| 1 | Lithium–matrix composite anode protected by a solid electrolyte layer for stable lithium metal batteries显示文摘Lithium (Li) metal with an ultrahigh specific theoretical capacity and the lowest reduction potential is strongly considered as a promising anode for high-energy-density batteries. However, uncontrolled lithium dendrites and infinite volume change during repeated plating/stripping cycles hinder its practical applications immensely. Herein, a house-like Li anode (housed Li) was designed to circumvent the above issues. The house matrix was composed of carbon fiber matrix and affords a stable structure to relieve the volume change. An artificial solid electrolyte layer was formed on composite Li metal, just like the roof of a house, which facilitates uniform Li ions diffusion and serves as a physical barrier against electrolyte corrosion. With the combination of solid electrolyte layer and matrix in the composite Li metal anode, both dendrite growth and volume expansion are remarkably inhibited. The housed Li|LiFePO4 batteries exhibited over 95% capacity retention after 500 cycles at 1.0 C in coin cell and 85% capacity retention after 80 cycles at 0.5 C in pouch cell. The rationally combination of solid electrolyte layer protection and housed framework in one Li metal anode sheds fresh insights on the design principle of a safe and long-lifespan Li metal anode for Li metal batteries. | Xin Shen Xinbing Cheng Peng Shi Jiaqi Huang Xueqiang Zhang Chong Yan Tao Li Qiang Zhang | 2019 | Journal of Energy Chemistry2019，28，10： | 23 |
| 2 | Dendrite-free all-solid-state lithium batteries with lithium phosphorous oxynitride-modified lithium metal anode and composite solid electrolytes显示文摘Dendrite formation on lithium (Li) metal anode is a key issue which hinders the development of rechargeable Li battery seriously. A novel method for suppress!ng Li dendrites via using Li phosphorous oxynitride (UPON) modified Li anode and Li1.5Al0.5Ge1.5(PO4)3-poly(ethylene oxide)(Li bistrifluoromethane-sulfonimide)(LAGP-PEO(LiTFSI)) composite solid electrolyte in all-solid-state Li battery is proposed, and the effect of the thickness of UPON on Li anode performarice is also studied. LiPON film with a thickness of 500 nm exhibits satisfactory interface property between Li metal anode and the LAGP-PEO(LiTFSI) solid electrolyte. The LiPON film provides a uniform Li^+ flux across the interface and effectively inhibits the formation of Li dendrites in all-solid-state Li batteries. The assembled all-solid-state Li cell Li(LiPON)/LAGP-PEO(LiTFSI)/LiFePO4 delivers an initial discharge capacity of 152.4 mAh·g^-1 and exhibits good cycling stability and rate performanee at 50 ℃. | Chunhua Wang Guoliang Bai Yifu Yang Xingjiang Liu Huixia Shao | 2019 | Nano Research2019，12，1： | 8 |
| 3 | Towards high-performance lithium metal anodes via the modification of solid electrolyte interphases显示文摘Li metal has been regarded as one of the most promising anodes for high-energy-density storage systems due to its high theoretical capacity and lowest electrochemical potential.Unfortunately,an unstable and non-uniform solid electrolyte interphase(SEI)deriving from the spontaneous reaction between Li metal anode and electrolyte causes uneven Li deposition,resulting in the growth of Li dendrites and low Coulombic efficiency,which have greatly hindered the practical application of Li metal batteries.Thus,the construction of a stable SEI is an effective approach to suppress the growth of Li dendrites and enhance the electrochemical performances of Li metal anode.In this review,we firstly introduce the formation process of inferior SEI of Li metal anode and the corresponding challenges caused by the unstable SEI.Next,recent progresses to modify SEI layer through the regulation of electrolyte compositions and exsitu protective coating are summarized.Finally,the remained issues,challenges,and perspectives are also proposed on the basis of current research status and progress. | Zhen Hou Jiaolong Zhang Wenhui Wang Qianwen Chen Baohua Li Chaolin Li | 2020 | Journal of Energy Chemistry2020，29，6： | 8 |
| 4 | Realizing high performance of solid-state lithium metal batteries by flexible ceramic/polymer hybrid solid electrolyte显示文摘Ceramic electrolytes(CEs)and solid polymer electrolytes(SPEs)are considered to be effective methods to suppress the growth of lithium dendrites.But the inferior wettability of CEs and the low ionic conductivity of SPEs limit their applications.Zhang and colleagues report in Advanced Materials that flexible ceramic/polymer hybrid solid electrolyte—prepared by in situ coupling reaction—has great promise for high-performance Li metal batteries(LMBs).Ultrahigh energy density of LMBs is catching worldwide attention,which are 2 to 6 times higher than that of lithium-ion batteries(LIBs)[1]. | Cheng-Lin Yan | 2020 | Rare Metals2020，39，5： | 6 |
