The rapid expansion of the photovoltaic industry has generated heavily oxidized waste silicon(wSi),which hinders efficient recycling owing to its small particle size and uncontrolled surface oxidation.This study introduces a molten salt electrochemical strategy for converting photovoltaic wSi into NiSi2-silicon nanorods(NiSi2-SiNRs)as high-performance anode materials for lithium-ion batteries.A stable oxidized passivation layer is formed on the wSi surface via controlled oxidation,and further in situ generated highly active NiSi2 droplets.The molten salt electric field modulates the surface energy of silicon,while particle integration drives localized directional growth,enabling the self-assembly of NiSi2-SiNRs composites.These NiSi2-SiNRs anodes exhibit rapid ion transport and effective strain buffering.The high aspect ratio of SiNRs and the presence of retained NiSi2 facilitate both longitudinal and transverse Li+ diffusion.Owing to their robust structural design,the NiSi2-SiNRs anode achieves an excellent initial Coulombic efficiency of 91.61%and retains 72.99%of its capacity after 800 cycles at 2 A·g−1.This study establishes a model system for investigating silicide/silicon interfaces in molten salt electrochemical synthesis and provides an effective strategy for upcycling photovoltaic wSi into high-performance lithium-ion battery anodes. 展开更多

Aqueous zinc‐ion batteries(AZIBs)have attracted increasing attention in energy storage owing to their high energy density,low redox potential,and cost‐effectiveness.Nevertheless,uncontrolled dendrite accumulation,gas generation,and severe side‐reaction problems hinder the cycling lifespan,which prevents their commercial applications.Herein,array‐like porous channels decorated by Na2SiO3sites were in situ created on the diatomite layers by etching with NaOH(DH).DFT calculation results demonstrate that in situ formed Na2SiO3possesses improved Zn2+affinity.The negative 3D porous channels combined with zincophilic Na2SiO3sites provide a fast Zn2+transport pathway and facilitate the ion‐pair dissociation of ZnSO4,ensuring favorable Zn2+transfer kinetics and inhibited side reactions.Moreover,the ordered array‐like structure not only can exert a spatial confinement effect to suppress the 2D diffusion of Zn2+but also drive Zn metal preferential deposit toward the rigid microaligned channels and curb the formation of large‐scale zinc dendrites.Additionally,the hydrophobic diatomite protective layer can accelerate desolvation kinetics of Zn(H2O)62+and suppress the hydrogen evolution reactions.As a result,the DH‐modified Zn anode(DH@Zn)achieves a long cycle lifespan of 2500 h at 1 mA cm−2,much more than that of bare Zn(~100 h lifespan)in symmetrical cells.Besides,the DH@Zn//NH4V4O10(NVO)full cells demonstrate a high‐capacity retention of 93.3%after 1800 cycles at 5 A g−1.This work provides a promising strategy and new insights into the design of electrolyte‐anode interfacial protection. 展开更多

Electrocatalytic carbon dioxide reduction reaction(eCO2RR)holds great promise in producing value-added chemicals,and achieving carbon neutrality.However,the efficiency of eCO2RR is often hindered by the sluggish oxygen evolution reaction(OER)at the anode.Thereby,various strategies have been developed to boost anode reaction,aiming to realize economic viability and reduce energy consumption in an eCO2RR electrolyzer.To give a comprehensive overview of anode engineering for optimizing eCO2RR,this review summarizes and discusses the cutting-edge anodic design strategies from recent research progress.They mainly include the direct substitution of OER to the value-added oxidation reaction of other small molecules,the introduction of photo/bio-assistance anodes,and the construction of metal-CO2batteries.Furthermore,the emerging challenges and a forward-looking perspective on anode development by coupling renewable energy,sewage treatment and eCO2RR are also proposed. 展开更多

