文摘Rechargeable magnesium batteries(RMBs)are a cutting-edge energy storage solution,with several advantages over the state-of-art lithiumion batteries(LIBs).The use of magnesium(Mg)metal as an anode material provides a much higher gravimetric capacity compared to graphite,which is currently used as the anode material in LIBs.Despite the significant advances in electrolyte,the development of cathode material is limited to materials that operate at low average discharge voltage(<1.0 V vs.Mg/Mg^(2+)),and developing high voltage cathodes remains challenging.Only a few materials have been shown to intercalate Mg^(2+)ions reversibly at high voltage.This review focuses on the structural aspects of cathode material that can operate at high voltage,including the Mg^(2+)intercalation mechanism in relation to its electrochemical properties.The materials are categorized into transition metal oxides and polyanions and subcategorized by the intrinsic Mg^(2+)diffusion path.This review also provides insights into the future development of each material,aiming to stimulate and guide researchers working in this field towards further advancements in high voltage cathodes.

文摘With the rapid development of industry,the environmental problems caused by heavy metal arsenic and antimony are becoming increasingly serious.Therefore,it is urgent to solve the problem of arsenic and antimony pollution in the water environment.Renewable carbon-based materials,as a kind of adsorbent widely used in wastewater treatment,have been the focus of scholars’research for many years.In this review,the preparation methods,characteristics,and applications of renewable carbon-based materials(biochar,activated carbon,carbon nanotubes,and graphene)for the removal of arsenic and antimony are described in detail.Based on adsorption kinetics,isothermal adsorption,temperature,pH,and coexisting ions,we discuss the process of adsorption of arsenic and antimony by renewable carbon-based materials,explore the mechanism of adsorption of anions in water by renewable carbon-basedmaterials,and comparatively analyze the differences in adsorption performance of arsenic and antimony by different renewable carbon-based materials.Compared with biochar,activated carbon,carbon nanotube,and graphene renewable materials loaded with iron-manganese oxides have better removal effects on arsenic and antimony wastewater.Extensive research data shows that biochar,as a renewable material,is recommended,followed by activated carbon.Both are recommended because of their excellent adsorption properties and low production costs.Finally,the prospects and challenges of the application of renewable carbon-based materials in wastewater treatment are discussed,and the directions and development trends of future research are pointed out,which provide references and insights for further promoting the application of renewable carbon-based materials in wastewater treatment.

文摘Magnesium-ion batteries hold promise as future energy storage solutions,yet current Mg cathodes are challenged by low voltage and specific capacity.Herein,we present an AI-driven workflow for discovering high-performance Mg cathode materials.Utilizing the common characteristics of various ionic intercalation-type electrodes,we design and train a Crystal Graph Convolutional Neural Network model that can accurately predict electrode voltages for various ions with mean absolute errors(MAE)between0.25 and 0.33 V.By deploying the trained model to stable Mg compounds from Materials Project and GNoME AI dataset,we identify 160 high voltage structures out of 15,308 candidates with voltages above3.0 V and volumetric capacity over 800 mA h/cm^(3).We further train a precise NequIP model to facilitate accurate and rapid simulations of Mg ionic conductivity.From the 160 high voltage structures,the machine learning molecular dynamics simulations have selected 23 cathode materials with both high energy density and high ionic conductivity.This Al-driven workflow dramatically boosts the efficiency and precision of material discovery for multivalent ion batteries,paving the way for advanced Mg battery development.

文摘Carbon-based materials have been widely applied for pollutant removal relying on their rich pore structure,functional groups,chemical stability,and expandability.However,the traditional manufacturing process of carbon materials based on organic compounds pyrolysis is high energy-consuming and high-emission,which is not conducive to addressing the climate crisis and achieving the goal of carbon neutrality.Molten salt electrolysis technology enables the direct capture and reduction of CO_(2)to produce solid carbon,resulting in significant environmental benefits while achieving carbon emissions reduction.The molten salt also has a purification function,enabling the production of high-purity carbon materials.The kinetics of the electrochemical reduction process can be easily controlled,and the co-reduction of multiple elements provides convenience for the in-situ optimization of carbon material structure and the expansion of its applications.Therefore,this review focuses on the thermodynamics&kinetics processes of molten salt capture and electrochemical reduction of CO_(2)to prepare carbon materials.It further reviews the recent research progress on the preparation of carbon materials for pollutant removal based on molten salt electrochemical processes for the first time.Finally,we analyze the advantages and challenges of the current molten salt electrochemical processes and offers prospects for future research directions.

