Rechargeable aluminum ion batteries (RAIBs) exhibit great potential for next-generation energy storage systems owing to the abundant resources, high theoretical volumetric capacity and light weight of the Al metal anode. However, the development of RAIBs based on Al metal anodes faces challenges such as dendrite formation, self-corrosion, and volume expansion at the anode/electrolyte interface, which needs the rational design of an aluminum anode for high-performance RAIBs. This work proposes a novel and low-cost strategy by utilizing an alloy electrodeposition method in a low-temperature molten salt system to fabricate an aluminum–tin (AlSn) alloy coating layer on copper foil as the anode for RAIBs, which successfully addresses the issues of dendrite formation and corrosion at the anode/electrolyte interface. The artificial AlSn alloy layer could enhance the active sites for metal Al homogeneous deposition and effectively retard the dendrite formation, which was verified by an in situ optical microscopy study. The symmetric AlSn@Cu cell demonstrates a low average overpotential of ∼38 mV at a current density of 0.5 mA cm−2 and a long-term lifespan of over 1100 h. Moreover, the AlSn@Cu//Mo6S8 full cells deliver a high capacity of 114.9 mA h g−1 at a current density of 100 mA g−1 and maintain ultra-stable cycling stability even over 1400 cycles with a ∼100% coulombic efficiency (CE) during the long-term charge/discharge processes. This facile alloy electrodeposition approach for designing high-performance Al-based anodes provides insights into the understanding of artificial interface chemistry on Al-based anodes and potentially accelerates the design of high-performance RAIBs.

Currently, silicon-based anode is one of the most promising anode materials which can be applied in next-generation lithium-ion batteries. However, the high activity of electrode-electrolyte interface and low electronic conductivity of Si anode during the cycling process greatly limits its large-scale application. Al is the metallic current collector known to promote electronic conductivity and lithium-ion transfer with low cost. However, to our knowledge, scalable interface engineering incorporating Al with carbonized polymer has not been reported. Herein, a polyacrylonitrile (PAN) and aluminum metal dual functionalization interconnected network is achieved via a simple sol-gel method followed by high-temperature calcination to obtain a stable solid electrolyte interphase (SEI) while allowing fast Li + transmission. The calculated diffusion energy barrier for lithium ions in Al is 0.2198 eV, significantly lower than that in Cu and Fe. Benefiting from the enhanced interfacial protection and kinetics of Si with polyacrylonitrile/Al, the prepared Si@Al@CPAN anode exhibits high lithium storage capacity (2034.90 mAh·g -1 after 150 cycles at 0.84 A·g -1 ). At the same time, the prepared Si@Al@CPAN anode outperforms the pure Si anode in rate performance at 12.6 A g -1 (1116.75 mAh·g -1 vs. 2.84 mAh·g -1 ). The present work delivers new design ideas for high-performance Si anode with the multi-functionalization interface.

A honeycomb-like porous self-supporting Ni-Al(G) electrode was successfully prepared by low-pressure cold spraying combined with heat treatment. The main components of the electrode were Ni and NiAl. Graphene was uniformly dispersed throughout the electrode, exhibiting a 3-D distribution, which increased the active site of electrode and improved the electron exchange rate. The electrochemical properties of the Ni-Al(G) electrode were characterized using 6 M KOH. As a result, the Ni-Al(G) electrode requires only an overpotential of 130 mV to achieve a current density of 100 mA cm −2 , and a Tafel slope of 35.5 mV dec −1 . In addition, the electrode exhibited excellent stability. The addition of graphene and the honeycomb-like porous structure of the Ni-Al(G) electrode resulted in an excellent hydrogen evolution activity. This study provides a simple and rapid technique for building high-performance, low-cost, and industrially available electrodes for the efficient alkaline HER.

Aluminum metal batteries (AMBs), as a next-generation green energy system, have garnered significant attention due to their inherent safety, low cost, and environmental benignity. However, non-uniform aluminum deposition and dendrite growth during cycling lead to rapid battery failure, resulting in resource waste and environmental pollution. To enhance resource utilization and achieve aluminum metal batteries with high efficiency and long cycle life, this study proposes an eco-friendly soft ZnP-H2Im glass film fabricated via a melt-quenching process as a protective layer for the aluminum anode, which minimizes the use of hazardous substances and improves process sustainability. This material combines excellent mechanical flexibility, chemical stability, and ion transport regulation (via its sub-nanochannels), enabling homogeneous AlCl4− and Al2Cl7− migration and promoting uniform aluminum nucleation and deposition. As a result, Al//Al symmetric cells based on soft ZnP-H2Im-protected Al achieve record-breaking cycle lives of more than 10 000 hours at various areal capacities and current densities, far surpassing those of unmodified systems. In addition, after coupling the soft ZnP-H2Im-protected Al with two organic cathodes, tetrachlorobenzoquinone (TCQ) and 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ), the AMBs demonstrate high capacity, high reversibility, and high stability, with a capacity retention of 95% after 200 cycles and 80% after 220 cycles, respectively. This study not only advances interfacial engineering for AMBs but also provides a potential reference for extending this eco-friendly coordination polymer vitrification strategy to other metal anode systems, providing a transformative approach for developing high-performance secondary batteries with enhanced resource efficiency.