This work is devoted to the development of a low cost dimensionally stable anode with high oxygen evolution catalytic activity for practical applications.For this purpose,a Ti/SnOx/MnO2 anode was fabricated through an innovative strategy involving Sn electrodeposition,oxidation,and MnO2-layer preparation.The structure of the anode was characterized,and the oxygen evolution performance was evaluated in a H2SO4 solution.The results show that compared with the Ti/SnO2/MnO2 anode prepared by the conventional brushing-annealing process,the Ti/SnOx/MnO2 anode fabricated through the innovative procedure exhibits a lower oxygen evolution potential and a nearly 40%longer accelerated lifespan.The superior oxygen evolution performance of the Ti/SnOx/MnO2 anode is attributed to the distinctive SnOx intermediate layer fabricated through Sn electrodeposition followed by oxidation,which indicates the great potential of the anode as a dimensionally stable anode for metal electrowinning and hydrogen production by electrolysis,etc. 展开更多

Halide perovskite materials have received considerable attention for solar cells,LEDs,lasers etc.owing to their controllable physicochemical properties and structural advantages.However,little research has focused on energy storage and conversion applications,such as use as anodes in lithium-ion batteries.In this paper,all-inorganic lead-free halide perovskite Cs3Bi2Cl9powders were synthesized by the grinding method,and the lattice was successfully adjusted via introducing Mn2+.The characterization results show that Mn-ion substitution can cause local lattice distortion to restructure the lattice,which will cause a mixed arrangement of[BiCl6]octahedra to improve the performance of the anode material.This new material can provide a feasible solution for solving the problem of low specific capacity anode materials caused by unstable crystal structures,and also indicates that such perovskites with unique crystal structures and lattice tunability have broad application prospects in lithium-ion batteries. 展开更多

Aqueous zinc-ion batteries(ZIBs)are promising candidates for next-generation energy storage,but the problems related to Zn dendrites and side reactions severely hinder their practical applications.Herein,a self-recognition separator based on a Bi-based metal-organic framework(GF@CAU-17)is developed for ion management to achieve highly reversible Zn anodes.The GF@CAU-17 has self-recognition behavior to customize selective Zn2+channels,effectively repelling SO42-and H2O,but facilitating Zn2+conduction.The inherent properties of CAU-17 result in the repulsion of SO42-ions while disrupting the hydrogen bond network among free H2O molecules,restraining side reactions and by-products.Simultaneously,the zincophilic characteristic of CAU-17 expedites the desolvation of[Zn(H2O)6]2+,leading to a self-expedited Zn2+ion pumping effect that dynamically produces a steady and homogeneous Zn2+ion flux,and thereby alleviates concentration polarization.Consequently,a symmetric cell based on the GF@CAU-17 separator can achieve a long lifespan of 4450 h.Moreover,the constructed Zn//GF@CAU-17//MnO2cell delivers a high specific capacity of 221.8 mAh g-1and 88.0%capacity retention after 2000 cycles. 展开更多

Aqueous zinc-ion batteries (AZIBs) are fundamentally challenged by the instability of the electrode/electrolyte interface,predominantly due to irreversible zinc (Zn) deposition and hydrogen evolution.Particularly,the intricate mechanisms behind the electrochemical discrepancies induced by interfacial Zn2+-solvation and deposition behavior demand comprehensive investigation.Organic molecules endowed with special functional groups (such as hydroxyl,carboxyl,etc.) have the potential to significantly optimize the solvation structure of Zn2+and regulate the interfacial electric double layer (EDL).By increasing nucleation overpotential and decreasing interfacial free energy,these functional groups facilitate a lower critical nucleation radius,thereby forming an asymptotic nucleation model to promote uniform Zn deposition.Herein,this study presents a pioneering approach by introducing trace amounts of n-butanol as solvation regulators to engineer the homogenized Zn (H-Zn) anode with a uniform and dense structure.The interfacial reaction and structure evolution are explored by in/ex-situ experimental techniques,indicating that the H-Zn anode exhibits dendrite-free growth,no by-products,and weak hydrogen evolution,in sharp contrast to the bare Zn.Consequently,the H-Zn anode achieves a remarkable Zn utilization rate of approximately 20% and simultaneously sustains a prolonged cycle life exceeding 500 h.Moreover,the H-Zn//NH4V4O10(NVO) full battery showcases exceptional cycle stability,retaining 95.04%capacity retention after 400 cycles at a large current density of 5 A g-1.This study enlightens solvation-regulated additives to develop Zn anode with superior utilization efficiency and extended operational lifespan. 展开更多

