Most representatively, high-voltage ester-based electrolytes required by the cathodes present poor interfacial compatibility with the anodes due to unstable solid electrode interphase(SEI). Herein, Fe S@N,S-C(spindle-like Fe S nanoparticles individually encapsulated in N,S-doped carbon) with excellent structural stability is synthesized as a potential sodium anode material. It exhibits exceptional interfacial stability in ester-based electrolyte(1 M NaClO_(4) in ethylene carbonate/propylene carbonate with 5% fluoroethylene carbonate) with long-cycling lifespan(294 days) in Na|Fe S@N,S-C coin cell and remarkable cyclability in pouch cell(capacity retention of 82.2% after 170 cycles at 0.2 A g^(-1)).DFT calculation reveals that N,S-doping on electrode surface could drive strong repulsion to solvated Na_(2) and preferential adsorption to ClO_(4)^(-) anion, guiding the anion-rich inner Helmholtz plane.Consequently, a robust SEI with rich inorganic species(NaCl and Na_(2)O) through the whole depth stabilizes the electrode–electrolyte interface and protects its integrity. This work brings new insight into the role of electrode’s surface properties in interfacial compatibility that can guide the design of more versatile electrodes for advanced rechargeable metal-ion batteries.展开更多

In this work, we focus on the development and challenge of solid-state Li-air batteries(SSLABs). The rise of different types of SSEs, interfacial compatibility and verifiability in SSLABs are presented. The corresponding strategies and prospects of SSLABs are also proposed. In particular, combining machine learning method with experiment and in situ(or operando)techniques is imperative to accelerate the development of SSLABs.展开更多

文摘Solid polymer electrolytes(SPEs)with high ionic conductivity are desirable for solid-state lithium metal batteries(SSLMBs)to achieve enhanced safety and energy density.Incorporating nanofillers into a polymeric matrix to develop nanocomposite solid electrolytes(NCSEs)has become a promising method for improving the ionic conductivity of the SPEs.Here,a novel ZIF-8-functionalized NCSE was prepared for high-temperature S SLMB s using an in situ radical polymerization method.It is found that the ZIF-8 nanoparticles could reduce the crystallinity of polymer segments and offer a Lewis acid surface that promotes the dissociation of lithium bis(trifluoromethanesulfonyl)imide(LiTFSI)and stabilizes the TFSI^(-) anion movement.Thus,the as-prepared NCSE exhibits an outstanding ionic conductivity of 1.63×10^(-3)S·cm^(-1),an electrochem ical stability window of 5.0 V at 80℃,and excellent interface compatibility with lithium metal anode with a stable polarization over 2000 h.Furthermore,the assembled SSLMBs with LiFePO_(4)cathode show dendrite-free Li-metal surface,good rate capability,and stable cycling stability with a capacity retention of 70%over 1000 cycles at a high temperature of 80℃.This work provides valuable insights into promoting the ionic conductivity of SPEs.

文摘Li-air batteries have attracted extensive attention because of their ultrahigh theoretical energy density. However, the potential safety hazard of flammable organic liquid electrolytes hinders their practical applications. Replacing liquid electrolytes with solidstate electrolytes(SSEs) is expected to fundamentally overcome the safety issues. In this work, we focus on the development and challenge of solid-state Li-air batteries(SSLABs). The rise of different types of SSEs, interfacial compatibility and verifiability in SSLABs are presented. The corresponding strategies and prospects of SSLABs are also proposed. In particular, combining machine learning method with experiment and in situ(or operando)techniques is imperative to accelerate the development of SSLABs.

文摘Wood-plastic composites(WPCs)combine the advantages of plastics and lumber,however,their progress is slowed by limitations resulting from the properties of plant-based materials(PBMs),the most critical of which is insufficient thermal stability.The temperature boundary for processing of WPCs is 200℃,as higher temperatures induce PBMs’degradation,yielding odor,uncontrolled darkening,porosity generation,and loss of WPCs’mechanical performance.Going beyond the framework of composites’science and taking a transdisciplinary look at processing degradation leads to very different conclusions.The food sector makes the best of PBMs’degradation,yielding not only indispensable feed but often works of art.Drawing from its experience with the desire to go beyond the state-of-the-art,WPCs need a paradigm shift considering processing degrada-tion.The presented paper proposes the pathway against the flow.Instead of avoiding processing degradation,deliberately inducing and employing it with all the benefits,pushing WPCs toward sustainability by maximizing resource efficiency.Exceeding the temperature limit will enable the use of engineering plastics,which outperform commodity types.Considering PBMs,it will not only unleash the true potential of phytochemicals but also take advantage of the compounds yet to be generated in situ during processing degradation,enriching WPCs with benefits known from the food sector.

