To control the power hierarchy design of lithium-ion battery(LIB)builtup sets for electric vehicles(EVs),we offer intensive theoretical and experimental sets of choice anode/cathode architectonics that can be modulated in full-scale LIB built-up models.As primary structural tectonics,heterogeneous composite superstructures of full-cell-LIB(anode//cathode)electrodes were designed in closely packed flower agave rosettes TiO2@C(FRTO@C anode)and vertical-star-tower LiFePO4@C(VST@C cathode)building blocks to regulate the electron/ion movement in the three-dimensional axes and orientation pathways.The superpower hierarchy surfaces and multi-directional orientation components may create isosurface potential electrodes with mobile electron movements,in-to-out interplay electron dominances,and electron/charge cloud distributions.This study is the first to evaluate the hotkeys of choice anode/cathode architectonics to assemble different LIB-electrode platforms with high-mobility electron/ion flows and high-performance capacity functionalities.Density functional theory calculation revealed that the FRTO@C anode and VST-(i)@C cathode architectonics are a superior choice for the configuration of full-scale LIB built-up models.The integrated FRTO@C//VST-(i)@C full-scale LIB retains a huge discharge capacity(~94.2%),an average Coulombic efficiency of 99.85%after 2000 cycles at 1 C,and a high energy density of 127 Wh kg?1,thereby satisfying scale-up commercial EV requirements. 展开更多

This review summarizes the cutting-edge applications of artificial intelligence(AI)technology in the development and performance optimization of key materials for sodium-ion batteries(SIBs),with a primary focus on its breakthrough advancements in the innovation of cathode and anode materials.It highlights the pivotal role of AI in accelerating the discovery and optimization process of highperformance SIB materials.In the research and development of cathode materials,AI technology,through machine learning and deep learning algorithms,assists in the design of layered oxides and poly-anion compounds,optimizes the ratio of transition metals and crystal structure,and enhances the kinetics of Na+intercalation/deintercalation and structural stability.In terms of anode materials,AI technology leverages data-driven high-throughput screening strategies and microstructural modulation models to drive breakthroughs in key performance metrics such as sodium storage capacity and rate capability for hard carbon,alloy-based,and conversion-type anode materials.AI technology successfully establishes a new development paradigm of“data-driven,mechanism-embedded”,achieving full-chain coverage from atomic-scale material design to system-level performance optimization,significantly reducing development cycle and costs.Based on a summary of the current application status of AI technology in the development of SIBs materials,this review further analyzes the challenges that this field is facing,and at the same time looks forward to the development opportunities of the in-depth integration of AI and experimental research and development,providing innovative methodological support and direction guidance for promoting the industrialization process of high-performance SIBs. 展开更多

Vacuum carbon thermal reduction has been widely studied for the recovery of ternary lithium batteries,and there are many choices for the type of carbon to be reduced in this method,such as expensive carbon nanotubes and inexpensive battery anode carbon.In this paper,the vacuum reduction of ternary lithium batteries cathode materials by carbon nanotubes was investigated,and it was confirmed that carbon nanotubes,as a high-quality carbon with high carbon content and large specific surface area,can achieve very excellent reduction results.Using concentrated sulfuric acid with a concentration of 98%and H₂O₂with a concentration of 60%,swollen anode carbon as the reduced carbon,the direct yields of Li and Mn were above 99%at a vacuum of 10 Pa,a temperature of 1623 K,a pressurized material pressure of 0 MPa,and a roasting time of 90 min,similar to the effect of expensive carbon nanotubes,and the roasting time was lower than that of the unetched anode carbon.This process improves the reduction efficiency and saves energy consumption in vacuum carbothermal reduction of waste ternary lithium batteries cathode materials. 展开更多