| 5 | The origin of sulfuryl-containing components in SEI from sulfate additives for stable cycling of ultrathin lithium metal anodes显示文摘In the light of wireless and non-fossil society based on portable electronics, electric vehicles, and smart grids, secondary batteries with higher energy density, faster charge, and safer operation are pursued persistently [1]. Nowadays, commercial lithium(Li)-ion batteries have been practically applied in our daily life. However,the energy density of Li-ion batteries based on intercalation chemistry is approaching to the theoretical value due to the limited specific capacity of graphite anode(372 mA h g-1) [2]. | Jin-Xiu Chen Xue-Qiang Zhang Bo-Quan Li Xin-Meng Wang Peng Shi Wancheng Zhu Aibing Chen Zhehui Jin Rong Xiang Jia-Qi Huang Qiang Zhang | 2020 | Journal of Energy Chemistry2020，29，8： | 5 |
| 6 | Protection of Li metal anode by surface-coating of PVDF thin film to enhance the cycling performance of Li batteries显示文摘Lithium metal, the ideal anode material for next-generation high-energy batteries, suffers from the severe safety problem of Li dendrites. Herein, we report a simple approach to effectively maintain the morphology of Li-metal anode and enhance the cycling performance of Li batteries by surface coating of a porous polyvinylidene fluoride (PVDF) thin film. In symmetrical cells testing, the cells with the Li@PVDF electrode display stable cycling performance more than 1300 h (650 cycles) at the current density of 0.5 mA/cm^2 with a stripping/plating capacity of 0.5 mAh/cm^2. The results with full cells employing Li@PVDF anode and LiFePO_4 cathode show a good cycling ability with a capacity retention of 80.0% after 500 cycles at 4 C and an excellent rate capability with a high capacity of 78.4 mAh/g even at a high rate of 10 C. | Zhenguang Gao Shaojian Zhang Zhigen Huang Yanqiu Lu Weiwei Wang Kai Wang Juntao Li Yao Zhou Ling Huang Shigang Sun | 2019 | Chinese Chemical Letters2019，30，2： | 5 |
| 7 | Phase-field simulation of secondary dendrite growth in directional solidification of binary alloys显示文摘Phase field method was used to simulate the effect of grains orientation angle θ_(11) and azimuth θ_A of non-preferentially growing dendrites on the secondary dendrites of preferentially growing dendrites. In the simulation process, two single-factor influence experiments were designed for columnar crystal structures. The simulation results showed that, when θ_(11) < 45o and θ_A < 45o, as θ_(11) was enlarged, the growth direction of the secondary dendrites on the preferentially growing dendrites at the converging grain boundary(GB) presented an increasing inclination to that of preferentially growing dendrites; with increasing θ_A, the growth direction of the secondary dendrites on the preferentially growing dendrites at the converging GB exhibited greater deflection,and the secondary dendrites grew with branches; the secondary dendrites on the preferentially growing dendrites at diverging GBs grew along a direction vertical to the growth direction of the preferentially growing dendrites.When θ_A = 45o and θ_(11) = 45o, the secondary dendrites grew in a direction vertical to the growth direction of preferentially growing dendrites. The morphologies of the dendrites obtained through simulation can also be found in metallographs of practical solidification experiments. This implies that the effect of a grain's orientation angle and azimuth of non-preferentially growing dendrites on the secondary dendrites of preferentially growing dendrites does exist and frequently appears in the practical solidification process. | Li Feng Ni-ni Lu Ya-long Gao Chang-sheng Zhu Jun-he Zhong Rong-zhen Xiao | 2019 | China Foundry2019，16，2： | 4 |
| 8 | Interfacial Engineering Strategy for High-Performance Zn Metal Anodes显示文摘Due to their high safety and low cost,rechargeable aqueous Zn-ion batteries(RAZIBs)have been receiving increased attention and are expected to be the next generation of energy storage systems.However,metal Zn anodes exhibit a limited-service life and inferior reversibility owing to the issues of Zn dendrites and side reactions,which severely hinder the further development of RAZIBs.Researchers have attempted to design high-performance Zn anodes by interfacial engineering,including surface modification and the addition of electrolyte additives,to stabilize Zn anodes.The purpose is to achieve uniform Zn nucleation and flat Zn deposition by regulating the deposition behavior of Zn ions,which effectively improves the cycling stability of the Zn anode.This review comprehensively summarizes the reaction mechanisms of interfacial modification for inhibiting the growth of Zn dendrites and the occurrence of side reactions.In addition,the research progress of interfacial engineering strategies for RAZIBs is summarized and classified.Finally,prospects and suggestions are provided for the design of highly reversible Zn anodes. | Bin Li Xiaotan Zhang Tingting Wang Zhangxing He Bingan Lu Shuquan Liang Jiang Zhou | 2022 | Nano-Micro Letters2022，14，1： | 3 |
