for the solvation effect of Li + in the electrolyte is formed, which induces faster Li + diffusion/transfer. As expected, H-CPDs achieve the ultra-even Li + transfer. The corresponding Li//LiFePO 4 full cell delivers a high capacity retention rate of 93.8% after 200 cycles, which is much higher than that of the cells without additives (61.2%) and with M-CPDs (83.7%) as additives. The strategy in this work provides a theoretical direction for CPDs as electrolyte additives used in energy storage devices.

Searching for a high-power anode material with a low but safe insertion potential is an efficient method for achieving a high-performance Li-ion capacitor (LIC). In this study, we first introduce NaV1.25Ti0.75O4 as a favorable anode for high-performance LIC devices. A series of porous carbon-coated NaV1–xTi1+xO4 (NV1–xT1+x@C) are prepared by a modified two-step solid-state method. Relying on regulating the V/Ti ratio, the average potential can decrease from 0.67 V (NV0.75T1.25@C) to 0.56 V (NV1.25T0.75@C). NV1.25T0.75@C exhibits a high capacity of 379.8 mAh g–1, an excellent rate capability, and a remarkable cyclic stability. Through kinetic analysis, it is proven to possess a fast pseudocapacitive property. The Li+ storage mechanism of NV1.25T0.75@C has been systematically investigated by in situ X-ray diffraction (XRD), ex situ X-ray photoelectron spectroscopy (XPS), and ex situ high-resolution transmission electron microscopy (HRTEM) techniques. Solid-solution insertion-type reaction and 3.5 electron transfer reaction can be found in the Li+ storage process of NV1.25T0.75@C. Through density functional theory (DFT) calculations, an open and large channel with a low Li+ diffusion energy barrier can be found. When employing this low-potential NV1.25T0.75@C as the anode and AC-80F as the cathode, such an LIC full cell can demonstrate a high energy density of ∼107.3 Wh kg–1 at 190 W kg–1, a maximum power density of 15.2 kW kg–1, and a long cycle life of over 3000 cycles. These results indicate that NV1.25T0.75@C can serve as a new promising anode and provides a novel element regulation strategy for achieving low-potential as well as high-power anode materials for LICs.

Recurrent infections and persistent inflammation pose significant challenges in the clinical treatment of infected bone defects. Here, a porous scaffold of Zn-0.8Li-0.5Ag with a TPMS-Gyroid structure was fabricated by laser powder bed fusion (LPBF) for the treatment of infected bone defects, integrating mechanical performance, anti-infective properties, and osteogenic requirements. In vitro, Zn-0.8Li-0.5Ag scaffold exhibits potent bactericidal property against Staphylococcus aureus ( S. aureus ) and Escherichia coli ( E. coli ), excellent anti-inflammatory property through immunomodulation, and acceptable osteogenesis property by enhancing the expression of osteogenesis-related genes. In vivo, the Zn-0.8Li-0.5Ag scaffold significantly suppresses pathogenic bacteria, alleviates local inflammation, and promotes tissue regeneration. RNA sequencing further elucidated that the Zn-0.8Li-0.5Ag scaffold exerted anti-inflammatory effects by releasing Zn 2 + , Li + , and Ag + , which downregulated Gbp2 expression, thereby inhibiting inflammatory pathways. Collectively, the Zn-0.8Li-0.5Ag scaffold with antibacterial, anti-inflammatory, and osteogenic effects holds great promise as a promising biomaterial for repairing infectious bone defects.

The quest for sustainable energy transition has intensified the demand for lithium extraction from salt-lake brines, necessitating advanced membranes for high-efficiency Li + /Mg 2+ separation. Integrating porous frameworks and two-dimensional (2D) scaffolds has shown promise for fabricating ion-permselective membranes, but is hampered by poor processability. Here we transform crystalline frameworks into porous liquids (PLs), and embed them within graphene oxide (GO) laminates to engineer an ultrathin and defect-free GO/PLs membrane. Discrete porous guests are uniformly confined within 2D nanofluidic channels mediated by a sterically hindered solvent. The GO/PLs membrane exhibits ultrahigh Li + permeance (0.75 mol m −2 h −1 ) and exceptional Li + /Mg 2+ selectivity (154.4) by regulating ion dehydration and ion-to-channel interactions. Efficient lithium extraction from simulated brine is demonstrated, reversing the Mg/Li ratio of 40 to achieve a Li/Mg ratio of 4.6. This work reports the manufacturing strategy of hybrid membranes based on porous frameworks and 2D materials for precise ion separation.