Great progress has been made in the development of cathode materials for Al-metal batteries . However, the in-depth study of Al anodes, especially the battery instability caused by Al dendrite growth, has not received much attention. In this work, we have identified the in-situ formation of Al dendrite growth, which is proved to bottleneck the practical use of Al-metal batteries. The dendrite formation severely affects battery performance, such as voltage and efficiency fluctuations, unstable cycling, etc. To further demonstrate the detailed growing process of dendrites, we make a comprehensive investigation into the interfacial chemistry of Al anode. We have found that the naturally formed Al 2 O 3 surface film is dissolved in the ionic liquid electrolyte during Al plating, accompanied by the formation of solid-electrolyte interphase containing Al-Cl and Al-O like species on the anode surface before dendrite growth. To suppress this dendrite growth, we propose the use of porous Al, which provides a homogeneous ion flux and decreases the local current density. As a result, the porous anode maintains stable cycling over a wide range of current densities and areal capacities. The Al-graphite battery shows stable cycling up to 18000 times without capacity decay. This work suggests the significance of suppressing dendrite growth for the real applications and commercialization of Al-metal batteries and will draw attention to the battery design from the anode side .

Aluminum–metal batteries show great potential as next-generation energy storage due to their abundant resources and intrinsic safety. However, the crucial limitations of metallic Al anodes, such as dendrite and corrosion problems in conventional aluminum–metal batteries, remain challenging and elusive. Here, we report a novel electrodeposition strategy to prepare an optimized 3D Al anode on carbon cloth with an uniform deposition morphology, low local current density, and mitigatory volume change. The symmetrical cells with the 3D Al anode show superior stable cycling (>450 h) and low-voltage hysteresis (~170 mV) at 0.5 mA cm −2 . High reversibility (~99.7%) is achieved for the Al plating/stripping. The graphite | | Al-4/CC full batteries show a long lifespan of 800 cycles with 54 mAh g −1 capacity at a high current density of 1000 mA g −1 , benefiting from the high capacitive-controlled distribution. This study proposes a novel strategy to design 3D Al anodes for metallic-Al-based batteries by eliminating the problems of planar Al anodes and realizing the potential applications of aluminum–graphite batteries.

Due to strong anti-poisoning ability, good emission stability, high emission current density, lanthanum hexaboride (LaB 6 ) and cerium hexaboride (CeB 6 ) have been maturely applied in electron emission emitter. In this paper, a new manufacturing method for LaB 6 (or CeB 6 ) powder was proposed by using La 2 O 3 (or CeO 2 ), B 4 C, and Al as raw materials. After high-temperature reaction in the range of 1673–1773 K and the following alkaline leaching at 90°C, LaB 6 or CeB 6 powder with particle size of about 10 μm was obtained. Furthermore, by Al metal flux method, the obtained powder was used to manufacture single crystal block with size of several millimeters.

High-performance nanofiltration membrane is of great importance to alleviate the worldwide freshwater crisis. Recent studies have shown that the performance of nanofiltration membranes can be enhanced by optimizing the properties of the substrates. Substrates with large pores are favorable to mass transfer but difficult to prepare highly selective polyamide layers on them by interfacial polymerization reaction. Here we employed porous two-dimensional (2D) aluminum-metal organic framework (Al-MOF) nanosheets to tune the commercial Nylon microfiltration substrate, and then prepared polyamide nanofiltration membranes by interfacial polymerization. 2D Al-MOF nanosheets were chosen for the tuning material except for their obvious advantages of easy synthesis and structural stability, the most important thing was their high porosity, which provided additional water transport channels. The morphologies as well as the separation properties were analyzed systematically. The best-performing Nylon-2.5 TFC membrane achieved an ultrahigh permeability (42.4 L m −2 h −1 bar −1 ), 13 times that of a control (PES-0) TFC membrane prepared on commercial PES substrate under the same interfacial polymerization conditions while ensuring the high rejection of Na 2 SO 4 (97.0%). Our work provides insights for optimizing substrate properties to prepare high-performance nanofiltration membranes.

