The development of solid-state lithium metal batteries (SSLBs) faces challenges like high interfacial resistance, volume fluctuations, and lithium dendrite growth. This work employs a template method to in situ construct a three-dimensional (3D) metallic nanonetwork with mixed ionic/electronic conductivity (MIEC) on Ta-doped LLZTO solid electrolyte. This structure not only remains stably anchored at the LLZTO interface but also exhibits excellent electronic conductivity, enabling a more uniform electron distribution across the heterogeneous interface. Benefiting from this interfacial design, the lithium symmetric cells achieve a high critical current density (CCD) of 1.5 mA cm–2 and stable cycling for 3000 h at 0.5 mA cm–2 and maintain robust performance for more than 100 h at 1.0 mA cm–2. The assembled full cells exhibit exceptional electrochemical performance, and this method provides a paradigm for interfacial structural design in SSLBs.

The progress in energy storage technology has primarily focused on practical applications, necessitating straightforward fabrication, economical materials, and scalable manufacturing. In this work, we demonstrate a facile method to prepare highly self-catalytic cathodes for lithium‑oxygen batteries (LOBs) using bacterial cellulose (BC) as a precursor. The BC-derived cathodes (CBC) retain both the fibrous structure and oxygen-functional groups of the original biomass, producing a material with a modest appearance but outstanding electrochemical properties. The oxygen-functional groups incorporated into the carbon framework exhibit synergistic catalytic effects, enabling an unprecedented discharge capacity of 33,900 mAh g −1 at 200 mA g −1 , significantly outperforming most reported cathodes. An integrated oxygen-selective membrane, formed via a facile silicone oil coating process, resulting in stable cycling at current densities up to 1000 mA g −1 and continuous operation for over 240 h in ambient air when coupled with a hybrid polymer electrolyte, highlighting its practical viability. Furthermore, the eco-friendly and self-catalytic CBC represents an innovative “three-in-one” electrode design, simultaneously providing a 3D conductive network, efficient catalytic centers, and selective oxygen transport capabilities, all crucial features for next-generation energy storage systems.

Tailoring the crystalline structure and facet orientation of T-Nb2O5 anode electrodes is pivotal for optimizing the Li+ transport kinetics. Herein, a crystallization engineering strategy is employed to synthesize urchin-like T-Nb2O5 microspheres composed of single-crystalline whiskers growing along the (001) orientation. These whiskers are characterized by nearly 100% exposed vertical (001) facets that accelerate Li+ diffusion. Furthermore, the remaining N3– expands the interlayer spacing, which optimizes Li+ transport pathways. Benefiting from these synergetic effects, abundant ion entry and exit sites with smooth ion transport channels promote the rapid Li+ diffusion in the T-Nb2O5 microspheres, delivering a high capacity and improving the rate performance (324 mAh g–1 at 0.05 A g–1, 87.5 mAh g–1 at 5 A g–1). This work presents a strategy of crystallization engineering for the preparation of fast-charging electrode materials and provides deep insights on the correspondence among morphology, lattice structure, and electrochemical performance.

The metallic phase MoS 2 (1T-MoS 2 ) supported metal-nanocatalyst is an appealing material system for accelerating the redox kinetics of non-aqueous Li | |O 2 batteries. However, the drawbacks associated with the surface orbital steric effect and the internal electron coupling results in a detrimental effect for the stability of 1T-MoS 2 , especially for the interface charge transfer. This makes it difficult to incorporate guest metal nanoparticles without compromising the 1 T phase support. To circumvent these issues, here we propose a p-block element (In-O) doping strategy to stabilize the 1 T phase MoS 2 by moderating the surface orbital steric effect and strengthening the internal chemical bonding, and thus for the epitaxial Ru nanocatalyst graft on the stabilized 1T-MoS 2 for Li | |O 2 batteries. The experimental and theoretical analyzes indicate that the In-O-MoS 2 @Ru enhances the O 2 dissociation and facilitates the adsorption of LiO 2 intermediates. This effect promotes the growth of weakly crystalline Li 2 O 2 films during oxygen reduction reaction, which can be more easily decomposed during the oxygen evolution reaction, thereby enhancing the bifunctional-catalytic kinetics. When employed at the positive electrode for non-aqueous Li | |O 2 batteries, In-O-MoS 2 @Ru shows an overpotential of 0.37 V and a cycling life of 284 cycles at 200 mA g −1 with a final discharge specific capacity of 1000 mAh g −1 at 25 °C.

