Lithium-carbon dioxide (Li-CO 2 ) batteries , especially solid-state Li-CO 2 batteries , have attracted much attention due to the high energy density and potential application of carbon neutrality. However, the extremely sluggish kinetics of CO 2 evolution reaction in the batteries result in a notorious high-charge-potential over 4.0 V, thus impeding the development of Li-CO 2 batteries. Here, by in-situ constructing a plasmonic Ru/Li 2 CO 3 -based heterostructure , we report an ultra-low charge overpotential and long cycle life solid-state Li-CO 2 battery via the energetic hot carries produced by nonradiative decay of localized surface plasmons where solar energy can be efficintly harvested (over 90% absorption efficiency from 200 nm to 1000 nm), concentrated and converted on the plasmonic Ru catalysts. Experimental results show that the plasmonic photothermal catalysis using Ru catalysts can catalyze C-O bond cleavage and construct a plasmonic Ru/Li 2 CO 3 -based heterostructure in the battery on discharge, and effectively accelerate the CO 2 envolution reaction via injecting the hot carriers generated from the plasmonic Ru catalysts into the discharged Li 2 CO 3 -based products on charge. As a result, by using a chemically stable and high Li-ion conductive MSI layer , the battery shows a record low charge potential (2.99 V) even after a long-term cycling (over 450 cycles) operating at 500 mA g −1 at 500 mAh g −1 . This battery technology paves the way for developing next-generation high-specific-energy Li-CO 2 batteries with carbon neutrality.

All-solid-state batteries (ASSBs) with a Li metal anode are expected to be one of the most promising energy storage systems to achieve high energy density. However, the interfacial instability between the Li metal anode and solid-state electrolyte (SSE) limits the rate capability and cycling stability of ASSBs. The main issue is the formation of voids at the Li/SSE interface during Li stripping due to the slow diffusion of Li within the bulk Li metal, then increasing internal cell resistance and inducing the formation of lithium dendrites. To address these issues, a composite Li anode (LAO) composed by Li–Ag alloy and Li2O is constructed by mixing the stoichiometric metal Li and Ag2O directly. LAO anode is capable of improving bulk Li diffusion kinetics and inhibiting the formation of interfacial voids effectively, achieving a high critical current density over 1.5 mA cm–2 and long stable cycling over 1000 h at 1 mA cm–2. The ASSBs, employing LAO as the anode, Li6PS5Cl as the SSE, and LiCoO2 as the cathode, exhibit superior rate capability and stable cycling over 4000 cycles at 5 C. Moreover, ASSBs can operate stably with a high LiCoO2 loading of 17.8 mg cm–2 for more than 100 cycles at 0.2 C.

Recycling and utilization of valuable metals from spent ternary lithium-ion batteries possess significant economic and environmental benefits. Recycling of valuable metals effectively compensates for the high costs, poor selectivity, and low utilization rates of active sites present in single Pt-catalyzed hydrogen evolution reaction (HER). Hence, developing high-efficiency catalysts with multi-metal active centers to synergistically promote H 2 O dissociation and H 2 evolution is critical for accelerating alkaline HER. In response, we first report an ultra-small high-entropy alloys (HEAs) nanoparticle catalyst by mixing valuable metals (Ni, Co, Mn) recycled from spent ternary Li-ion batteries with Pt driven by non-equilibrium high-temperature-shockwave. As expected, due to high-entropy coordination environment, well-designed NiCoMnPt HEAs catalyst possesses multiple activated metal centers, thus achieving much-improved HER performance (ultra-low overpotential of 16.6 mV@10 mA cm −2 ). Experimental and theoretical studies indicate the mutual substitutions among NiCoMnPt atoms cause lattice distortion and induce electronic coupling effect, which optimizes the electronic structure of Pt and makes the deeply activated Pt as fundamental active center for H 2 O dissociation. Accompanied by electrons redistribution, NiCoMn as electron-rich centers further contribute to reducing the H 2 desorption energy barrier and greatly accelerating the hydrogen evolution efficiency. Impressively, this work provides fresh ideas for constructing high-efficiency electrocatalysts beyond HER.

Li–O2 batteries (LOBs) boast an exceptionally high theoretical energy density; however, the slow kinetics of the oxygen electrode reaction have been a significant hurdle in their advancement and practical application. In this study, a composite of bismuth oxyhalide heterojunction incorporated with metal–organic frameworks (MOFs) was engineered on carbon cloth (Zr-MOF/BiOIBr/CC) as an efficient bifunctional catalyst to enhance the oxygen electrode reaction in photo-assisted LOBs. Compared to Zr-MOF/CC, Zr-MOF/BiOIBr/CC significantly expands the light absorption spectrum of the catalyst. Furthermore, the built-in electric field in the heterojunction aids in the separation and directional movement of photogenerated carriers, thereby expediting the reaction kinetics of LOBs. Consequently, the photo-assisted LOBs with Zr-MOF/BiOIBr/CC as the cathodes display a discharge potential of 3.05 V, a low charge potential of 3.20 V, and an energy efficiency of up to 95.3%, and can sustain an extended cycle life of over 255 cycles. This study underscores the potential application of MOFs/semiconductor heterostructural materials in photo-assisted LOBs and offers insights into the systematic design of photo-assisted air batteries and other advanced semiconductors.