| 9 | Regulating the growth of lithium dendrite by coating an ultra-thin layer of gold on separator for improving the fast-charging ability of graphite anode显示文摘With the ever-growing application of lithium-ion batteries(LIBs), their fast-charging technology has attracted great interests of scientists. However, growth of lithium dendrites during fast charge of the bat teries with high energy density may pose great threats to the operation and cause serious safety issues Herein, we prepared a functional separator with an ultra-thin(20 nm) layer of Au nanoparticles deposited by evaporation coating method which could regulate growth direction and morphology of the lithium dendrites, owing to nearly zero overpotential of lithium meal nucleation on lithiated Au. Once the Li den drites are about to form on the graphite anode during fast charging(or lithiation), they plate predomi nantly on the Au deposited separator rather than on the graphite. Such selective deposition does no compromise the electrochemical performance of batteries under normal cycling. More importantly, i enables the better cycling stability of batteries at fast charge condition. The Li/Graphite cells with Au nanoparticles coated separator could cycle stably with a high areal capacity retention of 90.5% over 95 cycles at the current density of 0.72 m A cm^(-2). The functional separator provides an effective strategy to adjust lithium plating position at fast charge to ensure high safety of batteries without a compromise on the energy density of LIBs. | Shuaishuai Yan Xiaoxia Chen Pan Zhou Peican Wang Hangyu Zhou Weili Zhang Yingchun Xia Kai Liu | 2022 | Journal of Energy Chemistry2022，31，4： | 2 |
| 10 | Nondestructive effect of the cusp magnetic field on the dendritic microstructure during the directional solidification of Nickel-based single crystal superalloy显示文摘The mechanical-property improvement of directionally-solidified Nickel-based single crystal(SC)superalloy with the single-direction magnetic fields is limited by their destructiveness on the dendritic microstructure.Here,the work present breaks through the bottleneck.It shows that the application of the cusp magnetic field(CMF)ensures that the dendrites are not destroyed.This feature embodies that the primary dendrite trunks arrange regularly and orderly,as well the secondary dendrite arms grow symmetrically.By contrast,both the unidirectional transverse and longitudinal magnetic field destroy the dendrite morphology,and there are a number of stray grains near the totally-re melted interface.The nondestructive effect is achieved mainly by the combined action of the thermoelectromagnetic force on the dendrites and thermoelectromagnetic convection in the melt during directional solidification.The investigation should contribute a new route for dramatically and effectively improving the crystal quality and mechanical properties of the directionally-solidified alloys. | Xiaotan Yuan Tao Zhou Weili Ren Jianchao Peng Tianxiang Zheng Long Hou Jianbo Yu Zhongming Ren Peter K.Liaw Yunbo Zhong | 2021 | Journal of Materials Science & Technology2021，，3： | 2 |
| 11 | 构建富氟杂化界面实现水性锌电池负极的防腐和均匀锌沉积显示文摘使用低成本、高安全性的水系电解液使二次锌金属电池(AZMBs)成为大规模储能系统是最有前途的选择.然而,锌金属负极在水系电解液中热力学稳定性较差,严重阻碍了AZMBs的实际应用.在此,我们通过在锌表面涂覆氟化石墨并利用氟化石墨和锌之间原位的界面反应开发了一种富氟的杂化人工固体电解质界面来解决上述问题.疏水的氟化石墨可以有效地限制电解液和电极之间的接触,从而显著提高锌负极的抗腐蚀能力.同时,由氟化石墨和锌原位反应生成的ZnF_(2)共同组成的富氟杂化界面可以促进Zn2+的脱溶剂化作用,并均匀化锌离子通量,从而有效地抑制了副反应发生和枝晶生长.因此,在苛刻的测试条件下(10 mA cm^(−2),1 mA h cm^(−2)和30 mA cm^(−2),10 mA h cm^(−2)),对称电池可以分别稳定地循环1400和200小时以上,远远超过了裸锌的性能.此外,使用载量为6 mg cm^(−2)的MnO_(2)正极组装的Zn/MnO_(2)全电池在1 A g^(−1)的条件下经过2000次循环,仍能保持80%以上的容量.本文提出的这种构建富氟杂化ASEI的方法可以为设计高性能AZMBs提供一种有效的潜在策略. | 王乐泉 张隆 孟宇寰 张逸翔 康峻铭 李华晶 张佳佳 赵则栋 卢红斌 | 2023 | Science China Materials2023，66，12： | 1 |
