    查看更多>>摘要：Urea oxidation reaction(UOR)has been selected as substitution for oxygen evolution reaction ascribing to its low thermodynamic voltage as well as utilization of nickel as electrocatalyst.Herein,we report the formation of nickel single atoms(Ni-SAs)as exceptional bifunctional electrocatalyst toward UOR and hydrogen evolution reaction(HER)in urea-assisted water splitting.In UOR catalysis,Ni-SAs perform a superior catalytic performance than Ni-NP/NC and Pt/C ascribing to the formation of HOO-Ni-N4 struc-ture evidenced by in-situ Raman spectroscopy,corresponding to a boosted mass activity by 175-fold at 1.4 V vs.RHE than Ni-NP/NC.Furthermore,Ni-SAs requires only 450 mV overpotential to obtain HER current density of 500 mA cm-2.136 mA cm-2 is achieved in urea-assisted water splitting at 1.7 V for Ni-SAs,boosted by 5.7 times than Pt/C-IrO2 driven water splitting.

    Atomically dispersed Fe sites on hierarchically porous carbon nanoplates for oxygen reduction reaction

    7-15页
    查看更多>>摘要：Developing cost-effective,robust and stable non-precious metal catalysts for oxygen reduction reaction(ORR)is of paramount importance for electrochemical energy conversion devices such as fuel cells and metal-air batteries.Although Fe-N-C single atom catalysts(SACs)have been hailed as the most promising candidate due to the optimal binding strength of ORR intermediates on the Fe-N4 sites,they suffer from serious mass transport limitations as microporous templates/substrates,i.e.,zeolitic imidazolate frame-works(ZIFs),are usually employed to host the active sites.Motivated by this challenge,we herein develop a hydrogen-bonded organic framework(HOF)-assisted pyrolysis strategy to construct hierarchi-cal micro/mesoporous carbon nanoplates for the deposition of atomically dispersed Fe-N4 sites.Such a design is accomplished by employing HOF nanoplates assembled from 2-aminoterephthalic acid(NH2-BDC)and p-phenylenediamine(PDA)as both soft templates and C,N precursors.Benefitting from the structural merits inherited from HOF templates,the optimized catalyst(denoted as Fe-N-C SAC-950)dis-plays outstanding ORR activity with a high half-wave potential of 0.895 V(vs.reversible hydrogen elec-trode(RHE))and a small overpotential of 356 mV at 10 mA cm-2 for the oxygen evolution reaction(OER).More excitingly,its application potential is further verified by delivering superb rechargeability and cycling stability with a nearly unfading charge-discharge gap of 0.72 V after 160 h.Molecular dynamics(MD)simulations reveal that micro/mesoporous structure is conducive to the rapid mass transfer of O2,thus enhancing the ORR performance.In situ Raman results further indicate that the conversion of O2 to*O2-the rate-determining step(RDS)for Fe-N-C SAC-950.This work will provide a versatile strategy to construct single atom catalysts with desirable catalytic properties.

    16-22页
    查看更多>>摘要：All-inorganic CsPbIBr2 perovskite has attracted widespread attention in photovoltaic and other optoelec-tronic devices because of its superior thermal stability.However,the deposition of high-quality solution-processed CsPbIBr2 perovskite films with large thicknesses remains challenging.Here,we develop a triple-component precursor(TCP)by employing lead bromide,lead iodide,and cesium bromide,to replace the most commonly used double-component precursor(DCP)consisting of lead bromide and cesium iodide.Remarkably,the TCP system significantly increases the solution concentration to 1.3 M,leading to a larger film thickness(～390 nm)and enhanced light absorption.The resultant CsPbIBr2 films were evaluated in planar n-i-p structured solar cells,which exhibit a considerably higher optimal pho-tocurrent density of 11.50 mA cm-2 in comparison to that of DCP-based devices(10.69 mA cm-2).By adopting an organic surface passivator,the maximum device efficiency using TCP is further boosted to a record efficiency of 12.8％for CsPbIBr2 perovskite solar cells.