The superior combustion heat, lower ignition temperature, and enhanced combustion efficiency of aluminum–lithium (Al-Li) alloy powders have garnered significant research attention in relation to Al powders. However, the inadequate compatibility between Al-Li alloy powders (especially when Li > 3 wt%) and propellant components limits its application in the development of composite solid propellants. This study focuses on the surface-coating active Al-4.3Li (wt.%) alloy powder using a composite fluorosilane coupling agent to improve compatibility and combustion performance. A coating layer with a thickness of 30–40 nm was successfully formed on the surface of Al-4.3Li alloy powder through interactions involving Al-F, Al-O-Si, and Li-O-Si bonds, thereby achieving remarkable hydrophobicity. The heat release increased by 7.5 %, while the ignition delay time of the alloy powder decreased by nearly 200 ms, resulting in a significantly enhanced combustion performance in relation to that of the original Al-4.3Li alloy powder. Moreover, the modified Al-4.3Li alloy powder exhibited better compatibility, and no cracks or bubbles were observed in the cross-section of the propellant containing modified Al-4.3Li metal fuel. This study provides an effective approach for utilizing Al-Li alloy powders in solid propellants, which is of great significance for the development of high-energy propulsion systems.

Sulfide solid electrolytes (SEs) represent one most promising technical routes to realize all-solid-state batteries (ASSBs) due to their high ionic conductivity and low mechanical stiffness. However, the poor air/moisture/water stability of sulfide SEs leads to completely destroyed structure/composition, reduced Li + conductivity, and toxic H 2 S release, limiting their practical application in ASSBs. To solve this problem, a universal method applicable to all types of sulfide SEs is developed to realize water-stable sulfide SE membranes, by spray coating a Li + -conductive superhydrophobic protection layer with Li 1.4 Al 0.4 Ti 1.6 (PO 4 ) 3 (LATP) nanoparticles and fluorinated polysiloxane (F-POS) via hydrolysis and condensation of tetraethyl orthosilicate and 1 H ,1 H ,2 H ,2 H -perfluorodecyltriethoxysilane molecules. The F-POS@LATP coating layer exhibits excellent superhydrophobicity (water static contact angles > 160°) to resist extreme exposure (direct water jetting), because of its micro-/nanoscale roughness and low surface energy. Moreover, ASSBs using the extreme-condition-exposed modified Li 6 PS 5 Cl membrane exhibit a reversible capacity of 147.3 mAh g -1 , comparable with the ASSBs using pristine sulfide membranes. The superhydrophobic Li + -conducting layer is demonstrated to be an effective protection method for sulfide membranes so that they remain stable and functionable in extreme water exposure conditions, providing a new approach to protect all types of sulfide SEs and other air/moisture/water-sensitive materials without sacrificing electrochemical performance.

Defect-assisted epitaxial growth of metal–organic frameworks (MOFs) on conductive substrates offers an efficient strategy for enhancing electrochemical performance. In this study, a rational approach is proposed to promote the epitaxial growth of ZIF-67 on graphene by precisely tuning the Co 2+ to 2-methylimidazole molar ratio, thereby improving lithium-ion storage capabilities. The resulting NiCo 2 O 4 @ZIF-67/graphene (NCO/Z67G-2) composite exhibits outstanding electrochemical performance, delivering a high reversible capacity of 1298.5 mAh g −1 after 100 cycles and a rate capability of 601.1 mAh g −1 at 1.4 A g −1 . Structural characterization indicates that optimized metal–ligand coordination facilitates defect-assisted epitaxial growth of ZIF-67 along the (001) crystal plane, resulting in a highly conductive interface enriched with Co-N-C active sites. Electrochemical analyses further reveal that the superior performance stems from a capacitive-dominated lithium storage mechanism, fast ion diffusion kinetics, and the formation of a thin and uniform LiF-rich solid electrolyte interphase (SEI), which collectively contribute to the reduced charge transfer resistance (88.01 Ω). This study provides valuable insights for the rational design of advanced electrode materials via interface engineering and defect regulation in high-performance energy storage systems.

The catalytic conversion of polysulfides remains a critical bottleneck in the development of high-performance lithium–sulfur batteries (LSBs). Despite extensive efforts to engineer carbon-based materials for LSBs, such as nitrogen (N)-doped graphene, the intrinsic limitations of conventional N-doped configurations have hindered catalytic effectiveness. Here, we reveal how the curvature-rich structure of N-doped graphene (N-CR-G) regulates catalytic properties to promote the sulfur reduction reaction (SRR). This architecture induces a diversity of active N configurations and optimizes the local electronic structure, directly accelerating the polysulfide redox kinetics. Unlike conventional carbon-based materials, the main N-doped configuration of N-CR-G catalyzes an uncommon asymmetric reaction pathway involving the rapid generation of soluble radicals, effectively suppressing the accumulation of insoluble Li 2 S 2 intermediates and enhancing sulfur utilization. While the curvature structure also facilitates carbon vacancy formation and enables room-temperature N doping, its primary contribution lies in tailoring the catalytic landscape of graphene. This work underscores the significance of curvature engineering for activating and regulating electrocatalytic behavior, offering a powerful strategy to design advanced cathode materials for highly promising LSBs.