Lithium-ion batteries(LIBs)exhibit significant performance deterioration in low-temperature environments.Key challenges include severely hindered lithium-ion transport kinetics,substantial capacity loss,and inadequate charging capability,which collectively limit their application in electric vehicles,aerospace,and deep-sea exploration.This study demonstrates the development of a Sn/P/LiNi0.8Mn0.1Co0.1O2composite anode via ball milling of Sn,P and LiNi0.8Mn0.1Co0.1O2(abbreviated as T8),which achieves exceptional high-rate capability and stable cycling performance for lithium storage under low-temperature conditions.The composite anode delivers a reversible capacity of 660 mAh g-1after 150cycles at 0.5 A g-1under-10°C and maintains 680 mAh g-1after 50 cycles at-30℃,even with conventional electrolytes.The incorporation of T8 cathode material facilitates in-situ formation of amorphous Sn-O-P oxides and Li3P,enhancing ionic conductivity,prelithiation,and reaction kinetics.Transition metals from T8 act as catalytic sites,reducing charge-transfer resistance and enabling high-rate performance(e.g.,480 mAh g-1at 15 A g-1in full cells).This work provides a sustainable strategy for designing advanced anode materials with superior low-temperature resilience and high capacity for next-generation LIBs. 展开更多

Sodium-ion capacitors(SICs)typically feature a hybrid design,incorporating a battery-type anode that operates by faradaic redox reactions and an activated carbon cathode that functions through electrical double-layer(EDL)adsorption/desorption.However,the kinetics of faradaic processes are inherently slower than those of EDL processes,leading to a fundamental problem known as kinetic imbalance between the electrodes,which hinders the development of high-performance SICs.To address this,we synthesized composites of bismuth nanoparticles in N-doped carbon(Bi@NC)by a high-temperature sintering method.The resulting Bi@NC anode has a specific capacity of 300 mAh g-1 at 0.5 A g-1,an exceptional rate capability(maintaining performance at currents exceeding 75 A g-1),and outstanding cycling sta-bility over 12000 cycles.Three-electrode Swagelok cell tests revealed that this high-rate Bi@NC composite effectively decreases the kinetic gap with the activated carbon cathode,as shown by an analysis of their respective potential swing windows(vs.Na/Na+).This enables the fabricated SIC to achieve a maximum energy density of 115 Wh kg-1,a peak power density of 45535 W kg-1,and a long cycle life exceeding 8000 cycles. 展开更多

The advancement of aqueous zinc metal batteries(ZMBs)is constrained by intrinsic interfacial issues in aqueous electrolyte systems.Here,using numerical simulation,we decipher the multi-scale causes of interfacial instability,elucidating the synergistic effect of macroscopic ineffective regions and microscopic passivation.Based on the analysis,we develop an electrolyte-triggered interphase construction strategy to resolve the interfacial failure.This strategy couples the in situ formation of hydrogel interphase on both the anode and cathode with the electrolyte filling process,thereby(1)facilitating contact between electrodes and the separator;(2)promoting anode reversibility through inducing a bilayer SEI that enhances Zn2+desolvation kinetics and blocks electron tunneling;(3)ensuring long-term cathode cycling stability via restricting the irreversible dissolution of MnO2and side-reactions.The resultant Zn metal anode exhibited a near-unity Coulombic efficiency(99.5%)for Zn plating/stripping at an extremely low current density of 0.1 mA cm-2and the Zn/MnO2full cell sustained 2000 full-duty-cycles with an exceptionally low decay rate of 0.0051%per-cycle.This work unlocks an alternative angle for promoting practical ZMB s toward more sustainable energy storage systems. 展开更多

High-voltage Li-rich Mn-based oxide(LRMO)cathodes are promising for breaking through the energy density limits of lithium-ion batteries,yet their practical application remains limited by electrochemical performance degradation caused by unstable cathode-electrolyte interphase(CEI)evolution during longterm cycling.To address this issue,we propose a novel surface modification strategy using La0.7Sr0.3MnO3-σ(LSMO)nanodots,which exhibit high electronic co nductivity and excellent corrosion resistance.These nanodots act as stable anchoring sites,facilitating the formation of a robust CEI on LRMO,The LSMOmodified cathode demonstrates significantly improved anionic redox reversibility,effectively mitigating transition metal migration and lattice oxygen loss.Furthermore,the optimized interfacial electrochemical kinetics ensure sustained rapid Li+diffusion throughout cycling,while the formation of a stable trilayer CEI structure suppresses electrolyte decomposition.Benefiting from these synergistic effects,the LSMO nanodot-engineered LRMO cathode delivers outstanding cycling stability,retaining 97.4%capacity after 300 cycles at 1 C.This work not only highlights the critical role of nanodot heterostructures in stabilizing CEI but also provides a new approach to designing high-voltage cathodes with superior interfacial compatibility and long-term durability. 展开更多

