| 1 | Revisiting Scientific Issues for Industrial Applications of Lithium–Sulfur Batteries显示文摘Inspired by high theoretical energy density(-2600 W h kg^(-1))and cost-effectiveness of sulfur cathode,lithium–sulfur batteries are receiving great attention and considered as one of the most promising next-generation high-energy-density batteries.However,over the past decades,the energy density and reliable safety levels as well as the commercial progress of lithium-sulfur batteries are still far from satisfactory due to the disconnection and huge gap between fundamental research and practical application. | Bo Liu Ruyi Fang Dong Xie Wenkui Zhang Hui Huang Yang Xia Xiuli Wang Xinhui Xia Jiangping Tu | 2018 | Energy & Environmental Materials2018，1，4： | 9 |

| 3 | A Perspective on Energy Densities of Rechargeable Li-S Batteries and Alternative Sulfur-Based Cathode Materials显示文摘Lithium-ion battery has reached its capacity and energy density limits.In the past decade,significant efforts have been taken to explore new electrode materials that have the potential to enable high-energy-density battery systems.Among them,elemental sulfur is one of the high-capacity cathode candidates and has been studied intensively over the past decade.The formation of lithium polysulfides in ethereal liquid electrolyte upon cycling results in several challenges such as active material dissolution,shuttle effect,and limited cycle life.Although some approaches have been developed to overcome these issues,the attainable energy densities of lithium–sulfur(Li-S)batteries seem to be low.The main reason is largely due to the high electrolyte/sulfur(E/S)ratios used in the sulfur cathode.This perspective provides new insights on the energy density analysis of sulfur cathode.The“average mass density”of sulfur cathode is found to be a useful parameter for this purpose.Some emerging alternative sulfur-based cathode materials such as organopolysulfides and metal polysulfides which possess unique properties and performances are presented.They are promising to overcome the intrinsic issues associated with elemental sulfur cathode and enable truly high-energy-density Li-S battery systems. | Wei Guo Yongzhu Fu | 2018 | Energy & Environmental Materials2018，1，1： | 8 |
| 4 | Progresses in Sustainable Recycling Technology of Spent Lithium-Ion Batteries显示文摘The number of lithium-ion batteries(LIBs)is steadily increasing in order to meet the ever-growing demand for sustainable energy and a high quality of life for humankind.At the same time,the resulting large number of LIB waste certainly poses safety hazards if it is not properly disposed of and will seriously harm the environment due to its inherent toxicity due to the use of toxic substances.Moreover,the consumption of many scarce precious metal resources is behind the mass production of batteries.In the light of severe environmental,resources,safety and recycling problems,recycling spent LIBs have become an essential urgently needed action to achieve sustainable social development.This review therefore critically analyses the value and the need for recycling of spent LIBs from a variety of resources and the environment.A range of existing technologies for recycling and reusing spent LIBs,such as pretreatment,pyrometallurgy,hydrometallurgy,and direct recycled methods,is subsequently summarized exclusively.In addition,the benefits and problems of the methods described above are analyzed in detail.It also introduces recycling progress of other LIB components,such as anodes,separators,and electrolytes,as well as the high-value cathode.Finally,the prospects for recycling LIBs are addressed in four ways(government,users,battery manufacturers,and recyclers).This review should contribute to the development of the recycling of used LIBs,particularly in support of industrialization and recycling processes. | Kaidi Du Edison Huixiang Ang Xinglong Wu Yichun Liu | 2022 | Energy & Environmental Materials2022，5，4： | 7 |

| 6 | Electrochemical Kinetic Modulators in Lithium–Sulfur Batteries:From Defect-Rich Catalysts to Single Atomic Catalysts显示文摘Lithium–sulfur batteries exhibit unparalleled merits in theoretical energy density(2600 W h kg^(-1))among next-generation storage systems.However,the sluggish electrochemical kinetics of sulfur reduction reactions,sulfide oxidation reactions in the sulfur cathode,and the lithium dendrite growth resulted from uncontrollable lithium behaviors in lithium anode have inhibited high-rate conversions and uniform deposition to achieve high performances.Thanks to the“adsorption-catalysis”synergetic effects,the reaction kinetics of sulfur reduction reactions/sulfide oxidation reactions composed of the delithiation of Li_(2)S and the interconversions of sulfur species are propelled by lowering the delithiation/diffusion energy barriers,inhibiting polysulfide shuttling.Meanwhile,the anodic plating kinetic behaviors modulated by the catalysts tend to uniformize without dendrite growth.In this review,the various active catalysts in modulating lithium behaviors are summarized,especially for the defect-rich catalysts and single atomic catalysts.The working mechanisms of these highly active catalysts revealed from theoretical simulation to in situ/operando characterizations are also highlighted.Furthermore,the opportunities of future higher performance enhancement to realize practical applications of lithium–sulfur batteries are prospected,shedding light on the future practical development. | Jing Zhang Caiyin You Hongzhen Lin Jian Wang | 2022 | Energy & Environmental Materials2022，5，3： | 5 |