Constructing unique and highly stable structures with plenty of electroactive sites in sodium storage materials is a key factor for achieving improved electrochemical properties through favorable sodium ion di usion kinetics. An SnS_2@carbon hollow nanospheres(SnS_2@C) has been designed and fabricated via a facile solvothermal route, followed by an annealing treatment. The SnS_2@C hybrid possesses an ideal hollow structure, rich active sites, a large electrode/electrolyte interface, a shortened ion transport pathway, and, importantly, a bu er space for volume change, generated from the repeated insertion/extraction of sodium ions. These merits lead to the significant reinforcement of structural integrity during electrochemical reactions and the improvement in sodium storage properties, with a high specific reversible capacity of 626.8 mAh g-1 after 200 cycles at a current density of 0.2 A g-1 and superior high-rate performance(304.4 mAh g-1 at 5 A g-1). 展开更多

Self-organized titanium dioxide(TiO2)nanotubes,which are prepared by electrochemical anodizing,have been widely researched as promising anodes for Liion batteries.Both nanotubular morphology and bulk structure of TiO2nanotubes can be easily changed by adjusting the anodizing and annealing parameters.This is provided to investigate different phenomena by selectively adjusting a specific parameter of the Li+insertion mechanism.In this paper,we reviewed how the morphology and crystallography of TiO2nano tubes influence the electrochemical performance of Li+batteries.In particular,electrochemical performances of amorphous and anatase titanium dioxide nanotube anodes were compared in detail.As we all know,TiO2nanotube anodes have the advantages of nontoxicity,good stability,high safety and large specific surface area,in lithium-ion batteries.However,they suffer from poor electronic conductivity,inferior ion diffusivity and low theoretical capacity(335 mAh·g-1),which limit their practical application.Generally,there are two ways to overcome the shortcomings of titanium dioxide nanotube anodes,including doping and synthesis composites.The achievements and existing problems associated with doped TiO2nanotube anodes and composite material anodes are summarized in the present review.Based on the analysis of lithium insertion mechanism of titanium dioxide nanotube electrodes,the prospects and possible research directions of TiO2anodes in lithiumion batteries are discussed. 展开更多

A novel SnO2-based gas anode was developed for aluminum electrolysis in molten cryolite at 850 ＆#176;C to reduce energy consumption and decrease CO2 emissions. Hydrogen was introduced into the anode, participating in the anode reaction. Carbon and aluminum were used as the cathode and reference electrodes, respectively. Cyclic voltammetry was applied in the cell to investigate the electrochemical behavior of oxygen ion on platinum and SnO2-based materials. The potential for oxygen evolution on these electrode materials was determined. Then, galvanostatic electrolysis was performed on the gas anode, showing a significant depolarization effect （a decrease of ~0.8 V of the anode potential） after the introduction of hydrogen, compared with no gas introduction or the introduction of argon. The results indicate the involvement of hydrogen in the anode reaction （three-phase-boundary reaction including gas, electrolyte and electrode） and give the possibility for the utilization of reducing gas anodes for aluminum electrolysis. 展开更多

Aqueous zinc-ion battery(ZIB)featuring with high safety,low cost,environmentally friendly,and high energy density is one of the most promising systems for large-scale energy storage application.Despite extensive research progress made in developing high-performance cathodes,the Zn anode issues,such as Zn dendrites,corrosion,and hydrogen evolution,have been observed to shorten ZIB’s lifespan seriously,thus restricting their practical application.Engineering advanced Zn anodes based on two-dimensional(2D)materials are widely investigated to address these issues.With atomic thickness,2D materials possess ultrahigh specific surface area,much exposed active sites,superior mechanical strength and flexibility,and unique electrical properties,which confirm to be a promising alternative anode material for ZIBs.This review aims to boost rational design strategies of 2D materials for practical application of ZIB by combining the fundamental principle and research progress.Firstly,the fundamental principles of 2D materials against the drawbacks of Zn anode are introduced.Then,the designed strategies of several typical 2D materials for stable Zn anodes are comprehensively summarized.Finally,perspectives on the future development of advanced Zn anodes by taking advantage of these unique properties of 2D materials are proposed. 展开更多