Aluminum(Al)exhibits excellent electrical conductivity,mechanical ductility,and good chemical compatibility with high-ionic-conductivity electrolytes.This makes it more suitable as an anode material for all-solid-state lithium batteries(ASSLBs)compared to the overly reactive metallic lithium anode and the mechanically weak silicon anode.This study finds that the pre-lithiated Al anode demonstrates outstanding interfacial stability with the Li_6PS_5Cl(LPSCl)electrolyte,maintaining stable cycling for over 1200 h under conditions of deep charge-discharge.This paper combines the pre-lithiated Al anode with a high-nickel cathode,LiNi0.8Co0.1Mn0.1O2,paired with the highly ionic conductive LPSCl electrolyte,to design an ASSLB with high energy density and stability.Using anode pre-lithiation techniques,along with dual-reinforcement technology between the electrolyte and the cathode active material,the ASSLB achieves stable cycling for 1000 cycles at a 0.2C rate,with a capacity retention rate of up to 82.2%.At a critical negative-to-positive ratio of 1.1,the battery's specific energy reaches up to 375 Wh kg-1,and it maintains over 85.9%of its capacity after 100 charge-discharge cycles.This work provides a new approach and an excellent solution for developing low-cost,high-stability all-solid-state batteries. 展开更多

Aqueous zinc-iodine(Zn-I2)batteries show great potential as energy storage candidates due to their high-safety and low-cost,but confronts hydrogen evolution reaction(HER)and dendrite growth at anode side and polyiodide shuttling at cathode side.Herein,"tennis racket"(TR)hydrogel electrolytes were prepared by the co-polymerization and co-blending of polyacrylamide(PAM),sodium lignosulfonate(SL),and sodium alginate(SA)to synchronously regulate cathode and anode of Zn-I2batteries."Gridline structure"of TR can induce the uniform transportation of Zn2+ions through the coordination effect to hinder HER and dendrite growth at anode side,as well as hit I3-ions as"tennis"via the strong repulsion force to avoid shuttle effect at cathode side.The synergistic effect of TR electrolyte endows Zn-Zn symmetric battery with high cycling stability over 4500 h and Zn-I2cell with the stably cycling life of 15000 cycles at5 A g-1,outperforming the reported works.The practicability of TR electrolyte is verified by flexible Zn-I2pouch battery.This work opens a route to synchronously regulate cathode and anode to enhance the electrochemical performance of Zn-I2batteries. 展开更多

Aqueous zinc-ion batteries(AZIBs)are gaining attention owing to their affordability,high safety,and high energy density,making them a promising solution for large-scale energy storage.However,their performance is hampered by the instability of both the anode-electrolyte interface and the cathode-electrolyte interface.The use of sodium gluconate(SG),an organic sodium salt with multiple hydroxyl groups,as an electrolyte additive is suggested.Experimental and theoretical analyses demonstrate that Na+from SG can intercalate and deintercalate within the associated V2O5 cathode during in situ electrochemical processes.This action supports the layered structure of V2O5,prevents structural collapse and phase transitions,and enhances Zn2+diffusion kinetics.Additionally,the gluconate anion disrupts the original Zn2+solvation structure,mitigates water-induced side reactions,and suppresses Zn dendrite growth.The synchronous regulation of both the V2O5 cathode and Zn anode by the SG additive leads to considerable performance improvements.Zn‖Zn symmetric batteries demonstrate a cycle life exceeding 2800 h at 0.5 mA cm-2and 1 mAh cm-2.In Zn‖V2O5 full batteries,a high specific capacity of 288.92 mAh g-1and capacity retention of 82.29%are maintained over 1000 cycles at a current density of 2 A g-1.This multifunctional additive strategy offers a new pathway for the practical application of AZIBs. 展开更多

