Solid-state lithium batteries are being pursued as next-generation energy-storage systems since they promise improved safety and higher energy density by pairing nonflammable inorganic solid electrolytes with lithium-metal anodes[1-3].Among various solid electrolytes,inorganic ceramics are particularly attractive because they combine high Li+conductivity,a wide electrochemical stability window,and sufficient mechanical rigidity.This rigidity would be expected to resist lithium penetration during electrodeposition[4].However,lithium filaments can still penetrate dense ceramic electrolytes,causing internal short circuits.This apparent contradiction raises a fundamental question:how can soft lithium propagate through a hard ceramic electrolyte? 展开更多

Driven by global strategies for decarbonization and carbon neutrality,renewable-energy intermittency underscores the importance of large-scale electrochemical energy storage(EES).Rechargeable batteries,as the core components within EES,have long been restricted by limitations intrinsic to conventional dilute electrolytes,including narrow electrochemical stability windows,poor low-temperature performance,high flammability,and weak compatibility with high-voltage electrodes.Regulation of solvation structure in electrolytes has emerged as a key approach to overcome these bottlenecks.This review highlights five representative strategies:highly concentrated electrolytes,localized high-concentration electrolytes,weakly solvating electrolytes,hydrogen-bond regulated electrolytes,and eutectic electrolytes.These strategies have greatly advanced Li-ion,Na-ion,Zn-ion,Li-S,Li-air,and Na-S batteries.Finally,challenges ahead and opportunities in solvationstructure design are summarized to guide innovative and sustainable progress in next-generation energy storage technologies. 展开更多

Rechargeable aluminum-ion batteries are emerging as promising next-generation energy storage systems,benefiting from the high mass/volumetric energy density,low cost,and intrinsic safety of Al anodes.However,their practical deployment is hindered by the limitations of conventional non-aqueous electrolytes,including moisture/oxygen sensitivity,cost,and toxicity.Aqueous aluminum-ion batteries(AAIBs)offer a compelling alternative,with advantages in cost,safety,and environmental impact.Yet,the scarcity of suitable electrolytes,particularly those capable of supporting reversible three-electron Al3+/Al redox chemistry,poses a major obstacle to commercialization.Meanwhile,developing low-cost,chemically/electrochemically stable electrolytes capable of functioning across diverse temperatures remains a critical challenge and a central research direction for advancing AAIB technology.This review comprehensively surveys advances in AAIB electrolytes,focusing on high-concentration electrolyt systems for electrochemical stability,hydrogel electrolytes that mitigate degradation through solid-phase confinement,and hydrated eutectic electrolytes for wide-temperature operation.In particular,we delve into the latest innovations in AAIB electrolyte design,provide a comprehensive perspective on current opportunities and unresolved hurdles,discuss the strengths,limitations,and potential solutions for each electrolyte type,while outlining future pathways for the development of AAIB electrolytes. 展开更多

The high voltage of Li||LiCoO2 battery can increase the energy density.However,the cycling performance associated with cathode structural stability remains challenging.To address this question,we proposed an electrolyte strategy for improving the performance of 4.6 V Li||LiCoO2 battery by using trimethylsilyl isocyanate(TMIS)as electrolyte additive.The trimethylsilyl group of TMIS can trap HF while the isocyanate group brings polyamide components to the CEI and the SEI.By the synergistic action,the Co3+dissolution problem of the LiCoO2 cathode was effectively curbed.Furthermore,TMIS regulates the construction of anion-dominated LiF-rich SEI by influencing the solvation structure of Li+.As expected,the 4.6 V Li||LiCoO2 battery with TMIS retains 77.9% initial capacity after 200 cycles at 0.5 C. 展开更多

Lithium(Li)metal batteries hold great promise due to their high energy density,yet severe side reactions between routine organic electrolytes and the Li metal anode hinder their practical implementation.Elucidating the fundamental mechanisms that govern electrolyte stability on the Li metal anode is crucial to stabilizing the electrolyte-anode interface and promoting the practical applications of Li metal batteries.Herein,the regulation mechanism of the anode surface on the electrolyte stability is revealed at the atomic scale by density functional theory calculations.Indicated by the changes in the lowest unoccupied molecular orbital(LUMO)energy levels,solvents exhibit markedly lower reductive stability on Li metal surfaces compared with bulk molecules,making them more prone to parasitic reactions.Two major components in solid electrolyte interphase(SEI),i.e.,LiF and Li2O,can passivate the solvent reduction through an average increase of 1.46 eV in their LUMO energy levels.The LUMO energy changes are further correlated with the Li-O distance between the solvents and SEI components,exhibiting an approximately linear relationship.This work reveals the role of the SEI in protecting Li metal anodes from electrolyte corrosion and identifies key factors regulating solvent stability,providing fundamental insights for the rational design of advanced electrolytes and robust SEI for practical Li metal batteries. 展开更多