| 12 | In-situ chemical conversion film for stabilizing zinc metal anodes显示文摘Zinc metal anodes face several challenges,including the uncontrolled formation of dendrites,hydrogen evolution,and corrosion,which seriously hinder their application in practice.To address the above problems such as dendrite formation and corrosion,we present a simple and applicable immersion method that enables in situ formation of a zinc phytate(PAZ)coating on the surface of commercial Zn flakes via a substitution reaction.This protective coating mitigates corrosion of zinc flakes by the electrolyte,reduces the interfacial impedance,and accelerates the migration kinetics of zinc ions.Besides,this method can preferentially expose the(002)crystal plane with strong atomic bonding,which not only improves the corrosion resistance of the zinc flake,but can also guide the parallel deposition of zinc ions along the(002)crystal plane and reduce the formation of dendrites.Benefiting from the above advantages,the PAZ@Zn‖Cu half-cell has shown over 900 cycles with average coulombic efficiency(CE)of99.81%at 4 mA cm^(-2).Besides,the PAZ@Zn‖PAZ@Zn symmetric cell operate stably for>1000 h at5 mA cm^(-2)and>340 h at 10 mA cm^(-2).Furthermore,we demonstrated that this in situ chemical treatment enables the formation of a robust,well-bound protective coating.This method provides insights for advancing the commercialization of zinc anodes and other metal anodes. | Hao Fu Qing Wen Pei-Yao Li Zhen-yu Wang Zhen-jiang He Cheng Yan Jing Mao Kehua Dai Xia-hui Zhang Jun-chao Zheng | 2022 | Journal of Energy Chemistry2022，31，10： | 1 |
| 13 | Amyotrophic lateral sclerosis as a synaptopathy显示文摘The synapse is an incredibly specialized structure that allows for the coordinated communication of information from one neuron to another. When assembled into circuits, steady streams of excitatory and inhibitory synaptic activity shape neural outputs. At the organismal level, ensembles of neural networks underlie behavior, emotion and memory. Disorder or dysfunctions of synapses, a synaptopathy, may underlie a host of developmental and degenerative neurological conditions. There is a possibility that amyotrophic lateral sclerosis may be a result of a synaptopathy within the neuromotor system. To this end, particular attention has been trained on the excitatory glutamatergic synapses and their morphological proxy, the dendritic spine. The extensive detailing of these dysfunctions in vulnerable neuronal populations, including corticospinal neurons and motor neurons, has recently been the subject of original research in rodents and humans. If amyotrophic lateral sclerosis is indeed a synaptopathy, it is entirely consistent with other proposed pathogenic mechanisms – including glutamate excitotoxicity, accumulation of misfolded proteins and mitochondrial dysfunction at distal axon terminals(cortico-motor neuron and neuromuscular). Further, although the exact mechanism of disease spread from region to region is unknown, the synaptopathy hypothesis is consistent with emerging die-forward evidence and the prion-like propagation of misfolded protein aggregates to distant neuronal populations. Here in this mini-review, we focus on the timeline of synaptic observations in both cortical and spinal neurons from different rodent models, and provide a conceptual framework for assessing the synaptopathy hypothesis in amyotrophic lateral sclerosis. | Matthew J.Fogarty | 2019 | Neural Regeneration Research2019，14，2： | 1 |

| 15 | Chitosan derived carbon membranes as protective layers on zinc anodes for aqueous zinc batteries显示文摘Aqueous zinc batteries with low cost and inherent safety are considered to be the most promising energy storage devices.However,they suffer from poor cycling stability and low coulombic efficiencies caused by the adverse zinc dendrites on the anodes during the discharging/charging processes.Chitosan is a kind of natural amino polysaccharide,which is rich in nitrogen and carbon.When sintered at high temperatures,carbon membranes have been achieved with excellent conductivity and graphitization degree,which could enhance the ability to induce zinc ion uniform deposition to some extent.In this work,a type of carbon membrane using chitosan as raw materials has been fabricated by sintering,and then assembled as the protect layers in aqueous zinc batteries.The results show that the samples could retain smoother surfaces when adopting the sintering temperature of 800℃,and the assembled batteries are able to achieve about 700 h at a current density of 0.25m A·cm^(-2),which is far longer than those of the similar batteries without any carbon membranes. | Haichao Li Zengwu Wei Yu Xia Junshan Han Xing Li | 2023 | International Journal of Minerals,Metallurgy and Materials2023，30，4： | 0 |
| 16 | Speciation and Mobility of Arsenic in Agricultural Lime Speciation显示文摘Agricultural liming materials are often applied to the adjustment of soil acidity and the improvement of plant growth and microbial functionality.Relatively low-grade agricultural lime was found to contain up to 125 mg/kg arsenic(As),which is above any fertilizing materials’ toxicity threshold limit.Several techniques were employed to determine the speciation of the arsenic.Results from microprobe analyses suggest that minor minerals such as black and brown dendrites are the source of high arsenic concentrations in the samples.X-ray fluorescence spectroscopy provided further information that ferrihydrite and crystalline goethite are responsible for hosting the high concentration of arsenic with Fe/As molar ratio in around 100.A five-step sequential extraction demon- | Michael Kersten | 2009 | 地学前缘2009，16，S1： | 0 |
