Aluminum batteries employing organic electrode materials present an appealing avenue for sustainable and large‐scale energy storage. Nevertheless, conventional organic materials encounter limitations due to their restricted active sites, known instability, and sluggish redox kinetics. In this study, a redox‐active covalent organic framework supported by CNT is reported, enriched with substantial C═O groups, as an advanced cathode material for Al‐organic batteries. Theoretical simulation and ex situ analysis unveil the pivotal roles of C═O groups in effectively storing AlCl2+. As a result, Al batteries with the organic cathode exhibit a specific capacity of 290 mAh g−1 at 0.2 A g−1 and outstanding rate performance. Furthermore, it retains a reversible capacity of 170 mAh g−1 even after 32 000 cycles at 10 A g−1 and attains an energy density of 389 Wh kg−1. The remarkable performance stems not only from the abundant C═O and C─N groups enabling the storage of multiple AlCl2+ by the favorable pseudocapacitive process, but also from the synergistic interplay between the robust COF network and the conductive CNT channels that significantly enhances structural stability and accelerates ion/electron diffusion. This work stands to inspire further research in the pursuit of stable organic cathodes, fostering designs with plentiful accessible redox‐active sites to boost energy storage capabilities.

The interrelated side reactions and dendrites growth severely destabilize the electrode/electrolyte interfaces, resulting in the difficult application of aqueous Zn ion batteries (AZIBs). Hydrophobic protective layer possesses natural inhibition ability for side reactions. However, the conventional protective layer with plane structure is difficult to attain joint regulation of side reaction and Zn nucleation. Herein, a novel three‐dimensional (3D) electrically conductive and hydrophobic (3DECH) interface is elaborated to enable stable Zn anode. The as‐prepared 3DECH interface presents a uniform 3D morphology with hydrophobic property, large specific surface area, abundant zincophilic sites, and excellent electroconductivity. Therefore, the 3DECH interface achieves uniform nucleation and dendrite‐free deposition from synergetic benefits: (1) increased nucleation sites and reduced local current density through the special 3D structure and (2) uniform electric potential distribution and rapid Zn2+ transport due to the electroconductive alloy chemistry, thus coupling the hydrophobic property to obtain a highly reversible Zn anode. Consequently, the modified anode achieves a superior coulombic efficiency of 99.88% over 3500 cycles, and the pouch cells using modified anode and LiMn2O4 (LMO) cathode retain a capacity of 84 mAh g−1 after 700 cycles at a reasonable depth discharge of 36%, without dendrite piercing and "dead Zn."

The Zn//V2O5 system not only faces the incontrollable growth of zinc (Zn) dendrites, but also withstands the cross‐talk effect of by‐products produced from the cathode side to the Zn anode, inducing interelectrode talk and aggravating battery failure. To tackle these issues, we construct a rapid Zn2+‐conducting hydrogel electrolyte (R‐ZSO) to achieve Zn deposition modulation and side reaction inhibition in Zn//V2O5 full cells. The polymer matrix and BN exhibit a robust anchoring effect on SO42−, accelerating Zn2+ migration and enabling dense Zn deposition behavior. Therefore, the Zn//Zn symmetric cells based on the R‐ZSO electrolyte can operate stably for more than 1500 h, which is six times higher than that of cells employing the blank electrolyte. More importantly, the R‐ZSO hydrogel electrolyte effectively decouples the cross‐talk effects, thus breaking the infinite loop of side reactions. As a result, the Zn//V2O5 cells using this modified hydrogel electrolyte demonstrate stable operation over 1,000 cycles, with a capacity loss rate of only 0.028 % per cycle. Our study provides a promising gel chemistry, which offers a valuable guide for the construction of high‐performance and multifunctional aqueous Zn‐ion batteries. [ABSTRACT FROM AUTHOR]