Li metal batteries(LMBs),owing to their high theoretical specific energy,are considered a crucial development direction for future high-energy-density battery systems.However,the high reactivity of the Li metal anode leads to extreme electrochemical and chemical instability at the interface with the electrolyte.This instability triggers detrimental effects,including Li dendrite growth,repeated cracking and reformation of the solid electrolyte interphase(SEI),and continuous irreversible consumption of both active Li and electrolyte.Therefore,designing high-performance electrolytes to precisely regulate interfacial chemistry has become one of the core strategies for advancing the practical application of LMBs.Significant progress has recently been made in stabilizing the Li metal-electrolyte interface(Li-electrolyte interface)through strategies including additives,weakly solvating electrolytes(WSEs),high-concentration/localized high-concentration electrolytes(HCEs/LHCEs),and novel molecular design.Nevertheless,these advanced strategies and their corresponding stabilization mechanisms have not yet been systematically organized.To address this gap,this review focuses on four core electrolyte design strategies and systematically summarizes their mechanisms for stabilizing the Li-electrolyte interface.Building on this foundation,it discusses the inherent limitations of individual electrolyte design strategies.It then focuses on the potential of synergistic electrolyte design to achieve a more electrochemically stable Li-electrolyte interface.Finally,it proposes future research directions requiring key focus for existing electrolyte design strategies. 展开更多

Lithium-air batteries are considered a strong candidate for next-generation electrochemical energy storage due to their exceptionally high theoretical energy density.However,the inherent issues of liquid electrolytes,such as flammability and uncontrolled lithium dendrite growth,severely restrict the safety and practical application of lithium-air batteries.Therefore,developing polymer electrolytes that combine high safety,good mechanical properties,and favorable interfacial compatibility is a critical path toward realizing practical solid-state lithium-air batteries.This review summarizes the fundamental characteristics,preparation methods,and performance in LABs of three categories of polymer electrolytes:solid polymer electrolytes,gel polymer electrolytes,and composite polymer electrolytes.A particular emphasis is placed on reviewing the roles and mechanisms of active and inert fillers in improving the polymer-filler interface,enhancing ion transport and mechanical strength,and reinforcing interfacial stability.The review concludes by summarizing the major current challenges and proposing future research directions,aiming to promote the system integration and engineering application of solid-state lithium-air batteries toward achieving high energy density and long cycle life. 展开更多

Despite the high energy density,lithium metal batteries(LMBs)face significant cycling instability and safety challenges,especially at subzero temperatures.Herein,we report a rationally designed lowconcentrated electrolyte system that employs a low-freezing-point diluent to compress solvation sheaths,enabling the formation of a compact anion-dominated solvation structure that enhances interfacial stability and safety.Molecular dynamics reveal the unique solvation structure with close packing of anions in this low-concentration electrolyte from the micro-mesoscopic scale.The optimized electrolyte combines cost-effectiveness,superior wettability,intrinsic nonflammability,and high stability,concurrently promoting a hybrid organic-inorganic solid electrolyte interphase(SEI)and cathode electrolyte interphase(CEI)for uniform lithium deposition.As a result,the Li‖LiFePO4(LFP)full cells demonstrate stable cycling for 700 cycles at the current density of 4 C.Remarkably,the electrolyte demonstrates exceptional low-temperature performance,indicating broad operational viability.This work provides a promising electrolyte design strategy that addresses both safety and excellent electrochemical performance in high-energy-density metal-based batteries,including but not restricted to Li,Na,K and Zn multivalent ion systems. 展开更多