Aluminum-ion (Al-ion) batteries are emerging as promising candidates for large-scale energy storage due to their low cost. However, the poor cycling stability of the aluminum (Al) metal anode, which arises from more severe non-planar deposition than those of the other metals, particularly at high current densities, limits their practical applications. Herein, we applied classical metal electrodeposition theory to better understand aluminum deposition behavior and proposed a simple and practical approach to achieve uniform electrodeposition of aluminium. This approach involved regulating the ratio of exchange current density (i0) to limiting current density (iL), which serves as a descriptor for the metal deposition process. The regulation was achieved by applying an electron-insulating polydimethylsiloxane (PDMS) coating. By carefully tuning the coating thickness, we were able to regulate the exchange current density, optimizing the balance between mitigating interphase reactions and maintaining efficient mass transport. As a result, a stable Al metal anode reaction was obtained over 2800 hours under the exceptionally large current density of 5 mA cm−2 and a high deposition capacity of 5 mA h cm−2. The full cell with an artificial graphite cathode delivered a stable discharge capacity of 65 mA h g−1 and a high CE of 99.5%, with no apparent capacity or CE decay over 2500 cycles. This work presents a new strategy for regulating electrodeposition in Al metal anodes and demonstrates an electrodeposition principle for metal anode batteries.

Constructing robust anode with strong aluminophilicity and rapid desolvation kinetics is essential for achieving high utilization, long-term durability, and superior rate performance in Al metal-based energy storage, yet remains largely unexplored. Herein, molybdenum nanoparticles embedded onto nitrogen-doped graphene (Mo@NG) are designed and prepared as Al host to regulate the deposition behavior and achieve homogeneous Al plating/stripping. The monodispersed Mo nanoparticles reduce the desolvation energy barrier and promote the deposition kinetics of Al. Additionally, Mo nanoparticles act as aluminophilic nucleation sites to minimize the Al nucleation overpotential, further guiding uniform and dense Al deposition. As a result, the dual-functional Mo@NG endows Al anodes with low voltage hysteresis, reversible Al plating/stripping with high coulombic efficiency, and excellent high-rate capability under 5 mA cm −2 . Moreover, the as-designed Al metal full batteries deliver a high capacity retention of 92.8% after 3000 cycles at 1 A g −1 . This work provides an effective solution to optimize the electrochemical properties of Al metal anode from the perspective of desolvation and deposition reactions, towards the development of high-safety and long-cycling aluminum-ion batteries.

Electrolytes are highly important for aqueous Al ion batteries (AAIBs). However, Al metal anode usually has poor reversibility of plating/tripping, resulting in low Coulombic efficiency (CE) and poor cycling stability by using traditional Al ion electrolyte. Herein, a novel type of aqueous Al ion electrolyte with polyethylene glycol (PEG) as the primary skeleton for solvated Al ions is proposed, named as PEG-Al@H. Outstandingly, an Al electrolyte interface (AEI) is generated on the Al metal surface during galvanostatic charging process by polymerization of PEG. It is proved that AEI, acting as the protective layer, effectively mitigates the side reaction caused by the rapid kinetic in aqueous electrolyte and prevents Al metal anode from deeply corroding. Moreover, PEG disrupts the hydrogen bond of the solvent in the electrolyte, extending the working temperature of AAIBs. The design that a full-cell consisting of PEG-Al@H as the electrolyte, potassium manganese hexacyanoferrate as the cathode, Al metal as anode can run over 20 000 cycles at 500 mA g −1 , with an average CE higher than 95%. More importantly, even at −5 °C, for the first time, an initial capacity of 16 mAh in a pouch-cell is achieved and maintain roughly 87% of capacity after 5500 cycles.

The application needs of small electronic devices and large-scale power grid storage continuously promote the development of a new battery energy system. Rechargeable metal batteries based on aluminum (Al) are of enormous potential due to the abundant Al reserves, the trivalent charge carrier, high theoretical specific capacity (2980 mAh/g), and volumetric energy density (8046 mAh/cm 3 ). However, the passivating oxide layer on the surface of the Al anode blocks the migration of electrons and ions, resulting in the operation difficulty and irreversibility of aluminum-based batteries. Herein we treated Al anode with a deep eutectic solution (DES) and constructed stable solid interface interphase on its surface, which can effectively prevent surface passivation , improve the chemical properties of the interface, promote ion transfer, and enable aqueous Al batteries with superior electrochemical performance . The assembled symmetric cells with treat Al (TAl) can cycle for more than 300 h with a low overpotential (~0.2 V). The TAl anode coupling with the FPB cathode material to assemble the full cells based on the aqueous electrolyte system can deliver a high discharge capacity of 85 mAh/g and exhibit capacity retention of 58 mAh/g after 150 cycles and an average coulombic efficiency of 97.1% at a current density of 100 mA/g. This work provides a novel surface modification strategy of Al metal anode and demonstrates high stability and cost-effective aqueous Al metal battery system, which suggest the significance for the commercialization of Al-metal batteries and their applications in large-scale energy store.