Recycling the positive electrode materials of spent Li-ion batteries is critical for environmental sustainability and resource security. To facilitate the attainment of the goal, this study presents a novel approach for recovering valuable metals from positive electrode materials of spent lithium-ion batteries (LIBs) in an H-shaped cell containing aqueous NaCl electrolyte. The process employs hydrochloric acid that could be derived from the chlorine cycle as the leaching agent. The electrolytic device is engineered to generate a high pH gradient, thereby enhancing the leaching of metal elements and eliminating the requirement for external acid or base addition. This green recycling approach adheres to the principles of a circular economy and provides an environmentally friendly solution for sustainable battery material recycling.

Li-O2 batteries have emerged as promising contenders for advanced energy storage systems, leveraging their exceptionally high theoretical energy density. Nevertheless, their practical deployment is substantially hindered by rapid capacity degradation and restricted operational durability, primarily attributed to sluggish oxygen reaction kinetics. Here, to modulate kinetic barriers, we propose an approach synergizing structural and electronic advantages by integrating heterointerface engineering and hierarchical nano structuring. A hollow nanobox MoSe2@CuS core-shell heterostructure is developed as a bifunctional oxygen electrode. Such heterostructure could induce a built-in electric field to modulate charge transfer dynamics and the hollow architecture could optimize triple-phase interfacial reactions. Leveraging the synergistic attributes of its components, the MoSe2@CuS-based Li-O2 battery achieves an excellent specific capacity of 16,000 mAh g-1 at 100 mA g-1. Moreover, it demonstrates remarkable cycling durability, sustaining high performance for over 190 cycles at 200 mA g-1 with a restricted capacity of 600 mAh g-1. Density functional theory (DFT) calculations further illustrate the lowered energy kinetic barrier for Li2O2 formation/decomposition induced by MoSe2@CuS core-shell heterostructure. This work pioneers a universal heterointerface engineering strategy through rational design of hierarchical hollow architectures, providing new insights for developing high-performance Li-O2 battery cathodes.

The development of nickel-metal hydride battery anodes has long been limited by the inherent capacity decay of the anodes of the metal alloy materials. In this study, the BaCe 1-x Li x O 3 solid solutions with controlled contents of Li + ions (x = 0–0.8) were synthesized via combustion method and adopted them as the novel negative materials to offer a breakthrough in overcoming traditional performance constraints. The influences of Li + contents on microstructure and electrochemical hydrogen storage performance were systematically investigated. X-ray Diffraction test (XRD) confirmed that the Li + ions were successfully incorporated into the BaCeO 3 lattice and substituted at the Ce 4+ sites. The grain sizes were gradually decreased from 73.5 nm (undoped) to 67.0 nm (Li 0.08 ). Scanning Electron Microscope (SEM) and Transmission Electron Microscope (TEM) results further supported the reduction of the grain sizes and proved that the Li + ions had doped into the lattice of the BaCeO 3 . Spectral tests showed that the Li + ions induced obvious changes in the lattice structures and the concentration of oxygen vacancies. Electrochemical hydrogen storage performance tests demonstrated that the discharge capacity of BaCe 0.96 Li 0.04 O 3 achieved 212.7 mAh/g, representing 95.1 % improvement over the undoped sample (109.0 mAh/g), along with higher charge retention. Kinetic analysis further confirmed the superior hydrogen storage kinetic behavior of the doped samples. These results fully proved that the doping of Li + ions can effectively enhance the hydrogen storage performances of BaCeO 3 materials.

Li metal anode suffers from poor interfacial stability and safety hazards in liquid electrolytes. Designing stable interface on Li metal and replacing liquid electrolytes are critical ways to develop high-energy-density lithium metal batteries (LMBs). In this paper, a superior MgF 2 -containing interface was first studied, and an interface-derived high-performance solid polymer electrolyte (SPE) was prepared by a facile solution casting method. A LiF-rich interface containing Mg atoms is in-situ generated by the reaction between MgF 2 and metallic Li, which simultaneously enhances the interfacial stability and endows dendrite-free Li deposition, enabling the Li metal anodes to realize long-term stable cycling even at 5C (3.04 mA cm −2 ) in commercial carbonate electrolytes. The interface-derived SPE has high room-temperature (RT) ionic conductivity, Li-ion transference number, excellent interfacial compatibility and stability due to the existence of MgF 2 . Under the joint action of stable interface and high-performance SPE, the all-solid-state LMBs can exhibit ultra-stable cycling with high coulombic efficiencies under RT. This work provides a guideline for the development of superior interfaces and high-performance SPEs by learning from each other.