Sodium ion batteries and capacitors have demonstrated their potential applications for next-generation low-cost energy storage devices.These devices’s rate ability is determined by the fast sodium ion storage behavior in electrode materials.Herein,a defective TiO2@reduced graphene oxide(M-TiO2@rGO)self-supporting foam electrode is constructed via a facile MXene decomposition and graphene oxide self-assembling process.The employment of the MXene parent phase exhibits distinctive advantages,enabling defect engineering,nanoengineering,and fluorine-doped metal oxides.As a result,the M-TiO2@rGO electrode shows a pseudocapacitance-dominated hybrid sodium storage mechanism.The pseudocapacitance-dominated process leads to high capacity,remarkable rate ability,and superior cycling performance.Significantly,an M-TiO2@rGO//Na3 V2(PO4)3 sodium full cell and an M-TiO2@rGO//HPAC sodium ion capacitor are fabricated to demonstrate the promising application of M-TiO2@rGO.The sodium ion battery presents a capacity of 177.1 mAh g-1 at 500 mA g-1 and capacity retention of 74%after 200 cycles.The sodium ion capacitor delivers a maximum energy density of 101.2 Wh kg-1 and a maximum power density of 10,103.7 W kg-1.At 1.0 A g-1,it displays an energy retention of 84.7%after 10,000 cycles. 展开更多

Lithium metal batteries(LMBs) with a high theoretical capacity are seen as a type of the most potential energy storage system.Unfortunately,the growth of lithium dendrite,the irreversible side reactions,and the infinite volume alteration still curb the practical utilization of lithium metal anodes,resulting in low Coulombic efficiency(CE) and safety problems,etc.Herein,we synthesize a lithiophilic 3D copper foam host with uniformly distributed nano-flower-like ZnO particles(CuF/ZnO) and obtain the composite lithium metal anode containing the Li2O,LiZn alloy,and pure Li by the infusion of molten Li(CuF/Li2O-LiZn@Li).Benefitting from the advantages of the 3D structure of copper foam and the lithiophilicity of ZnO sites,the composite lithium metal anode can restrain the volume alternation and regulate the uniform deposition of lithium.The symmetrical cells of the composite lithium metal anode have a 1600 h long cycle life with a low polarization voltage of 15 mV,and the Coulombic efficiency can maintain about 97.8% at 1.0 mA·cm-2,1.0mAh·cm-2. 展开更多

NiFe2O4-10NiO-based cermet inert anodes for aluminium electrolysis were prepared and their properties were investigated in a lab-scale electrolysis cell. The results show that the inert anodes exhibit good performance during electrolysis in molten salt cryolite at 960 °C, but according to the analyses of phase compositions and microstructures through XRD, SEM/EDX and metallographic analysis, the metal in the anodes is preferentially corroded and many pores are produced on the anode surface after electrolysis. The preferential dissolution of Fe in the NiFe2O4 phase may lead to the non-uniform corrosion of NiFe2O4 grains. Moreover, a dense protective layer of NiFe2O4-NiAl2O4-FeAl2O4 is formed on the anode surface, which originates from the reaction of Al2O3 dissolved in the electrolyte with NiO or FeO, the annexation of NiFe2O4-NiAl2O4-FeAl2O4 to NiO and volume expansion. Thus, the dense NiFe2O4-NiAl2O4-FeAl2O4 layer inhibits the metal loss and ceramic-phase corrosion on the surface of the cermet inert anodes. 展开更多

Tin dioxide(SnO2)with a high theoretical specific capacity of 1494 mAh g-1is a promising candidate anode material for lithium storage.However,the shortcomings of serious volume expansion and low conductivity limit its wide application.Herein,coaxial nano-multilayered C/SnO2/TiO2composites were fabricated via layerby-layer self-assembly of TiO2and SnO2-gel layers on the natural cellulose filter paper,followed by thermal treatment under a nitrogen atmosphere.Through engineering design of the assembly process,the optimal C/SinO2/TiO2composite features five alternating SnO2and TiO2nanolayers,with TiO2as the outside shell(denoted as C/TSTST).This unique structure endows the C/TSTST with excellent structural stability and electrochemical kinetics,making it a high-performance anode for lithium-ion batteries(LIBs).The C/TSTST composite delivers a high reversible capacity of 676 mAh g-1at 0.1 A g-1after 200 cycles and retains a capacity of 504 mAh g-1at 1.0 A g-1,which can be recovered to 781 mAh g-1at 0.1 A g-1The significantly enhanced electrochemical performance is attributed to the hierarchical hybrid structure,where the carbon core combined with coaxial TiO2nanolayers serves as a structural scaffold,ameliorating volume change of SnO2while creating abundant interfacial defects for enhanced lithium storage and rapid charge transport.These findings are further demonstrated by the density functional theory(DFT)calculations.This work provides an efficient strategy for designing coaxial nano-multilayered transition metal oxide-related electrode materials,offering new insights into high-performance LIBs anodes. 展开更多