    Stabilizing zinc anode using zeolite imidazole framework functionalized separator for durable aqueous zinc-ion batteries

    Weisong ZhangXinyan ZhuLing KangZiyu Peng...
    23-31页
    查看更多>>摘要：Aqueous zinc-ion batteries(AZIBs)hold great promise as a viable alternative to lithium-ion batteries owing to their high energy density and environmental friendliness.However,AZIBs are consistently pla-gued by the formation of zinc dendrites and concurrent side reactions,which significantly diminish their overall service life.In this study,the glass fiber separator(GF)is modified using zeolite imidazole salt framework-8(ZIF-8),enabling the development of efficient AZIBs.ZIF-8,which is abundant in nitrogen content,efficiently regulates the desolvation of[Zn(H2O)6]2+to inhibit hydrogen production.Moreover,it possesses abundant nanochannels that facilitate the uniform deposition of Zn2+via a localized action,thereby hindering the formation of dendrites.The insulating properties of ZIF-8 help prevent Zn2+and water from trapping electron reduction at the layer surface,which reduces corrosion of the zinc anode.Consequently,ZIF-8-GF achieves the even transport of Zn2+and regulates the homogeneous deposition along the Zn(002)crystal surface,thus significantly enhancing the electrochemical performance of the AZIBs.In particular,the Zn|Zn symmetric cell with the ZIF-8-GF separator delivers a stable cycle life at 0.5 mA cm-2 of 2300 h.The Zn|ZIF-8-GF|MnO2 cell exhibits reduced voltage polarization while maintain-ing a capacity retention rate(93.4％)after 1200 cycles at 1.2 A g-1 The unique design of the modified dia-phragm provides a new approach to realizing high-performance AZIBs.

    Stabilizing perovskite precursors with the reductive natural amino acid for printable mesoscopic perovskite solar cells

    Wenjing HuJian YangChuang YangXufeng Xiao...
    32-39页
    查看更多>>摘要：Solution processability significantly advances the development of highly-efficient perovskite solar cells.However,the precursor solution tends to undergo irreversible degradation reactions,impairing the device performance and reproducibility.Here,we utilize a reductive natural amino acid,N-acetylcysteine(NALC),to stabilize the precursor solution for printable carbon-based hole-conductor-free mesoscopic perovskite solar cells.We find that I2 can be generated in the aged solution containing methylammonium iodide(MAI)in an inert atmosphere and speed up the MA-FA+(formamidinium)reac-tion which produces large-size cations and hinders the formation of perovskite phase.NALC effectively stabilizes the precursor via its sulfhydryl group which reduces I2 back to I-and provides H+.The NALC-stabilized precursor which is aged for 1440 h leads to devices with a power conversion efficiency equivalent to 98％of that for devices prepared with the fresh precursor.Furthermore,NALC improves the device power conversion efficiency from 16.16％to 18.41％along with enhanced stability under atmo-spheric conditions by modifying grain boundaries in perovskite films and reducing associated defects.

    查看更多>>摘要：Energy-storage systems and their production have attracted significant interest for practical applications.Batteries are the foundation of sustainable energy sources for electric vehicles(EVs),portable electronic devices(PEDs),etc.In recent decades,Lithium-ion batteries(LIBs)have been extensively utilized in large-scale energy storage devices owing to their long cycle life and high energy density.However,the high cost and limited availability of Li are the two main obstacles for LIBs.In this regard,sodium-ion batteries(SIBs)are attractive alternatives to LIBs for large-scale energy storage systems because of the abundance and low cost of sodium materials.Cathode is one of the most important components in the battery,which limits cost and performance of a battery.Among the classified cathode structures,layered structure materials have attracted attention because of their high ionic conductivity,fast diffusion rate,and high specific capacity.Here,we present a comprehensive review of the classification of layered structures and the preparation of layered materials.Furthermore,the review article discusses extensively about the issues of the layered materials,namely(1)electrochemical degradation,(2)irreversible structural changes,and(3)structural instability,and also it provides strategies to overcome the issues such as ele-mental phase composition,a small amount of elemental doping,structural design,and surface alteration for emerging SIBs.In addition,the article discusses about the recent research development on layered unary,binary,ternary,quaternary,quinary,and senary-based O3-and P2-type cathode materials for high-energy SIBs.This review article provides useful information for the development of high-energy lay-ered sodium transition metal oxide P2 and O3-cathode materials for practical SIBs.

    Recent advances in solving Li2CO3 problems in garnet-based solid-state battery:A systematic review(2020-2023)

    58-76页
    查看更多>>摘要：Garnet solid electrolytes are one of the most promising electrolytes for solid-state batteries.However,Li2CO3 is a critical issue that hinders the practical application of garnet-based solid-state lithium-ion bat-teries.There are two sources of Li2CO3 contamination.The main one is the aging of garnet electrolytes in the atmosphere.Garnet electrolytes can react with H2O and CO2 in the air to form Li2CO3,which reduces ion conductivity,increases electrode/garnet electrolyte interface resistance,and deteriorates the electro-chemical performance of the battery.Various strategies,such as elemental doping,grain boundary manipulation,and interface engineering,have been suggested to address these issues.The other is the passivation layer(Li2CO3,Li3N,LiOH,Li2O)formed on the surface of the lithium foil after long-term stor-age,which is ignored by most researchers.To better understand the current strategies and future trends to address the Li2CO3 problem,this perspective provides a systematic review of journals published in this field from 2020-2023.