| 7 | Designing Advanced Aqueous Zinc-Ion Batteries:Principles,Strategies,and Perspectives显示文摘Aqueous zinc-ion batteries(AZIBs)are an appealing battery system due to their low cost,intrinsic safety,and environmental-friendliness,while their application is plagued by the obstacles from the cathode,electrolyte,and zinc anode.Summarizing the design principles and strategies toward the optimization of cathode,electrolyte,and zinc anode is crucial for the development of AZIBs.Herein,we present a comprehensive analysis of the design principles and promising strategies toward the improvement of AZIBs.Firstly,the various reaction mechanisms are summarized and the existing issues associated with the cathode,electrolyte,and zinc anode are discussed to guide the rational design of AZIBs.Subsequently,we provide an in-depth and comprehensive discussion on the design principles and strategies for the electrodes/electrolyte/separator optimization,and analyze the advantages and disadvantages of various strategies.Importantly,the design principles and strategies of the newly appeared conversion-type AZIBs,such as Zn-S battery and Zn-Se battery,are also discussed and analyzed.The effect of design strategies on the electrochemical performance and the relationship between the current issues and strategies are also unveiled in detail.Finally,some research trends and perspectives are provided for designing better AZIBs. | Yan Li Zhouhao Wang Yi Cai Mei Er Pam Yingkui Yang Daohong Zhang Ye Wang Shaozhuan Huang | 2022 | Energy & Environmental Materials2022，5，3： | 4 |
| 8 | Bimetallic Metal-Organic Framework with High-Adsorption Capacity toward Lithium Polysulfides for Lithium–sulfur Batteries显示文摘The practical application of Li-S batteries is largely impeded by the“shuttle effect”generated at the cathode which results in a short life cycle of the battery.To address this issue,this work discloses a bimetallic metal-organic framework(MOF)as a sulfur host material based on Al-MOF,commonly called(Al)MIL-53.To obtain a high-adsorption capacity to lithium polysulfides(Li_(2)S_(x),4≤x≤8),we present an effective strategy to incorporate sulfiphilic metal ion(Cu^(2+))with high-binding energy to Li_(2)S_(x) into the framework.Through a one-step hydrothermal method,Cu^(2+) is homogeneously dispersed in Al-MOF,producing a bimetallic Al/Cu-MOF as advanced cathode material.The macroscopic Li2S4 solution permeation test indicates that the Al/Cu-MOF has better adsorption capacity to lithium polysulfides than monometallic Al-MOF.The sulfur-transfusing process is executed via a melt-diffusion method to obtain the sulfur-containing Al/CuMOF(Al/Cu-MOF-S).The assembled Li-S batteries with Al/Cu-MOF-S yield improved cyclic performance,much better than that of monometallic AlMOF as sulfur host.It is shown that chemical immobilization is an effective method for polysulfide adsorption than physical confinement and the bimetallic Al/Cu-MOF,formed by incorporation of sulfiphilic Cu^(2+) into porous MOF,will provide a novel and powerful approach for efficient sulfur host materials. | Pengbiao Geng Meng Du Xiaotian Guo Huan Pang Ziqi Tian Pierre Braunstein Qiang Xu | 2022 | Energy & Environmental Materials2022，5，2： | 4 |

| 13 | Enabling Argyrodite Sulfides as Superb Solid-State Electrolyte with Remarkable Interfacial Stability Against Electrodes显示文摘While argyrodite sulfides are getting more and more attention as highly promising solid-state electrolytes(SSEs)for solid batteries,they also suffer from the typical sulfide setbacks such as poor electrochemical compatibility with Li anode and high-voltage cathodes and serious sensitivity to humid air,which hinders their practical applications.Herein,we have devised an effective strategy to overcome these challenging shortcomings through modification of chalcogen chemistry under the guidance of theoretical modeling.The resultant Li_(6.25)PS_(4)O_(1.25)Cl_(0.75)delivered excellent electrochemical compatibility with both pure Li anode and high-voltage LiCoO_(2)cathode,without compromising the superb ionic conductivity of the pristine sulfide.Furthermore,the current SSE also exhibited highly improved stability to oxygen and humidity,with further advantage being more insulating to electrons.The remarkably enhanced compatibility with electrodes is attributed to in situ formation of helpful electrolyte–electrode interphases.The formation of in situ anode–electrolyte interphase(AEI)enabled stable Li plating/stripping in the Li|Li_(6.25)PS_(4)O_(1.25)Cl_(0.75)|Li symmetric cells at a high current density up to 1 mA cm^(-2)over 200 h and 2 mA cm^(-2)for another 100 h.The in situ amorphous nano-film cathode–electrolyte interphase(CEI)facilitated protection of the SSE from decomposition at elevated voltage.Consequently,the synergistic effect of AEI and CEI helped the LiCoO_(2)|Li_(6.25)PS_(4)O_(1.25)Cl_(0.75)|Li full-battery cell to achieve markedly better cycling stability than that using the pristine Li_(6)PS_(5)Cl as SSE,at a high area loading of the active cathode material(4 mg cm^(-2))in type-2032 coin cells.This work is to add a desirable SSE in the argyrodite sulfide family,so that high-performance solid battery cells could be fabricated without the usual need of strict control of the ambient atmosphere. | Hongjie Xu Guoqin Cao Yonglong Shen Yuran Yu Junhua Hu Zhuo Wang Guosheng Shao | 2022 | Energy & Environmental Materials2022，5，3： | 3 |