文摘P3-type manganese-iron-based cathodes with high specific capacity and abundant resource have attracted considerable attention for sodium-ion batteries.However,the long-term cycle stability of P3-type cathodes is still not satisfactory.In this work,we design a new quaternary manganese-iron-based cathode material(P3-Na_(0.54)Mn_(0.64)Fe_(_(0.1)6)Mg_(0.1)Cu_(0.1)O_(2))by Cu substitution.The strong covalent Cu-O bonds improve the structural stability and the reversibility of O redox during charge and discharge processes.Cu substitution also mitigates the structure change with less unit cell volume variation,and improves the Na-ion transport kinetics effectively.As a result,NMFMC delivers much improved cycling stability and rate capability compared with NMFM.It reveals that the charge compensation of NMFMC is mainly contributed by Mn^(3+/4+),Fe^(3+/3.5+)and O_(2-/-)during the charge and discharge processes,and Cu substitution can also enhance the activity and reversibility of Fe redox.This strategy provides a new pathway toward improving the stability and O redox reversibility of P3-type cathode materials for sodium-ion batteries.

文摘Sluggish conversion reaction kinetics and spontaneous shuttle effect of lithium polysulfides(LiPSs)are deemed as the two big mountains that hinder the practical application of lithium-sulfur batteries(LSBs).Herein,dual-defect engineering strategy is implemented by introducing boron-doping and phosphorusvacancy sites with MoP@NC composite as the precursor.Based on the experimental characterizations and theoretical calculations,B-MoP_(1-x)@NC-based electrode presents low oxidation potential,high lithium diffusivity,small Tafel slope and strong adsorption capability for polysulfides,which is beneficial to enhance the adsorption capability for LiPSs,reduce the lithium diffusion energy barriers and Gibbs free energy for the conversion reactions of LiPSs.As demonstrated,the corresponding Li-S/B-MoP1-x@NC batteries can remain high reversible capacity of 753 mAh/g at 0.5 C after 300 cycles,and keep a stable capacity of 520 mAh/g at 0.5 C after 100 cycles even at the high-loading content of 5.1mg/cm^(2).According to the results of in-situ UV–vis spectra,the satisfactory battery performance majorly originates from the existence of dual-defect characteristics in B-MoP1-x@NC catalyst,which effectively promotes the conversion reaction kinetics of LiPSs,and restrains the shuttle behavior of LiPSs.The key ideas of this work will enlighten the development of catalytic cathode materials for sulfur-based secondary batteries.

文摘With the rapid development of new energy and the high proportion of new energy connected to the grid,energy storage has become the leading technology driving significant adjustments in the global energy landscape.Electrochemical energy storage,as the most popular and promising energy storage method,has received extensive attention.Currently,the most widely used energy storage method is metal-ion secondary batteries,whose performance mainly depends on the cathode material.Prussian blue analogues(PBAs)have a unique open framework structures that allow quick and reversible insertion/extraction of metal ions such as Na^(+),K^(+),Zn^(2+),Li^(+)etc.,thus attracting widespread attention.The advantages of simple synthesis process,abundant resources,and low cost also distinguish it from its counterparts.Unfortunately,the crystal water and structural defects in the PBAs lattice that is generated during the synthesis process,as well as the low Na content,significantly affect their electrochemical performance.This paper focuses on PBAs’synthesis methods,crystal structure,modification strategies,and their potential applications as cathode materials for various metal ion secondary batteries and looks forward to their future development direction.