Zinc‐bromine batteries (ZBBs) have emerged as a compelling solution for large‐scale energy storage, yet they confront significant technical challenges impeding widespread commercialization. The electrochemical processes within ZBBs rely on a stoichiometric mechanism, where the bromine reaction at the cathode drives the zinc plating reaction on the anode. However, the sluggish electrochemical kinetics of Br2/Br− redox reactions lead to substantial electrochemical polarization, resulting in interruptions in zinc plating and significant voltage losses in ZBBs. This study introduces a new solution to address these challenges by leveraging carbon nanofiber decorated with tin nanoparticles as an efficient catalyst. The catalyst serves to enhance the Br2/Br– redox reaction, effectively reducing voltage losses in ZBBs. When implemented in static ZBB configurations, the Sn/CNF catalysts demonstrate exceptional long‐term stability, achieving an impressive 3000 cycles with minimal voltage loss. In contrast, ZBBs utilizing SnO2 based catalysts experience a substantially higher voltage loss of 736 mV, along with limited and unstable cycling performance. These findings signify a promising approach for the development of catalytic electrodes, paving the way for high‐performance ZBBs with improved efficiency and cycling durability.

Aims: Dexmedetomidine (DEX) has been reported to alleviate hypoxic–ischemic brain damage (HIBD) in neonates. This study aimed to investigate whether DEX improves cognitive impairment by promoting hippocampal neurogenesis via the BDNF/TrkB/CREB signaling pathway in neonatal rats with HIBD. Methods: HIBD was induced in postnatal day 7 rats using the Rice‐Vannucci method, and DEX (25 μg/kg) was administered intraperitoneally immediately after the HIBD induction. The BDNF/TrkB/CREB pathway was regulated by administering the TrkB receptor antagonist ANA‐12 through intraperitoneal injection or by delivering adeno‐associated virus (AAV)‐shRNA‐BDNF via intrahippocampal injection. Western blot was performed to measure the levels of BDNF, TrkB, and CREB. Immunofluorescence staining was utilized to identify the polarization of astrocytes and evaluate the levels of neurogenesis in the dentate gyrus of the hippocampus. Nissl and TTC staining were performed to evaluate the extent of neuronal damage. The MWM test was conducted to evaluate spatial learning and memory ability. Results: The levels of BDNF and neurogenesis exhibited a notable decrease in the hippocampus of neonatal rats after HIBD, as determined by RNA‐sequencing technology. Our results demonstrated that treatment with DEX effectively increased the protein expression of BDNF and the phosphorylation of TrkB and CREB, promoting neurogenesis in the dentate gyrus of the hippocampus in neonatal rats with HIBD. Specifically, DEX treatment significantly augmented the expression of BDNF in hippocampal astrocytes, while decreasing the proportion of detrimental A1 astrocytes and increasing the proportion of beneficial A2 astrocytes in neonatal rats with HIBD. Furthermore, inhibiting the BDNF/TrkB/CREB pathway using either ANA‐12 or AAV‐shRNA‐BDNF significantly counteracted the advantageous outcomes of DEX on hippocampal neurogenesis, neuronal survival, and cognitive improvement. Conclusions: DEX promoted neurogenesis in the hippocampus by activating the BDNF/TrkB/CREB pathway through the induction of polarization of A1 astrocytes toward A2 astrocytes, subsequently mitigating neuronal damage and cognitive impairment in neonates with HIBD.

The practical application of AZIBs is hindered by problems such as dendrites and hydrogen evolution reactions caused by the thermodynamic instability of Zinc (Zn) metal. Modification of the Zn surface through interface engineering can effectively solve the above problems. Here, sulfonate‐derivatized graphene–boronene nanosheets (G&B‐S) composite interfacial layer is prepared to modulate the Zn plating/stripping and mitigates the side reactions with electrolyte through a simple and green electroplating method. Thanks to the electronegativity of the sulfonate groups, the G&B‐S interface promotes a dendrite‐free deposition behavior through a fast desolvation process and a uniform interfacial electric field mitigating the tip effect. Theoretical calculations and QCM‐D experiments confirmed the fast dynamic mechanism and excellent mechanical properties of the G&B‐S interfacial layer. By coupling the dynamics‐mechanics action, the G&B‐S@Zn symmetric battery is cycled for a long‐term of 1900 h at a high current density of 5 mA cm−2, with a low overpotential of ≈30 mV. Furthermore, when coupled with the LMO cathode, the LMO//G&B‐S@Zn cell also exhibits excellent performance, indicating the durability of the G&B‐S@Zn anode. Accordingly, this novel multifunctional interfacial layer offers a promising approach to significantly enhance the electrochemical performance of AZIBs. [ABSTRACT FROM AUTHOR]

Zinc‐bromine flow batteries (ZBFBs) are promising candidates for the large‐scale stationary energy storage application due to their inherent scalability and flexibility, low cost, green, and environmentally friendly characteristics. ZBFBs have been commercially available for several years in both grid scale and residential energy storage applications.