The quest for sustainable and efficient energy storage solutions has led to significant advancements in the field of solid-state batteries,with a particular focus on solid-state electrolytes(SSEs)especially highly ionic conductive sulfide and halide materials.However,the air instability of these SSEs not only limits their mass production but also poses environmental and safety risks.Herein,the damage of humid-air exposure on the structure and electrochemical properties of Li5.5PS4.5Cl0.8Br0.7 and Li3InCl6 is evaluated,and a subsequent heat treatment is proposed and proven effective to recover the damage,whose mechanisms are pinpointed through XRD data with Retvield refinement.For the exposed samples,a lattice contraction occurs as the hydrolysis reaction caused by H2O from humid air severely damages the structure,which impedes lithium-ion transport.After heat treatment,a lattice rearrangement can rebuild sufficient lithium-ion pathway in the material,leading to the greatly improved ionic conductivity.As a result,the treated electrolytes provide greatly promoted ionic conductivity(from 0.95 mS/cm to 1.8 mS/cm for Li3InCl6,from 1.24 S/cm to 7.04 S/cm for Li5.5PS4.5Cl0.8Br0.7).More importantly,ASSBs employed with the treated electrolytes achieve outstanding long-term cycling and rate performance,even guarantee considerable capacity output of~217 and~159 mAh/g under extreme conditions of 60 and-20℃,illustrating significantly improved electrochemical reaction kinetics and the impressive reliability of the heat treatment method. 展开更多

Solid-state batteries that present lower risk factors and higher energy density are promising for advanced energy storage and applications.In particular,solid-state electrolytes(SSEs)are the critical components that responsible for ionic transport between negative electrodes and positive electrodes.It is crucial to fundamentally understand the ionic transport models and behaviors in the SSEs,with purpose of enhancing ion transport rate and stability of SSEs.To rationally improve the solid-state ion transport behavior of electrolytes,this review summarizes recent progresses on the transport principles and multiscale characterization methods of ion transport in SSEs,including traditional electrochemical methods,frequency-dependent spectroscopy,two-dimensional morphological imaging and three-dimensional morphological imaging.It is emphasized that combination of multiscale and multiple methods would be a developing trend for fundamentally understanding the mechanism of ion transport in SSEs.According to comprehensive transport principle and behaviors,hierarchical fillers are designed for composite electrolytes with fast ionic transport abilities.The remaining challenges for establishing advanced multiscale characterization methods are also discussed. 展开更多

Aqueous alkali metal-ion batteries(AAMIBs)have been recognized as emerging electrochemical energy storage technologies for grid-scale applications owning to their intrinsic safety,cost-effectiveness,and environmental sustainability.However,the practical application of AAMIBs is still severely constrained by the tendency of aqueous electrolytes to freeze at low temperatures and decompose at high temperatures,limiting their operational temperature range.Considering the urgent need for energy systems with higher adaptability and resilience at various application scenarios,designing novel electrolytes via structure modulation has increasingly emerged as a feasible and economical strategy for the performance optimization of wide-temperature AAMIBs.In this review,the latest advancement of wide-temperature electrolytes for AAMIBs is systematically and comprehensively summarized.Specifically,the key challenges,failure mechanisms,correlations between hydrogen bond behaviors and physicochemical properties,and thermodynamic and kinetic interpretations in aqueous electrolytes are discussed firstly.Additionally,we offer forward-looking insights and innovative design principles for developing aqueous electrolytes capable of operating across a broad temperature range.This review is expected to provide some guidance and reference for the rational design and regulation of widetemperature electrolytes for AAMIBs and promote their future development. 展开更多

Compared to currently commercialized lithium-ion batteries,which use flammable organic liquid electrolytes and low-energy-density graphite anodes,solid-state lithium-metal batteries(SSLMBs)offer enhanced energy density and improved safety,making them promising alternatives for next-generation rechargeable batteries[1].As a crucial component of these batteries,solid-state electrolytes—divided into inorganic solid ceramic electrolytes(SCEs)and organic solid polymer electrolytes(SPEs)—are vital for lithium-ion transport and inhibiting lithium dendrite growth.Among them,SCEs exhibit high ionic conductivity,excellent mechanical properties,and outstanding electrochemical and thermal stability.Nevertheless,their brittleness,interfacial challenges with electrodes,and the requirement for high stacking pressure during battery operation significantly hinder their scalable application.In comparison,SPEs are more favourable for manufacturing due to their flexibility and good interfacial compatibility with electrodes[2].Despite these advantages,SPEs still face significant challenges in achieving practical application.Firstly,typical SPEs,such as poly(ethylene oxide)(PEO),poly(vinylidene fluoride)(PVDF),and poly(ethylene glycol)diacrylate(PEGDA),are characterized by high crystallinity,which causes polymer chains to be tightly packed and rigid.This restricts the segmental motion within the SPEs,resulting in low ionic conductivity.Secondly,compared to lithium ions,anions with large ionic radii and low charge density typically form weaker interactions with the polymer chains,which facilitates their mobility and results in a low lithium-ion transference number(tt).Thirdly,the weak interactions between polymer chains in typical SPEs lead to a low elastic modulus,which in turn compromises their poor mechanical strength. 展开更多