Lithium–chalcogenide
batteries (LCBs) offer high theoretical
energy density but suffer from the polysulfide/polyselenide shuttling
during charging and discharging processes with conventional polypropylene
(PP) separators, causing low active-material utilization and severe
capacity decay. Herein, we develop a Phyllostachys edulis bamboo-derived microporous carbon-coated PP
separator (MPC@PP) to suppress polychalcogenide migration and enable
long-term cycling. The abundant micropores in the MPC coating enhance
polysulfide adsorption and boost the Li + transference number
to 0.57, which is a 46.2% increase over pristine PP (0.39). The lithium
symmetric Li/Li cell with MPC@PP exhibits good cycling stability up
to 300 h at 0.5 mA cm –2 (1 mAh cm –2 ) with a smooth and compact lithium deposition. When used in Li–S
battery with the S@Ketjenblack cathode, the MPC@PP cell delivers a
reversible capacity of 1272.92 mAh g –1 at 167.5
mA g –1 and stable cycling over 500 cycles at 837.5
mA g –1 . Moreover, Li–SeS 2 battery
with MPC@PP achieves an initial capacity of 723.48 mAh g –1 at 1342 mA g –1 with average Coulombic efficiency
>99.2% for 500 cycles. This work provides a cost-effective and
scalable
biomass-derived microporous carbon strategy to address the critical
challenges of LCBs, offering valuable guidance for advanced separator
design and accelerating the deployment of high-energy-density rechargeable
batteries.

Sodium-ion batteries are renowned for their abundant reserves, cost-efficiency, safety, and eco-friendliness and are prime candidates for large-scale energy storage applications. The development of cathode materials plays a crucial role in shaping both the commercialization path and the ultimate performance capabilities of SIBs. To overcome the intricate synthesis challenges associated with pure-phase sodium-ion cathode materials, this study introduces an innovative and streamlined electrochemical Li+/Na+exchange process, successfully fabricating a high-capacity Ni-rich cathode material. This cathode material boasts a remarkable reversible capacity of 180 mAh g−1at 0.1 C and retains a high-rate capacity of 115 mAh g−1even at 5 C. Additionally, it exhibits exceptional cycling stability, retaining about 85% of its capacity at 1 C after 50 cycles and still maintaining a capacity greater than 60% after 100 cycles. The Na-NMA85 full cell preserves a discharge capacity of 110 mAh g−1after 100 cycles, with a capacity retention rate of 80%. This research underscores innovative strategies for designing ion-intercalation-based cathode materials that enhance battery performance, providing fresh perspectives for advancing high-performance battery technologies.

Gel-polymer electrolytes are considered as a promising candidate for replacing the liquid electrolytes to address the safety concerns in Li–O 2 /air batteries. In this work, by taking advantage of the hydrogen bond between thermoplastic polyurethane and aerogel SiO 2 in gel polymer, a highly crosslinked quasi-solid electrolyte (FST-GPE) with multifeatures of high ionic conductivity, high mechanical flexibility, favorable flame resistance, and excellent Li dendrite impermeability is developed. The resulting gel-polymer Li–O 2 /air batteries possess high reaction kinetics and stabilities due to the unique electrode–electrolyte interface and fast O 2 diffusion in cathode, which can achieve up to 250 discharge–charge cycles (over 1000 h) in oxygen gas. Under ambient air atmosphere, excellent performances are observed for coin-type cells over 20 days and for prototype cells working under extreme bending conditions. Moreover, the FST-GPE electrolyte also exhibits durability to protect against fire, dendritic Li, and H 2 O attack, demonstrating great potential for the design of practical Li–O 2 /air batteries.

GLDA chelator locks Li + via multidentate coordination, preventing salt leakage. • Combining directional freezing with in-situ polymerization rapidly locks pore structure. • High water uptake and a rapid adsorption, combining high capacity with fast kinetics. • Outdoor all-weather water harvesting, the produced water meeting WHO standards Sorption-based atmospheric water harvesting (SAWH) using hygroscopic salts offers promising decentralized freshwater supply, though deployment faces challenges like salt migration and adsorption-rate decay due to brine dilution. We introduce an ion-locking, thermoresponsive hygroscopic gel that enhances Li + fixation and vapor/liquid transport. Created via synergistic directional freezing and UV polymerization, the gel features an interpenetrating PNIPAM/PAA network with hierarchical macroporous architecture Aligned macrochannels facilitate low-resistance vapor diffusion and hierarchical macroporous architecture enhance water capture and storage. To prevent Li + loss, glutamic acid diacetic acid is grafted onto chitosan, providing multidentate chelation verified by XPS/Raman analyses and DFT calculations, securing Li + against hydration. PPCG-LiCl achieves high water uptake of 1.6 g g −1 at 30% RH and 6.8 g g −1 at 90% RH, with maximum sorption rates of 1.4 g g −1 h −1 and 2.9 g g −1 h −1 respectively, maintaining performance through long-term cycles. PNIPAM's LCST-triggered transition allows rapid solar desorption (≈80% water released in 20 min), supporting a fast-cycle SAWH device delivering daily yields of 2.53/3.92/5.85 g g −1 in various outdoor conditions, and generating water with ultralow Li + concentration (0.005 mg L −1 ). This innovation offers a practical material solution for stable, efficient SAWH.