Dual‐ion batteries (DIBs) is a promising technology for large‐scale energy storage. However, it is still questionable how material structures affect the anion storage behavior. In this paper, we synthesis graphite with an ultra‐large interlayer distance and heteroatomic doping to systematically investigate the combined effects on DIBs. The large interlayer distance of 0.51 nm provides more space for anion storage, while the doping of the heteroatoms reduces the energy barriers for anion intercalation and migration and enhances rapid ionic storage at interfaces simultaneously. Based on the synergistic effects, the DIBs composed of carbon cathode and lithium anode afford ultra‐high capacity of 240 mAh g−1 at current density of 100 mA g−1. Dual‐carbon batteries (DCBs) using the graphite as both of cathode and anode steadily cycle 2400 times at current density of 1 A g−1. Hence, this work provides a reference to the strategy of material designs of DIBs and DCBs. [ABSTRACT FROM AUTHOR]

Heterostructures with interfacial effects have exhibited great potential for improving the electrochemical kinetics of electrode materials. However, the application of heterostructures is hampered by complicated synthesis parameters and numerous single components. Herein, a multiple‐templating synthesis strategy is proposed to improve the interfacial effect of heterojunction composites, mitigate volume variation upon lithiation/de‐lithiation, and increase interfacial compatibility with poly‐oxyethylene‐based (PEO‐based) electrolytes. Benefiting from the structural and compositional superiorities, the novel NiS/SnO2/MOF (NSM) electrode achieves superior electrochemical performance with exceptional specific capacity, outstanding rate capability and ultralong cyclability. As a result of the compatibility between organic components and the porous properties of metal organic frameworks (MOFs), the NSM electrode exhibits greater interfacial compatibility with PEO‐based solid‐state electrolytes. This work not only describes a meticulous protocol for heterostructured high‐performance electrode materials, but also provides a new insight to enhance the connectivity between the interfaces of solid‐state batteries.

Background: Distant metastasis is a sign of poor prognosis for cancer patients. Extrahepatic liver cancer metastases commonly spread to the lung. Remodelling of the metastatic microenvironment is essential for tumour metastasis. Neutrophil‐associated metastatic microenvironment contributes to the early metastatic colonisation of cancer cells in the lung. Method: The lung metastasis models were constructed via treated cancer cells by tail vein injection into mice. And samples of lung were harvested at the indicated time to analyze tumor growth and immune cells in the microenvironment. Tumors and lung metastasis specimens were obtained via surgical operations for research purposes. Neutrophils were obtained from peripheral blood of patients with liver cancer or healthy donors (HD). Results: Hepatocellular carcinoma cells reduce the secretion of histidine‐rich glycoprotein (HRG), regulate the recruitment and activation of neutrophils in the metastatic microenvironment and promote the production of neutrophil extracellular traps (NETs), thereby promoting liver cancer lung metastasis. HRG binds to FCγR1 on the neutrophil membrane while inhibiting PI3K and NF‐κB activation, thereby reducing IL‐8 secretion to reduce neutrophil recruitment. Meanwhile, HRG inhibited IL8‐MAPK and NF‐κB pathway activation and ROS production, resulting in reduced NETs formation. Conclusions: Our study reveals that liver cancer regulates neutrophil recruitment and NETs formation in the metastatic microenvironment by reducing HRG secretion, thereby promoting tumour lung metastasis. The results of this study will contribute to the development of possible strategies for treating metastases. [ABSTRACT FROM AUTHOR]