| 17 | An Interface-Fitted Finite Element Level Set Method with Application to Solidification and Solvation显示文摘A new finite element level set method is developed to simulate the interface motion.The normal velocity of the moving interface can depend on both the local geometry,such as the curvature,and the external force such as that due to the flux from both sides of the interface of a material whose concentration is governed by a diffusion equation.The key idea of the method is to use an interface-fitted finite element mesh.Such an approximation of the interface allows an accurate calculation of the solution to the diffusion equation.The interface-fitted mesh is constructed from a base mesh,a uniform finite element mesh,at each time step to explicitly locate the interface and separate regions defined by the interface.Several new level set techniques are developed in the framework of finite element methods.These include a simple finite element method for approximating the curvature,a new method for the extension of normal velocity,and a finite element least-squares method for the reinitialization of level set functions.Application of the method to the classical solidification problem captures the dendrites.The method is also applied to the molecular solvation to determine optimal solute-solvent interfaces of solvation systems. | Bo Li John Shopple | 2011 | Communications in Computational Physics2011，10，6： | 0 |

| 19 | Carbon-based interface engineering and architecture design for high-performance lithium metal anodes显示文摘Metallic lithium(Li)is considered the“Holy Grail”anode material for the nextgeneration of Li batteries with high energy density owing to the extraordinary theoretical specific capacity and the lowest negative electrochemical potential.However,owing to inhomogeneous Li-ion flux,Li anodes undergo uncontrollable Li deposition,leading to limited power output and practical applications.Carbon materials and their composites with controllable structures and properties have received extensive attention to guide the homogeneous growth of Li to achieve high-performance Li anodes.In this review,the correlation between the behavior of Li anode and the properties of carbon materials is proposed.Subsequently,we review emerging strategies for rationally designing high-performance Li anodes with carbon materials,including interface engineering(stabilizing solid electrolyte interphase layer and other functionalized interfacial layer)and architecture design of host carbon(constructing three-dimension structure,preparing hollow structure,introducing lithiophilic sites,optimizing geometric effects,and compositing with Li).Based on the insights,some prospects on critical challenges and possible future research directions in this field are concluded.It is anticipated that further innovative works on the fundamental chemistry and theoretical research of Li anodes are needed. | Na Zhu Yuxiang Yang Yu Li Ying Bai Junfeng Rong Chuan Wu | 2024 | Carbon Energy2024，6，1： | 0 |
| 20 | Leap of Li Metal Anodes from Coin Cells to Pouch Cells:Challenges and Progress显示文摘Li metal anodes have attracted tremendous attention in the last decade because of their high theoretical capacities and low electrochemical potentials.However,until now,there has only been limited success in improving the interfacial and structural stabilities and in realizing the highly controllable and large-scale fabrication of this emerging material;these limitations have posed great obstacles to further performing fundamental and applied studies in Li metal anodes.In this review,we focus on summarizing the existing challenges of Li metal anodes based on the leap from coin cells to pouch cells and on outlining typical methods for designing Li metal anodes on demand;we controllably engineer their surface protection layers and structure sizes by encapsulating structured Li metal inside a variety of synthetic protection layers.We aim to provide a comprehensive understanding and serve as a strategic guide for designing and fabricating practicable Li metal anodes for use in pouch batteries.Challenges and opportunities regarding this burgeoning field are critically evaluated at the end of this review. | Qian Wang Tiantian Lu Yuanbin Xiao Jianyang Wu Lixiang Guan Lifeng Hou Huayun Du Huan Wei Xiaoda Liu Chengkai Yang Yinghui Wei Henghui Zhou Yan Yu | 2023 | Electrochemical Energy Reviews2023，6，1： | 0 |