Flat-panel X-ray sources(FPXSs)have many advantages in terms of compactness and low-dose imaging,enhancing their capability for novel X-ray applications.Experimental analysis of the X-ray characteristics and optimizing the anode panel of an FPXS are time-consuming,expensive,and sometimes impractical.In this study,a FPXS was prepared using a ZnO nanowire cold cathode and a molybdenum film anode target.Monte Carlo(MC)simulations were utilized to optimize the anode panel and obtain the average fluence,average energy,and spatial distribution of the X-rays for the ZnO nanowire FPXS.The accuracy of the MC simulations was verified by comparing the measured and simulated energy spectra.Optimization of the anode target considers the material,thickness,and morphology,whereas optimization of the substrate focuses on the material and thickness.The results show that the difference between the positions of the K-shell peaks in the measured and simulated energy spectra is within 0.26 keV.At the acceleration voltages of 30 kV,60 kV,and 90 kV,the optimal thicknesses of the tungsten array anode were 0.65μm,2.45μm,and 5μm,respectively,while the molybdenum array anode has the optimal thicknesses of 1.45μm,5.25μm,and 24μm,respectively.The microsemi-ellipsoidal anode with a recessed design showed a 5%increase in the transmitted X-ray fluence compared with the film target.The sapphire substrate with a thickness of 0.78 mm exhibits a mechanical strength comparable to that of a glass substrate with a thickness of 3 mm,implying that the former can increase the average X-ray fluence by reducing the filtration of X-rays.The findings of this study provide valuable guidance for the fabrication and optimization of the ZnO nanowire FPXS. 展开更多

Long-life energy storage batteries are integral to energy storage systems and electric vehicles,with lithium-ion batteries(LIBs)currently being the preferred option for extended usage-life energy storage.To further extend the life span of LIBs,it is essential to intensify investments in battery design,manufacturing processes,and the advancement of ancillary materials.The pursuit of long durability introduces new challenges for battery energy density.The advent of electrode material offers effective support in enhancing the battery’s long-duration performance.Often underestimated as part of the cathode composition,the binder plays a pivotal role in the longevity and electrochemical performance of the electrode.Maintaining the mechanical integrity of the electrode through judicious binder design is a fundamental requirement for achieving consistent long-life cycles and high energy density.This paper primarily concentrates on the commonly employed cathode systems in lithium-ion batteries,elucidates the significance of binders for both,discusses the application status,strengths,and weaknesses of novel binders,and ultimately puts forth corresponding optimization strategies.It underscores the critical function of binders in enhancing battery performance and advancing the sustainable development of lithium-ion batteries,aiming to offer fresh insights and perspectives for the design of high-performance LIBs. 展开更多

Nickel-rich layered oxides are considered highly promising cathode materials for all-solid-state batteries(ASSBs)due to their high theoretical specific capacity and energy density.In this study,a comparison between polycrystalline and single-crystalline cathode materials was conducted.It was found that,during the charging process,ion transport at the interface of polycrystalline cathodes is significantly influenced by phase transitions and side reactions with the electrolyte,resulting in an irreversible increase in impedance after cycling.Furthermore,the structural stability of the cathode material affects internal ion diffusion kinetics,thereby influencing its electrochemical performance.Unlike single-crystalline materials,ion migration in polycrystalline materials must traverse anisotropic grain boundaries,which,due to anisotropic lattice contraction,evolve into intergranular cracks,leading to reduced ion diffusion kinetics and degraded electrochemical performance.In contrast,single-crystalline cathodes exhibit more stable interfacial resistance and uniform ion transport during charging,ensuring structural stability over longterm cycling.Consequently,at a 0.5 C rate,the single-crystalline cathode maintains a specific capacity of143 m Ah/g after 500 cycles,with a capacity retention of 89.2%,while preserving its intact single-crystal morphology.This study provides valuable new insights into the localized lithium-ion transport behavior in single-crystalline and polycrystalline cathode materials for sulfide-based all-solid-state batteries. 展开更多