The commercial application of lithium (Li) metal anode is hindered by the growth of Li dendrites. Here, we develop a multidimensional composite structure composed of Co3O4/NiO heterojunction particles and reduced graphene oxide (rGO) nanosheets, that allows Li to nucleate and deposit selectively in one direction. Among, two transition metal oxides (TMOs) without lithiophilicity are transformed into lithiophilic species due to the rich phase boundaries and high Li adsorption energies on interfaces, which can provide uniform active sites and reduce nucleation overpotential for Li deposition. Meanwhile, the rGO substrate with high electrical conductivity and large specific surface area can form a conductive network between TMOs and alleviate volume expansion caused by Li deposition. Benefitting from the synergistic effect of the heterojunctions and carbon substrate, the Co3O4/NiO‐rGO regulates the local current density and enables the dendrite‐free Li plating/stripping behavior. At a current density of 1 mA cm−2, the Li metal anode with the Co3O4/NiO‐rGO host exhibits remarkable electrochemical performance, consistently maintaining high Coulombic efficiency (>93.8%) over 1000 cycles. Additionally, the full cells matched with LiFePO4 cathode also display high rate capability of 130 mAh g−1 at 1 C and stable cycling life over 500 cycles. [ABSTRACT FROM AUTHOR]

Superior lithophilicity for the 3D host is essential to enable both uniform molten lithium (Li) infusion during synthesis and a low Li nucleation barrier during cycling. The wetting behavior between the host surface and molten Li can be reasonably predicted by the typical Wenzel model. Herein, inspired by the model, a lotus‐leaf‐like carbon nanotube (CNT)/NiO spheres hybrid structure is employed to improve the wettability and regulate Li plating/stripping. First, the CNTs interweave to form a highly conductive and robust sponge with accelerated Li+ transport and reinforced stability. Second, the embedded NiO microspheres possess the Li‐active nature. More importantly, the surface roughness caused by nano‐sized protuberances over its surface further stronger the lithiophilicity. By the in situ optical microscope and calculations, this multistage structure is proven to homogenize the Li deposition and inhibit dendrite growth. As a result, the composite anode enables excellent cycling performance at both symmetric and full cells. This design of micro/nanostructured host provides a new perspective on the development of an excellent wettable host for Li‐metal anode. [ABSTRACT FROM AUTHOR]

Li‐O2 batteries are promising energy storage devices with ultra‐high theoretical energy density. However, in practice they show severe capacity fading and limited cycle life, meaning that more suitable electrolytes are urgently needed. Here, solvents are combined with high donor number and low donor number, and a Li salt to produce a new local strong solvation effect electrolyte. High discharge capacity and good cycling performance are achieved when the optimized electrolyte is used in a Li‐O2 battery. The optimized electrolyte inhibits side reactions within the battery and facilitates stable solid electrolyte interphase film formation on the surfaces of Li anode. This work opens a new route for the design of high‐performance electrolytes to increase both capacity and cycle life of Li‐O2 batteries. [ABSTRACT FROM AUTHOR]

The present study reports a one‐step synthesis method for the preparation of cationic gold nanoclusters (Au NCs). Polyethyleneimine (PEI), a positively charged hyperbranched polyamine, was selected as the capping reagent. Glutathione showed a synergistic effect on the formation of the small size of cationic Au NCs. The prepared cationic Au NCs have a size less than 2 nm and carry a positive charge in solution with pH less than 11. The cationic PEI–Au NCs‐triggered luminol chemiluminescence (CL) reactions showed slow and intense CL profiles. The maximum CL intensity can be obtained within 10 min and the CL signal maintained almost the same within 30 min. A linear increase of CL intensity was observed in the presence of an increasing concentration of cationic Au NCs ranging from 0.030 μM to 15 μM. The linear response of the cationic Au NCs in the CL reaction and the glow‐type CL profile make the proposed CL reaction have broad application prospects in the field of biological analysis and CL imaging.