文摘With the increased penetration of energy storage devices in daily life,safety hazard and energy density issues are attracting greater and greater interest.Conventional liquid electrolytes suffer from leakage,flammability,gas evolution,dendrite hazards,and so on,especially when matching with high-energy-density metal anodes.Though solid-state electrolytes(SSEs)are promising candidates for the next-generation safe and high energy density energy storage system,individual SSE fails to meet the asynchronous demands of cathode and anode,because of their intrinsic solid chemistry properties.Among numerous modified approaches related to SSEs chemistry,asymmetric SSEs(ASSEs)which have more than one SSE and multilayer structure take advantage of individual SSE layers and complement each other’s disadvantages,showing Janus abilities.However,there are few reviews about ASSEs.Also,the problem of interface compatibility the between different electrolytes as well as the interface of electrodes and electrolytes is hindering the development of ASSEs.This review comprehensively outlines the state of the art of ASSEs.Additionally,it summarizes the advantages and functions of ASSEs with the unique structure for different energy storage.Furthermore,the interfacial compatibility and corresponding evaluation methods are discussed.Finally,an outlook on how ASSEs will develop in the future energy storage applications is proposed.

文摘Room temperature sodium-sulfur(Na-S)batteries,known for their high energy density and low cost,are one of the most promising next-generation energy storage systems.However,the polysulfide shuttling and uncontrollable Na dendrite growth as well as safety issues caused by the use of organic liquid electrolytes in Na-S cells,have severely hindered their commercialization.Solid-state electrolytes instead of liquid electrolytes are considered to be the most direct and effective solution to solve the above problems.However,its practical application is still greatly challenged due to the poor interfacial compatibility between the all-solid-state electrolytes and the anode/cathode,ionic conductivity,and the shuttle effect caused by the presence of liquid phase in the quasi-solid-state electrolytes.This paper presents a comprehensive review of solid-state Na-S batteries from the perspective of regulating interfacial compatibility and improving ionic conductivity as well as suppressing polysulfide shuttle.According to different components,solid-state electrolytes were divided into five categories:solid inorganic electrolytes,solid polymer electrolytes,polymer/inorganic solid hybrid electrolytes,gel polymer electrolytes,and liquid–solid inorganic hybrid electrolytes.Finally,the prospect of developing high performance solid-state electrolytes to improve the cycling stability of room temperature Na-S cells is envisaged.

文摘Composite polymer electrolytes(CPEs)have attracted much attention for high energy density solid-state lithium-metal batteries owing to their flexibility,low cost,and easy scale-up.However,the unstable Li/CPE interface is always challengeable for the practical utilization of CPEs.Herein,a polymer interlayer containing K+prepared by ultraviolet(UV)-curing precursor solution is coated on Li surface to stabilize the interface between poly(vinylidene difluoride)(PVDF)composite electrolytes and Li anode.Benefiting from the physical barrier of the interlayer,the continuous decomposition of PVDF is restrained and the intimate contact between electrode and electrolyte is also achieved to reduce the interface impedance.Moreover,the added K+is utilized to further regulate smooth Li deposition.As a consequence,the symmetric Li|Li cell with coated Li demonstrates steady cycling at 0.4 mAh·cm^(-2) and a high critical current density of 1 mA·cm^(-2).The assembled Li|LiFePO_(4) cell presents outstanding cycling stability(capacity retention of 90%after 400 cycles at 1 C)and good rate performance.The associated pouch cell performs impressive flexibility and safety.This work provides a convenient strategy to achieve stable Li/PVDF interface for high-performance PVDF-based solid state Li metal batteries.

文摘As an emerging new type of battery chemistry,the anion shuttle battery(ASB),based on the shuttling and storage of anions,is considered a sustainable alternative to gigawatt-scale energy storage due to the associated resource abundance,low cost,high safety,and high energy density.Although significant progress has been achieved,practical applications of ASBs are still hindered by tough challenges,such as short lifetime,limited reversible capacity,and low Coulombic efficiency.Therefore,it is very necessary to design and explore new electrolyte systems with high electrochemical/chemical stability,sufficient compatibility towards electrodes,and excellent kinetics/reversibility for anion electrochemical reactions.Here,we review the recent achievements and main challenges in developing electrolytes for ASBs,which include solid,non-aqueous,and aqueous electrolytes.We mainly focus on the unique properties and basic principles of designing these electrolytes,and their various performance parameters.Perspectives on design strategies for ASB electrolytes are also presented,which could facilitate the development of advanced ASBs for grid-scale energy storage.