Hydrogel electrolytes are widely used in zinc-ion batteries(ZIBs)due to their advantages of regulating zinc deposition/stripping process,and limiting dendrite growth.However,their relatively poor ionic conductivity and mechanical properties remain significant obstacles to their practical application in ZIBs.Herein,the multi-component cross-linked polyacrylamide/carboxymethyl cellulose/agarose(PCA)hydrogel polymerized electrolytes are designed via a heat-initiated polymerization approach.The PCA hydrogel electrolytes exhibit high ionic conductivity of 38.78 mS/cm and excellent mechanical strength from 2.9 MPa to 5.6 MPa.Meanwhile,the ample hydroxyl(-OH)functional groups on the PCA hydrogel electrolytes chain can capture and anchor H2O molecules via hydrogen bonding,thus fundamentally regulating the coordination environment of Zn2+and inhibiting side reactions.The combined effect of carboxyl(-COOH)groups and amino(-NH2)groups in PCA hydrogel electrolytes can induce the uniform deposition of zinc ions.Consequently,The Zn//Zn symmetrical cell assembled with this hydrogel electrolytes demonstrate excellent cycling stability over 2500 h at the current density of 1 mA/cm2.Furthermore,the Zn//MnO2/CNT full cell retains a specific capacity of 127.2 mAh/g after 1000 cycles at 1 A/g,with 97.8%capacity retention. 展开更多

Unlike conventional electrochromic devices,Zinc anode-based electrochromic devices(ZECDs)ensure excellent charge balance between the electrochromic layer and Zn anode during the coloring/bleaching by reversible metal deposition/stripping on the Zn anode.Meanwhile,the inherent potential difference between the metal anode and the electrochromic layer can drive the spontaneous coloration/bleaching of ZECDs,featuring energy retrieval functionality.This review discusses the working mechanisms,performance indexes of ZECDs,and the impact of material selection on ZECD performance.Furthermore,we comprehensively summarize the latest research progress of ZECDs in energy storage,smart windows,and multicolor displays.We argue that using high-transparency zinc mesh,additive manufacturing processes,and self-healing electrochromic materials can significantly advance the commercialization of large-area ZECDs.Finally,“electrode-free”device structures,renewable or replaceable electrolytes,and strategies to suppress zinc dendrites are prospected to overcome cost-effectiveness and lifespan issues of ZECDs.This review aims at enabling more efficient and advanced ZECDs for multifunctional applications. 展开更多

The outstanding performance of O3-type NaNi1/3Fe1/3Mn1/3O2(NFM111)at both high and low temperatures coupled with its impressive specific capacity makes it an excellent cathode material for sodium-ion batteries.However,its poor cycling,owing to highpressure phase transitions,is one of its disadvantages.In this study,Cu/Ti was introduced into NFM111 cathode material using a solidphase method.Through both theoretically and experimentally,this study found that Cu doping provides a higher redox potential in NFM111,improving its reversible capacity and charge compensation process.The introduction of Ti would enhance the cycling stability of the material,smooth its charge and discharge curves,and suppress its high-voltage phase transitions.Accordingly,the NaNi0.27Fe0.28Mn0.33Cu0.05Ti0.06O2sample used in the study exhibited a remarkable rate performance of 142.97 mAh·g-1at 0.1 C(2.0-4.2 V)and an excellent capacity retention of 72.81%after 300 cycles at 1C(1C=150 mA·g-1). 展开更多

The stability of cathode materials is a crucial factor that influence the overall performance of aqueous batteries.Electrolyte greatly influences on the stability of cathode material due to the complexed electrochemical-chemical reactions at the interfaces.Therefore,electrolyte engineering is a direct and powerful way to solve various problems at aqueous electrolyte interfaces.In this review article,we firstly summarized the fading mechanisms of different kinds of state-ofthe-art aqueous battery cathodes including manganese/vanadium-based material,chalcogen and halogen materials,Prussian blue analogues,and Ni(OH)2cathodes.Afterward,we reviewed recent progresses on electrolyte engineering on the stability of cathode materials such as bulk electrolyte modification,electrolyte additives,water-in-salt electrolytes,and hydrogel electrolytes.Finally,we proposed the issues that should be concerned in future electrolyte design for highly state aqueous battery cathodes. 展开更多
