    364-379页
    查看更多>>摘要：The safety and durability of lithium-ion batteries under mechanical constraints depend significantly on electrochemical,thermal,and mechanical fields in applications.Characterizing and quantifying the multi-field coupling behaviors requires interdisciplinary efforts.Here,we design experiments under mechanical constraints and introduce an in-situ analytical framework to clarify the complex interaction mechanisms and coupling degrees among multi-physics fields.The proposed analytical framework inte-grates the parameterization of equivalent models,in-situ mechanical analysis,and quantitative assess-ment of coupling behavior.The results indicate that the significant impact of pressure on impedance at low temperatures results from the diffusion-controlled step,enhancing kinetics when external pres-sure,like 180 to 240 kPa at 10 ℃,is applied.The diversity in control steps for the electrochemical reaction accounts for the varying impact of pressure on battery performance across different temperatures.The thermal expansion rate suggests that the swelling force varies by less than 1.60％per unit of elevated temperature during the lithiation process.By introducing a composite metric,we quantify the coupling correlation and intensity between characteristic parameters and physical fields,uncovering the highest coupling degree in electrochemical-thermal fields.These results underscore the potential of analytical approaches in revealing the mechanisms of interaction among multi-fields,with the goal of enhancing battery performance and advancing battery management.

    407-427页
    查看更多>>摘要：Sodium-ion batteries(SIBs)with advantages of abundant resource and low cost have emerged as promis-ing candidates for the next-generation energy storage systems.However,safety issues existing in elec-trolytes,anodes,and cathodes bring about frequent accidents regarding battery fires and explosions and impede the development of high-performance SIBs.Therefore,safety analysis and high-safety battery design have become prerequisites for the development of advanced energy storage systems.The reported reviews that only focus on a specific issue are difficult to provide overall guidance for building high-safety SIBs.To overcome the limitation,this review summarizes the recent research progress from the perspec-tive of key components of SIBs for the first time and evaluates the characteristics of various improvement strategies.By orderly analyzing the root causes of safety problems associated with different components in SIBs(including electrolytes,anodes,and cathodes),corresponding improvement strategies for each component were discussed systematically.In addition,some noteworthy points and perspectives includ-ing the chain reaction between security issues and the selection of improvement strategies tailored to dif-ferent needs have also been proposed.In brief,this review is designed to deepen our understanding of the SIBs safety issues and provide guidance and assistance for designing high-safety SIBs.

    Hollow NiMo-based nitride heterojunction with super-hydrophilic/aerophobic surface for efficient urea-assisted hydrogen production

    428-439页
    查看更多>>摘要：Hydrogen evolution reaction(HER)and urea oxidation reaction(UOR)are key reactions of the water-cycling associated catalytic process/device.The design of catalysts with a super-hydrophilic/aerophobic structure and optimized electron distribution holds great promise.Here,we have designed a three-dimensional(3D)hollow Ni/NiMoN hierarchical structure with arrayed-sheet surface based on a one-pot hydrothermal route for efficient urea-assisted HER based on a simple hydrothermal process.The Ni/NiMoN catalyst exhibits super-hydrophilic/aerophobic properties with a small droplet contact angle of 6.07° and an underwater bubble contact angle of 155.7°,thus facilitating an escape of bubbles from the electrodes.Density functional theory calculations and X-ray photoelectron spectroscopy results indi-cate the optimized electronic structure at the interface of Ni and NiMoN,which can promote the adsorp-tion/desorption of reactants and intermediates.The virtues combining with a large specific surface area endow Ni/NiMoN with efficient catalytic activity of low potentials of 25 mV for HER and 1.33 V for UOR at 10 mA cm-2.The coupled HER and UOR system demonstrates a low cell voltage of 1.42 V at 10 mA cm-2,which is approximately 209 mV lower than water electrolysis.

    查看更多>>摘要：Hydride ion(H-)conductors have drawn much attention due to their potential applications in hydride-ion-based devices.Rare earth metal hydrides(REHx)have fast H-conduction which,unfortunately,is accompanied by detrimental electron conduction preventing their application as ion conductors.Here,REHx(RE=Nd,Ce,and Pr)with varied grain sizes,rich grain boundaries,and defects have been prepared by ball milling and subsequent sintering.The electronic conductivity of the ball-milled REHx samples can be reduced by 2-4 orders of magnitude compared with the non-ball-milled samples.The relationship of electron conduction and miscrostructures in REHx is studied and discussed based on experimental data and previously-proposed classical and quantum theories.The H-conductivity of all REHx is about 10-4 to 10-3 S cm-1 at room temperature,showing promise for the development of H-conductors and their applications in clean energy storage and conversion.

    490-498页
    查看更多>>摘要：Developing efficient and durable hydrogen evolution reaction(HER)electrocatalysts is one of the most important issues for the commercialization of seawater electrolysis,but it remains challenging.Here,we report a CeO2-CoP nanoneedle array catalyst loaded on Ti mesh(CeO2-CoP/TM)with work-function-induced directional charge transport properties.The CeO2-CoP/TM catalyst showed superior HER catalytic activity and stability,with overpotentials of 41 and 60 mV to attain 10 mA cm2,in 1 M KOH and 1 M KOH+seawater electrolyte,respectively.Experimental results and theoretical calculations reveal that the work function drives the charge transfer from CeO2 to CoP,which effectively balances the electronic density of CoP and CeO2,optimizes the d-band center,and accelerates the water activation kinetics,thus enhancing the HER activity.The solar-driven water electrolysis device displays a high and stable solar-to-hydrogen conversion efficiency of 19.6％.This study offers a work function-induced directional charge transport strategy to design efficient and durable catalysts for hydrogen production.