Aqueous zinc ion batteries(AZIBs)are an advanced secondary battery technology to supplement lithiumion batteries.It has been widely concerned and developed recently based on the element abundance and safety advantages.However,AZIBs still suffer from serious problems such as dendrites Zn,hydrogen evolution corrosion,and surface passivation,which hinder the further commercial application of AZIBs.Herein,an in-situ ZnCr2O4(ZCO)interface endows AZIBs with dendrite-free and ultra-low polarization by realizing Zn2+pre-desolvation,constraining H2O-induced corrosio n,and boosting Zn2+transport/deposition kinetics.The ZCO@Zn anode harvests an ultrahigh cumulative capacity of~20000 mA h cm-2(cycle time:over 4000 h)at a high current density of 10 mA cm-2,indicating excellent reversibility of Zn deposition,Such superior performance is among the best cyclability in AZIBs.Moreover,the multifunctional ZCO interface improves the Coulombic efficiency(CE)to 99.7%for more than 2600 cycles.The outstanding electrochemical performance is also verified by the long-term cycle stability of ZCO@Zn//α-MnO2 full cells.Notably,the as-proposed method is efficient and low-cost enough to enable mass production.This work provides new insights into the uniform Zn electrodeposition at the scale of interfacial Zn2+predesolvation and kinetics improvement. 展开更多

Transition metal selenides are considered promising electrochemical energy storage materials due to their excellent rate properties and high capacity based on multi-step conversion reactions.However,its practical applications are hampered by poor conductivity and large volume variation for Na+storage,which resulting fast capacity decay.Herein,a facile metal-organic framework(MOF)derived method is explored to embed Cu2-xSe@C particles into a carbon nanobelts matrix.Such carbon encapsulated nanobelts'structural moderate integral electronic conductivity and maintained the structure from collapsing during Na+insertion/extraction.Furthermore,the porous structure of these nanobelts endows enough void space to mitigate volume stress and provide more diffusion channels for Na+/electrons transporting.Due to the unique structure,these Cu2-xSe@C nanobelts achieved ultra-stable cycling performance(170.7 m Ah/g at1.0 A/g after 1000 cycles)and superior rate capability(94.6 m Ah/g at 8 A/g)for sodium-ion batteries.The kinetic analysis reveals that these Cu2-xSe@C nanobelts with considerable pesoudecapactive contribution benefit the rapid sodiation/desodiation.This rational design strategy broadens an avenue for the development of metal selenide materials for energy storage devices. 展开更多

Electrochemically active metal anodes,such as lithium,sodium,potassium,and zinc,have attracted great research interests in the advanced rechargeable batteries owing to their superior theoretical energy densities.Unfortunately,the metal anodes suffer from the huge volume changes with loss of active materials during the plating and stripping processes,resulting in fast capacity decay.Moreover,the random growth of dendrites on the metal anodes will penetrate the separator,causing severe safety issues.Engineering metal anodes by introducing the 2D materials are widely investigated to alleviate these issues.Benefitting from the ultrathin structure feature and unique electrical properties,2D materials are regarded as one of the best host of metal anodes.Besides,the tunable active sites on basal plane enable 2D materials to achieve favorable interaction with metal anodes.Moreover,some 2D materials exhibit good mechanical strength and flexibility,serving as building block for the artificial solid electrolyte interphase.In this review,we mainly disclosed the correlations between the intrinsic properties of 2D materials and their functions in guiding uniform nucleation,controlling the growth of metals,and accommodating the volume change.Also,the challenges of 2D materials in metal anodes are well discussed.Finally,the future directions to develop highperformance metal anodes by taking advantage of these unique features of 2D materials are proposed. 展开更多