| 14 | Recent Advances in Effective Reduction of Graphene Oxide for Highly Improved Performance Toward Electrochemical Energy Storage显示文摘The demand for high-quality graphene from various applications promotes the exploration of various synthesis methods such as chemical vapor deposition,chemical reduction of graphite oxide,liquid-phase exfoliation,and electrochemical exfoliation.Among those,chemical treatments for the production of reduced graphene oxide(RGO)dictate the current technologies for mass production of graphene powder.However,such conventional chemical reduction methods are rather ineffective in removing oxygen-containing functional groups from graphene oxide(GO),with resultant RGO products containing high level of structural defects.This leads to significantly damaged crystallinity and drastically lowered electric and thermal conductivity,which is probably the main bottleneck to limit the performance of RGO-based materials.Great efforts such as thermal reduction,microwave-irradiation reduction,or other novel reduction methods(e.g.,photoreduction)have been developed to repair defects in RGO materials.This perspective review is to outline the latest advances toward effective reduction of GO for significantly enhanced properties.We demonstrate that effectively repaired RGO with large specific surface area and highly improved crystallinity is key to highly improved electric and thermal conductivity,thus leading to significantly enhanced properties essential for chemical energy storage devices. | Peng Zhang Zhi Li Shijie Zhang Guosheng Shao | 2018 | Energy & Environmental Materials2018，1，1： | 3 |
| 15 | Hierarchical Bimetallic Selenides CoSe_(2)–MoSe_(2)/rGO for Sodium/Potassium-Ion Batteries Anode: Insights into the Intercalation and Conversion Mechanism显示文摘As anode materials for high-performance sodium-ion batteries and potassium-ion batteries,bimetallic selenides have attracted great concern due to their relatively high electrical conductivity and electrochemical activity.However,the formidable challenge in the reaction process is the large volume change,leading to the structural collapse of material,and eventually the decline in electrochemical performance.Herein,a composite of hierarchical CoSe_(2)–MoSe_(2) tubes anchored on reduced graphene oxide nanosheets(CoSe_(2)–MoSe_(2)/rGO)is designed by an in situ hydrothermal selenization treatment.Benefiting from the synergistic effects between CoSe_(2) and MoSe_(2),unique hierarchical structure,and effective reduced graphene oxide coating,the CoSe_(2)–MoSe_(2)/rGO exhibited improved reaction kinetics and structural stability,and thus good electrochemical properties.A combination mechanism of intercalation and conversion of CoSe_(2)–MoSe_(2)/rGO by forming NaxCoSe_(2) and Mo_(15)Se_(19) as intermediate states is put forward on the basis of in situ and ex situ XRD analyses. | Yanan Xu Xiaofeng Liu Hang Su Shan Jiang Jianmin Zhang Dan Li | 2022 | Energy & Environmental Materials2022，5，2： | 3 |
| 16 | Scalable Membraneless Direct Liquid Fuel Cells Based on a Catalyst-Selective Strategy显示文摘This perspective presents a membraneless direct liquid fuel cell(DLFC)concept based on a catalyst-selective strategy.The membraneless DLFCs are operated at low temperatures by employing a non-precious cathode catalyst with a high catalytic selectivity.The uniqueness is that the inexpensive cathode catalyst only catalyzes the oxygen reduction reaction but does not catalyze the oxidation reaction of a specific fuel.Therefore,during the operation of DLFCs,the liquid fuel can enter the cathode freely without any concern of fuel crossover.This catalyst-selective approach tactfully avoids the use of high-cost or technically unviable ion-exchange polymer membranes in DLFCs.The catalyst-selective operating principle also overcomes the scalability issue of the traditional laminar-flow membraneless DLFCs.Through a proper management of the anode and cathode catalysts in the cell,a variety of inexpensive,renewable alcohols,and small-molecule organics can be employed as anode fuels.This innovative approach of membraneless alkaline DLFCs offers a great opportunity for the development of inexpensive energy-generation systems for both mobile and stationary applications.In addition to summarizing the principle and the research progress of the unique membraneless DLFC platform,the challenges and future research directions are presented. | Xingwen Yu Arumugam Manthiram | 2018 | Energy & Environmental Materials2018，1，1： | 3 |