Lithium-ion batteries(LIBs),while dominant in energy storage due to high energy density and cycling stability,suffer from severe capacity decay,rate capability degradation,and lithium dendrite formation under low-temperature(LT)operation.Therefore,a more comprehensive and systematic understanding of LIB behavior at LT is urgently required.This review article comprehensively reviews recent advancements in electrolyte engineering strategies aimed at improving the low-temperature operational capabilities of LIBs.The study methodically examines critical performance-limiting mechanisms through fundamental analysis of four primary challenges:insufficient ionic conductivity under cryogenic conditions,kinetically hindered charge transfer processes,Li+transport limitations across the solidelectrolyte interphase(SEI),and uncontrolled lithium dendrite growth.The work elaborates on innovative optimization approaches encompassing lithium salt molecular design with tailored dissociation characteristics,solvent matrix optimization through dielectric constant and viscosity regulation,interfacial engineering additives for constructing low-impedance SEI layers,and gel-polymer composite electrolyte systems.Notably,particular emphasis is placed on emerging machine learning-guided electrolyte formulation strategies that enable high-throughput virtual screening of constituent combinations and prediction of structure-property relationships.These artificial intelligence-assisted rational design frameworks demonstrate significant potential for accelerating the development of next-generation LT electrolytes by establishing quantitative composition-performance correlations through advanced data-driven methodologies. 展开更多

Commercial carbonate electrolytes suffer from ion transport difficulty in bulk electrolytes and interphase at low temperatures,bringing challenges to the application of lithium-ion batteries(LIBs)at low temperatures.Herein,the ester solvent of methyl propionate(MP)with low melting point and low viscosity was used to tackle ion transport difficulty in electrolytes.Fluorinated ester was further added to accelerate interfacial transport through intermolecular interactions.The influence of fluorinated esters with different fluorination degrees on the solvation structure of electrolytes and the performance of batteries was further studied.As a result,methyl pentafluoropropionate(M5F)with five fluorine atoms was selected for its optimal interactions with both Li+and MP solvent in the primary solvation structure,contributing to desired solvation structure for fast interfacial transport.The LiFePO4(LFP)||graphite cell with LiFSI-MP-M5F electrolyte exhibited a high cyclability of 85.8%after 120 cycles and retained 81.2%of room-temperature capacity when charged and discharged at−30℃.1 Ah LFP||graphite pouch cell with high cathode loading(20 mg/cm2)in LiFSI-MP-M5F electrolyte exhibited 0.85 Ah capacity when charged and discharged at−20℃.This work provides a guidance for electrolyte design by synergistic fluorinated and non-fluorinated solvents for LIBs at low-temperature application. 展开更多

Aqueous zinc-ion batteries(AZIBs)hold great promise for next-generation energy storage but face challenges such as Zn dendrite growth,side reactions,and limited performance at low temperatures.Here,we propose an electrolyte design strategy that reconstructs the hydrogenbond network through the synergistic effect of glycerol(GL)and methylsulfonamide(MSA),enabling the formation of a(100)-oriented Zn anode.This design significantly broadens the operating current and temperature windows of AZIBs.As a result,Zn||Zn symmetric cells exhibit remarkable cycling stability,achieving 4,000 h at 1 mA cm-2and 600 h at 40 mA cm-2(both at 1 mAh cm-2capacity);even at-20℃,Zn||Zn symmetric cells deliver ultra-stable cycling for over 5,400 h.Furthermore,Zn||VO2full cells retain 77.3%of their capacity after 2,000 cycles at 30°C with a current density of 0.5 A g-1and 85.4%capacity retention after 2,000 cycles at-20°C and 0.25 A g-1.These results demonstrate a robust pathway for enhancing the practicality and low-temperature adaptability of AZIBs. 展开更多