Low ionic conductivity is a major obstacle for polymer solid-state electrolytes. In response to this issue, a design concept of enhanced regional electric potential difference (EREPD) is proposed to modulate the interaction of nanofillers with other components in the composite polymer solid-state electrolytes (CPSEs). While ensuring the periodic structure of the graphdiyne (GDY) backbone, methoxy-substituted GDY (OGDY) is prepared by an asymmetric substitution strategy, which increases the electric potential differences within each repeating unit of GDY. The staggered distributed electron-rich regions and electron-deficient regions on the two-dimensional plane of OGDY increase the free Li + concentration through Lewis acid–base pair interaction. The adjacent ERRs and EDRs form uniformly distributed EREPDs, creating a continuous potential gradient that synergistically facilitates the efficient migration of Li + . Impressively, the OGDY/poly(ethylene oxide) (PEO) exhibits a high ionic conductivity (1.1 × 10 –3 S cm −1 ) and ion mobility number (0.71). In addition, the accelerated Li + migration promotes the formation of uniform and dense SEI layers and inhibits the growth of lithium dendrites. As a proof of concept, Li||Li symmetric cell and Li||LiFePO 4 full cell and pouch cell assembled with OGDY/PEO exhibit good performance, highlighting the effectiveness of our EREPD design strategy for improving CPSEs performance.

Developing solid-state electrolytes with good compatibility for high-voltage cathodes and reliable operation of batteries over a wide-temperature-range are two bottleneck requirements for practical applications of solid-state metal batteries (SSMBs). Here, an in situ quasi solid-state poly-ether electrolyte (SPEE) with a nano-hierarchical design is reported. A solid-eutectic electrolyte is employed on the cathode surface to achieve highly-stable performance in thermodynamic and electrochemical aspects. This performance is mainly due to an improved compatibility in the electrode/electrolyte interface by nano-hierarchical SPEE and a reinforced interface stability, resulting in superb-cyclic stability in Li || Li symmetric batteries ( > 4000 h at 1 mA cm −2 /1 mAh cm −2 ; > 2000 h at 1 mA cm −2 /4 mAh cm −2 ), which are the same for Na, K, and Zn batteries. The SPEE enables outstanding cycle-stability for wide-temperature operation (15–100 ° C) and 4 V-above batteries (Li || LiCoO 2 and Li || LiNi 0.8 Co 0.1 Mn 0.1 O 2 ). The work paves the way for development of practical SSMBs that meet the demands for wide-temperature applicability, high-energy density, long lifespan, and mass production.

Tin phosphide (Sn 4 P 3 ) has arisen to be an anode material toward lithium-ion batteries (LIBs) with great potential for its high theoretic Li-storage capacity. Nevertheless, unavoidable capacity fading as well as poor rate capability have severely hindered the extended application of Sn 4 P 3 . In this paper, a hierarchical hybrid (Sn 4 P 3 -NC) has been fabricated by an easy freeze-drying followed by an annealing and phosphorization treatment. In this hybrid, Sn 4 P 3 nanoparticles are well encapsulated into honeycomb-like nitrogen-doped carbon frameworks. Porous carbon provides multiple electron expressway and robust mechanical support. Furthermore, Sn 4 P 3 nanoparticles are well confined in carbon matrix so as to effectively alleviate the volume expansion. Having profited from the desirable nanostructures and significantly enhanced synergetic effect, Sn 4 P 3 -NC as an anode for LIB achieves an extremely improved electrochemical property . A high capacity of ~881 mAh g −1 could be retained after 150 cycles at 100 mA g −1 and an enhanced rate and cycle performance with the discharge capacity of ~507 mAh g −1 at 1000 mA g −1 through 400 cycles is also exhibited.

Li-S batteries have been regarded as one of the most prospective energy-storage systems because of its high-energy-density. To suppress the shuttling effect of dissolved lithium polysulfides, different mass ratios petal-like nickel hydroxide nanosheets (NHN) decorated reduced graphene oxide (rGO) materials are synthesized in this study using a one-step hydrothermal method and applied modified separators in Li-S batteries. With up to 73.5 wt% of sulfur content in the cathode, the optimized sample (the mass ratio of graphene oxide to nickel nitrate is 1:9) enables discharge capacities up to 1579 mAh g −1 at 0.2 C (the areal sulfur loading is 5 mg cm −2 ). The cell also exhibits a retention of 840 mAh g −1 in specific capacity after 200 cycles, exhibiting higher utilizations and better cycling stabilities for Li-S batteries. Electrochemical measurements and density functional theory (DFT) calculations prove that NHN plays a critical role in promoting the redox reaction kinetics of Li-S batteries, and the high conductivity of rGO enhances the electrochemical function of NHN. This study provides a low cost approach for the developments of modified separators in future practical Li-S batteries.