Ionic liquid gel‐polymer electrolytes (GPEs) have attracted increasing attention, owing to their merits of safety and reliability. However, the high viscosity of ionic liquid requires better transmission channels for the polymer. Exploration of ionic liquid GPEs with high ionic conductivity and excellent transmission channels is a possible strategy to optimize the practicability of sodium‐based technology. A flexible GPE with high ionic conductivity and excellent transmission channels is synthesized with poly(vinylidene fluoride‐co‐hexafluoropropylene) (PVDF−HFP) as the base material blended with the water‐insoluble ionic liquid N‐methyl‐N‐butyl piperidine difluoromethylimide ([PP14][TFSI]) by using a phase‐inversion technique. A polydopamine coating is then introduced into the GPE to improve wettability and compatibility. The thermal decomposition temperature of the prepared gel‐polymer films is greater than 450 °C. Our activated GPE achieves good safety, a wide electrochemical window, and high ionic conductivity. When testing a sodium‐ion battery with Prussian blue as the cathode, the batteries show good cycling performance. Our results suggest that the as‐prepared GPE can be efficiently and safely used in sodium‐ion batteries. [ABSTRACT FROM AUTHOR]

The exploration of anode materials with enhanced electronic/ionic conductivity and structural stability is beneficial for the development of sodium‐ion batteries. Herein, a simple solution‐derived method is demonstrated to fabricate porous VO2 microsphere composite with a graphene‐wrapped structure (VO2/G). When used as the anode material for sodium‐ion batteries, the VO2/G electrode delivers a high reversible specific capacity (373.0 mAh g−1), great rate capability (138.8 mA h g−1 at 24.0 A g−1, ≈21 s per charge/discharge), and excellent long‐cycling performance (95.9 % capacity retention for 3600 cycles at 2.0 A g−1). The outstanding electrochemical property of VO2/G is mainly attributed to its unique graphene‐wrapped porous structure and the pseudocapacitive‐dominated feature. In addition, the sodium‐ion storage mechanism of VO2/G is investigated by various ex‐situ characterization techniques. During the first sodiation process, the sodium‐ion appears to partially reduce VO2/G and form metallic vanadium, sodium oxide, and amorphous sodium vanadium. This work provides new fundamental information for the design and application of vanadium oxides for energy storage system. I want to see it painted, painted black: graphene‐wrapped porous VO2 microspheres are successfully synthesized. As anode for sodium‐ion batteries, the material delivers excellent cycling stability and rate performance. [ABSTRACT FROM AUTHOR]

Abstract: Lithium–sulfur (Li–S) batteries, as one of the most important candidates of next‐generation batteries, are famous for high energy density, low cost, and environmental friendly benignity. However, issues originating from polysulfide shuttle of common liquid electrolytes (e.g., capacity fade, poor cycle life, and safe issue) have hindered the applications of Li–S batteries in various occasions. This review summarizes the main efforts in the electrolytes of Li–S batteries, including liquid, solid state, and hybrid electrolyte systems. The development of functional electrolytes for Li–S batteries is hopeful to alleviate the problems Li–S batteries faced today. The liquid electrolytes circumvent the polysulfide shuttle and the resultant problems by utilizing different functional solvents, lithium salts, and additives. Solid‐state electrolytes as promising electrolytes are optimized to enhance the ionic conductivity at room temperature and decrease the interfacial resistance. Hybrid electrolytes that consist of two or more single electrolytes may be considered as unique categories because they have the potential advantages than the single electrolyte systems. Challenges and perspectives of Li–S electrolytes are also proposed based on the requirement for high‐performance Li–S batteries. [ABSTRACT FROM AUTHOR]

Abstract: Sodium‐ion batteries (SIBs) are considered to be a promising alternative for large‐scale electricity storage. However, it is urgent to develop new anode materials with superior ultralong cycle life performance at high current rates. Herein, a low‐cost and large‐scalable sulfur‐doped carbon anode material that exhibits the best high‐rate cycle performance and the longest cycle life ever reported for carbon anodes is developed. The material delivers a reversible capacity of 142 mA h g−1 at a current rate up to 10 A g−1. After 10 000 cycles the capacity is remained at 126.5 mA h g−1; 89.1% of the initial value. Density functional theory computations demonstrate that the sulfur‐doped carbon has a strong binding affinity for sodium which promotes sodium storage. Meanwhile, the kinetics analysis identifies the capacitive charge storage as a large contributor to sodium storage, which favors ultrafast storage of sodium ions. These results demonstrate a new way to design carbon‐based SIBs anodes for next‐generation large‐scale electricity storage. [ABSTRACT FROM AUTHOR]