    Powering the future:A comprehensive review on calcium-ion batteries

    Ameneh Taghavi-KahagHossein Roghani-MamaqaniMehdi Salami-Kalajahi
    77-97页
    查看更多>>摘要：Due to concerns regarding the future availability,cost,and safety of lithium in Li-ion batteries(LIBs),researchers are exploring alternative chemistries such as Na-ion,Li-S,Li-air,and multivalent ion tech-nologies.Multivalent ion technologies,which utilize divalent or trivalent ions,like Mg2+,Ca2+,and Al3+,show promise in achieving greater energy densities than LIBs due to their ability to deposit uniformly on anodes and intercalate into cathodes.While magnesium-ion batteries(MIBs)have been the primary area of research for multivalent ion batteries,the cost-effectiveness and abundance of calcium have sparked a growing interest in calcium-ion batteries(CIBs)in recent years.Compared to LIBs,CIBs have the potential to provide longer cycle life,enhanced safety,and increased energy densities.However,the development of CIBs comes with several challenges,such as finding suitable electrode and electrolyte materials that ensure the stability and safety of the battery.The primary hurdle in CIBs lies in the plating/stripping process.There is a significant hindrance preventing the occurrence of plating/stripping in CIBs,which lies in the formation of a passive layer resulting from the decomposition of the electrolyte.The objective of this article is to examine the advancements made in CIBs.Additionally,it aims to comprehen-sively assess the mechanisms and materials employed in various battery components,as well as the obstacles encountered in CIBs.This includes recent advancements in electrode materials,electrolytes,cell configurations,and the challenges and opportunities for enhancing the performance and commercial via-bility of CIBs.

    查看更多>>摘要：The liquid-cooled battery energy storage system(LCBESS)has gained significant attention due to its supe-rior thermal management capacity.However,liquid-cooled battery pack(LCBP)usually has a high sealing level above IP65,which can trap flammable and explosive gases from battery thermal runaway and cause explosions.This poses serious safety risks and challenges for LCBESS.In this study,we tested overcharged battery inside a commercial LCBP and found that the conventionally mechanical pressure relief valve(PRV)on the LCBP had a delayed response and low-pressure relief efficiency.A realistic 20-foot model of an energy storage cabin was constructed using the Flacs finite element simulation software.Comparative studies were conducted to evaluate the pressure relief efficiency and the influence on neigh-boring battery packs in case of internal explosions,considering different sizes and installation positions of the PRV.Here,a newly developed electric-controlled PRV integrated with battery fault detection is introduced,capable of starting within 50 ms of the battery safety valve opening.Furthermore,the PRV was integrated with the battery management system and changed the battery charging and discharging strategy after the PRV was opened.Experimental tests confirmed the efficacy of this method in prevent-ing explosions.This paper addresses the safety concerns associated with LCBPs and proposes an effective solution for explosion relief.

    110-119页
    查看更多>>摘要：Antimony(Sb)-based anode materials are feasible candidates for sodium-ion batteries(SIBs)due to their high theoretical specific capacity and excellent electrical conductivity.However,they still suffer from vol-ume distortion,structural collapse,and ionic conduction interruption upon cycling.Herein,a hierarchical array-like nanofiber structure was designed to address these limitations by combining architecture engi-neering and anion tuning strategy,in which SbPO4-x with oxygen vacancy nanosheet arrays are anchored on the surface of interwoven carbon nanofibers(SbPO4-x@CNFs).In particular,bulky PO43-anions miti-gate the large volume distortion and generate Na3PO4 with high ionic conductivity,collectively improv-ing cyclic stability and ionic transport efficiency.The abundant oxygen vacancies substantially boost the intrinsic electronic conductivity of SbPO4,further accelerating the reaction dynamics.In addition,hierar-chical fibrous structures provide abundant active sites,construct efficient conducting networks,and enhance the electron/ion transport capacity.Benefiting from the advanced structural design,the SbPO4-x@CNFs electrodes exhibit outstanding cycling stability(1000 cycles at 1.0 A g-1 with capacity decay of 0.05％per cycle)and rapid sodium storage performance(293.8 mA h g-1 at 5.0 A g-1).Importantly,systematic in-/ex-situ techniques have revealed the"multi-step conversion-alloying"reac-tion process and the"battery-capacitor dual-mode"sodium-storage mechanism.This work provides valuable insights into the design of anode materials for advanced SIBs with elevated stability and superior rate performance.