The uncontrollable Li dendrite accumulation accompanied by low Coulombic efficiency severely hampers the sustainable and practical application of lithium metal batteries (LMBs). To tune the uneven Li + flux caused by irregular pores on commercial separator and realize modulated Li + plating/stripping behaviors, in this work, we report the modification of commercial polypropylene separator with etched Co/Fe-based Prussian blue analogue (PP@PBA-X, X represents the HCl etching time). The optimal PBA-4 with acid etching for 4 h possesses regulated micro-/meso-/macro-porous structure, which ensures homogeneous Li + flow of PP@PBA-4 with high Li + transference number of 0.76 and further hinders the growth of Li dendrites. With the assistance of PP@PBA-4, the Li||Li cell shows stable cycling performance for 500 h at 1 mA cm −2 with fixed specific capacity of 1 mAh cm −2 , while the full Li-S battery with limited Li supply delivers favorable cycling stability for almost 430 cycles with 60 % capacity retention and high Coulombic efficiency of 99.95 % at current density of 500 mAg −1 .

The new composite fuel (Al-Li@TH@AP@Oxide) is a better strategy to improve the combustion effect of propellant through the structural design. This study focuses on the micro-explosion effect of Al-based alloy fuel, the improvement of surface oxygen concentration and the reduction of the distance between metal oxide and reducing agent. The stabilized Al-Li had good compatibility of 1 level with HTPB and curing property through the passivation of tris(hydroxymethyl)aminomethane hydrochloride (TH). Besides, the ammonium perchlorate (AP) and oxide could be attached to Al-Li@TH surface through evaporation induced self-assembly (EISA) method. The Al-Li@ [email protected] had the AP coating layer of 53.26 nm and good flammability with the reaction of oxidant and reducing agent. Moreover, the samples of Al-Li@ [email protected] @Oxide had better flammability with shorter ignition delay time, greater burning intensity and obvious micro-explosion phenomenon. The high temperature decomposition exothermic peak of AP could also be reduced to 344.8℃ of Al-Li@ [email protected] @CuO from 413℃ of Al-Li@ [email protected] . The doping of CuO presented the minimum ignition delay time of 0.6594 s, the highest burning temperature of 1343.28℃ and the fastest burning rate of 1.5297 mm s −1 through the comparison of Mn 2 O 3 , NiO and CuO propellants. In addition, the better combustion effect and structural advantage could also be proved through the size and composition of residue for the propellants of Al-Li@ [email protected] @CuO than Al-Li@TH/AP/CuO. The appearance of Al 2 O 3 and metal proved the occurrence of thermite reaction during propellant combustion. The feasible fabrication method would provide an innovative idea for further development of solid propellants with high combustion performance.

The Li–CO 2 battery, capable of both efficient carbon dioxide fixation and high energy density storage, holds promise in mitigating the greenhouse effect and alleviating mileage anxiety. However, the volatilization/leakage problems of the conventional electrolytes and the dendrites crisis of lithium anode seriously affect the battery life. The replacement of the organic electrolyte with a solid one is a feasible method to solve the above problems. Till now, the poor interface contact between solid electrolyte and electrode restricts the Li + ions transport kinetics in discharge/charge cycles. Herein, we apply a solution casting method to prepare a flexible polymer/ceramic composite electrolyte. With the combination of high Li + ions conductivity ceramic filler of Zn-doped Li 1.3 Al 0.3 Ti 1.7 (PO 4 ) 3 (LATP) and Lithium bis(trifluoromethanesulfonyl)imide (LiTFSI) active additive, the crystallization of polyvinylidene fluoride (PVDF) and poly (ethylene oxide) (PEO) is suppressed, thus efficiently enhancing the room temperature Li + ions conductivity (8.32 × 10 −4 S cm −1 ) of the composite electrolyte. The Li–CO 2 battery with the solid-state electrolyte exhibits a high discharge capacity (32,842 mAh g −1 ) and long stable cycles (over 220 cycles). The polymer/ceramic composite electrolyte design presents a novel approach to realizing solid-state Li–CO 2 batteries with long-term cycling performance.

Interfacial modification strategies for lithium metal anodes have emerged as a promising method to improve cycling stability, suppress lithium dendrite growth, and increase Coulombic efficiency. However, the reported chemical synthesis methods lead to side reactions and side products, which hinder their electrochemical performance. In this study, we propose a novel and facile red phosphorus-assisted solid-state friction method to in situ fabricate a uniform Li3P interphase directly on the surface of lithium metal. Interestingly, the as-formed artificial Li3P interphase with high ionic conductivity and lithium affinity features significantly enhanced interfacial stability and electrochemical kinetics. The symmetric cells based on Li@P with the Li3P interphase achieved a prolonged lifespan, over 1000 h, at 1 mA/cm2with low polarization. When paired with a high-loading LiFePO4cathode (10.5 mg/cm2), the Li@P||LiFePO4full cell retained 88.9% of its capacity after stable cycling for 550 cycles at 2 C and further demonstrated the excellent performance and stability of the Li@P‖LiCoO2full pouch cell. This study provides an efficient and scalable strategy for stabilizing lithium metal anodes, expanding new ideas for the development of next-generation high-energy-density batteries.