Oxygen(O)doping is a promising strategy for enhancing the air stability and lithium metal compatibility of sulfide solid electrolytes(SSEs).However,the impact of various O sources on the structure and properties of SSEs remains unclear.In this study,we synthesized a series of O-doped electrolytes,Li5.5PS4.5-xOxCl1.5(LPSCOx,0.1≤x≤0.5),using Li2O and P2O5as O sources,and systematically investigated their differences in structure,air stability,and electrochemical properties.O preferentially substitutes sulfur(S)at the 16e site and begins to replace S at the 4d site once a certain O concentration is reached.Notably,the P2O5-doped electrolytes(P-LPSCOx)exhibit a greater oxygen tolerance content(0.24)at the 16e site,along with better air stability,higher ionic conductivity,and superior lithium metal compatibility.XRD,SEM,and XPS analyses reveal that the P2O5-doped electrolytes exhibit larger cell parameters,higher densification,and fewer side reactions with lithium metal compared to the Li2O-doped counterparts.This study provides valuable insights into the development of high-performance O-doped sulfide electrolytes. 展开更多

Halide solid state electrolytes(SSEs)have attracted significant attention due to their outstanding advantages of better cathodic stability and higher ionic conductivity.However,the most halide SSEs are unstable against lithium,preventing their direct use with lithium anodes and thus sacrificing the energy density of all solid-state lithium batteries(AsSLBs),which significantly limits their application.Conventional strategies,such as employing Li-In anode or sulfide interface layer,suffer from reduced energy density or interfacial incompatibility.Employing a halide of the same family as the interface layer,instead of the chemically dissimilar sulfide SSEs,is expected to resolve the interfacial compatibility problem.Herein,we propose an all-halide double composite electrolyte(LTLC-LZC),where Li2ZrCl6(LZC)serves as the bulk layer and Li0.388Ta0.238La0.475Cl3(LTLC)functions as the anode-side interfacial contact layer.The two halide electrolytes exhibit excellent chemical compatibility and comparable processability,enabling facile cold-pressed bilayer assembly.Compared with single-layer LZC,the LTLC-LZC electrolyte significantly enhances interfacial stability and ionic conductivity.Therefore,Li|LTLC-LZC|Li symmetric cells cycle stably for over 2500 h,while Li|LTLC-LZC|NCM622 full cells deliver high initial coulombic efficiency and maintain~100%coulombic efficiency during cycling.This work provides a viable pathway toward practical high-energy halide-based AsSLBs. 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

Reversible modulation of the transmittance in electrochromic devices(ECDs)holds tremendous potential for energy-saving windows.The choice of electrolyte significantly influences the optical modulation,coloring response speed,coloring efficiency,and cycling stability of electrochromic devices.Moreover,traditional electrolytes are prone to instability under extreme temperature conditions,leading to device failure and severely limiting the widespread application of smart electrochromic windows.This study introduces LiCl water-in-salt electrolyte(WiSE)into tungsten oxide-based ECDs.LiCl WiSE exhibits wide-temperature tolerance and excellent ion conductivity.Therefore,the constructed tungsten oxide ECD demonstrates large optical modulation(76.2%@700 nm),fast response time(tc=2.0 s,tb=1.8 s),and high cycling stability(95.8%retention after 1000 cycles).Especially,it operates efficiently over a wide temperature range of-30~80℃.This research provides a new approach for electrolyte selection in the fabrication of high-performance,wide-temperature-tolerant ECDs. 展开更多

Coupling lithium metal with gel polymer electrolytes(GPEs)has been demonstrated as an effective strategy to enable stable lithium metal batteries(LMBs).However,the current design of GPEs faces difficulties in simultaneously achieving satisfactory mechanical properties and efficient and selective ion transport.Here,we present the fabrication of ultrastrong and hierarchically nanoporous cellulose gel electrolytes via poly(ionic liquid)-induced interfacial coacervation of cellulose nanofibrils.The nanofibrils GPE with a cascade ion-conduction network spanning from molecular-scale channels to mesopores enables dualmode Li+transport through nanoconfinement and interstitial ion hopping.This mechanism effectively blocks anion movement while achieving selective Li+transport with a high transference number of 0.7 and a high ionic conductivity of 0.65 mS cm-1.The GPE enables stable cycling of high mass loading(LiFePO4,16 mg cm-2)LMBs and high-temperature(80℃)LMBs.Specifically,the LMB with a high LiFePO4loading of 12 mg cm-2delivers stable cycling life over 600 cycles,maintaining 87%capacity retention.Furthermore,the assembled 635 mAh pouch full cell demonstrates excellent stability with a high capacity retention of 91.7%after 1500 cycles.This study offers a novel strategy for the development of robust and ion-selective GPEs for stable LMBs. 展开更多