Rechargeable high‐energy lithium–sulfur batteries suffer from rapid capacity decay and poor rate capability due to intrinsically intermediate polysulfides' shuttle effect and sluggish redox kinetics. To tackle these problems simultaneously, a layer‐by‐layer electrode structure is designed, each layer of which consists of ultrafine CoS2‐nanoparticle‐embedded porous carbon evenly grown on both sides of reduced graphene oxide (rGO). The CoS2 nanoparticles derived from metal–organic frameworks (MOFs) have an average size of ≈10 nm and can facilitate the conversion between Li2S6 and Li2S2/Li2S in the liquid electrolyte by a catalytic effect, leading to improved polysulfide redox kinetics. In addition, the interconnected conductive frameworks with hierarchical pore structure afford fast ion and electron transport and provide sufficient space to confine polysulfides. As a result, the layer‐by‐layer electrodes exhibit good rate capabilities with 1180.7 and 700 mAh g−1 at 1.0 and 5.0 C, respectively, and maintain an impressive cycling stability with a low capacity decay of 0.033% per cycle within ultralong 1000 cycles at 5.0 C. Even with a high sulfur loading of 3.0 mg cm−2, the electrodes still show high rate performance and stable cycling stability over 300 cycles. [ABSTRACT FROM AUTHOR]

Herein, two strategies are simultaneously used to synthesize the hollow carbon‐coated nanoparticles of NaTi1.9Sn0.1(PO4)3@C (NTSP@C). The porous morphology of NTST@C is controlled through a trace amount of tin doping while selecting a fire‐new carbon source. The NTSP@C materials present a nanosized structure with a hollow morphology, exhibiting a large specific surface area of ≈71.0 m2 g−1 and a average bore diameter of ≈26.4 nm. Moreover, the carbon layer is ≈5 nm thick with a mass ratio of 6.81%. The NTSP@C sample displays an ultrastrong rate capability (128.8 mA h g−1 at 0.1 C and 101.5 mA h g−1 at 10 C at 1.5–3.0 V) and a superior cycling performance (126.3–115.8 mA h g−1 after 300 cycles at 1 C for a retention ratio of 91.7% and 101.4–87.1 mA h g−1 after 2000 cycles at 10 C for a retention ratio of 85.9%). These excellent electrochemical performances are due to the nanosized structure, unique morphology, and thin carbon layer as a conductive medium. It is clear that the NTSP@C material is a promising anode material that can be incorporated into sodium‐ion batteries to achieve superior electrochemical performance. [ABSTRACT FROM AUTHOR]

Metal sulfides show promise for use in alkali‐ion batteries because of their high theoretical capacities. However, their poor cycling stability and rate performance hinder their further development. To avoid these issues, In2S3 into Sb2S3 is introduced to improve its electrochemical properties by optimizing its crystal structure and sodium storage mechanism. A heterostructure composed of In2S3 and Sb2S3 shows a unique morphology of formicary microspheres, which provide abundant channels for fast transfer of sodium ions, large surface area for a high pseudocapacitance effect, and enough voids to relieve volume expansion. A sodium‐ion battery containing the bimetallic sulfide anode exhibits a high reversible capacity of 400 mA h g−1 and long cycle life of about 1000 cycles. Similarly, a high capacity of ≈610 mA h g−1 is achieved for a lithium‐ion battery containing the anode. During sodiation/desodiation, the synergistic effect of In2S3 and Sb2S3 enhances electronic conductivity and supports the host structure, preventing collapse. The cycling performance and rate performance of the In2S3–Sb2S3 anode are further improved by wrapping the electrode with carbon nanotubes. Even at a high current density of 3.2 A g−1, this carbon composite structure still shows a capacity of about 355 mA h g−1. A In2S3–Sb2S3 heterostructure exhibits superior performance as a sodium‐ion batteries anode. This can be attributed to special construction providing strong pseudocapacitance effect and fast sodium storage dynamics; electrochemically inert In‐containing component forming a buffer layer to relieve volume expansion; and enhanced electronic conductivity of In2S3‐Sb2S3 and a reduced energy barrier for Na+ ion migration.
