1The critical role of carbon in marrying silicon and graphite anodes for high-energy lithium-ion batteries显示文摘Increasing the energy density of conventional lithium-ion batteries(LIBs)is important for satisfying the demands of electric vehicles and advanced electronics.Silicon is considered as one of the most-promising anodes to replace the traditional graphite anode for the realization of high-energy LIBs due to its extremely high theoretical capacity,although its severe volume changes during lithiation/delithiation have led to a big challenge for practical application.In contrast,the co-utilization of Si and graphite has been well recognized as one of the preferred strategies for commercialization in the near future.In this review,we focus on different carbonaceous additives,such as carbon nanotubes,reduced graphene oxide,and pyrolyzed carbon derived from precursors such as pitch,sugars,heteroatom polymers,and so forth,which play an important role in constructing micrometersized hierarchical structures of silicon/graphite/carbon(Si/G/C)composites and tailoring the morphology and surface with good structural stability,good adhesion,high electrical conductivity,high tap density,and good interface chemistry to achieve high capacity and long cycling stability simultaneously.We first discuss the importance and challenge of the co-utilization of Si and graphite.Then,we carefully review and compare the improved effects of various types of carbonaceous materials and their associated structures on the electrochemical performance of Si/G/C composites.We also review the diverse synthesis techniques and treatment methods,which are also significant factors for optimizing Si/G/C composites.Finally,we provide a pertinent evaluation of these forms of carbon according to their suitability for commercialization.We also make far-ranging suggestions with regard to the selection of proper carbonaceous materials and the design of Si/G/C composites for further development.Jingxing Wu Yinliang Cao Haimin Zhao Jianfeng Mao Zaiping Guo 2019Carbon Energy2019,1,1:18

3Recycling of mixed cathode lithium-ion batteries for electric vehicles: Current status and future outlook显示文摘Worldwide trends in mobile electrification,largely driven by the popularity of electric vehicles(EVs)will skyrocket demands for lithium-ion battery(LIB)production.As such,up to four million metric tons of LIB waste from EV battery packs could be generated from 2015 to 2040.LIB recycling directly addresses concerns over longterm economic strains due to the uneven geographic distribution of resources(especially for Co and Li)and environmental issues associated with both landfilling and raw material extraction.However,LIB recycling infrastructure has not been widely adopted,and current facilities are mostly focused on Co recovery for economic gains.This incentive will decline due to shifting market trends from LiCoO2 toward cobalt-deficient and mixed-metal cathodes(eg,LiNi1/3Mn1/3Co1/3O2).Thus,this review covers recycling strategies to recover metals in mixed-metal LIB cathodes and comingled scrap comprising different chemistries.As such,hydrometallurgical processes can meet this criterion,while also requiring a low environmental footprint and energy consumption compared to pyrometallurgy.Following pretreatment to separate the cathode from other battery components,the active material is dissolved entirely by reductive acid leaching.A complex leachate is generated,comprising cathode metals(Li+,Ni2+,Mn2+,and Co2+)and impurities(Fe3+,Al3+,and Cu2+)from the current collectors and battery casing,which can be separated and purified using a series of selective precipitation and/or solvent extraction steps.Alternatively,the cathode can be resynthesized directly from the leachate.Tyler Or Storm WDGourley Karthikeyan Kaliyappan Aiping Yu Zhongwei Chen 2020Carbon Energy2020,2,1:16
4Issues and solutions toward zinc anode in aqueous zinc-ion batteries: A mini review显示文摘Aqueous zinc-ion batteries(ZIBs)have been intensively investigated as potential energy storage devices on account of their low cost,environmental benignity,and intrinsically safe merits.With the exploitation of highperformance cathode materials,electrolyte systems,and in-depth mechanism investigation,the electrochemical performances of ZIBs have been greatly enhanced.However,there are still some challenges that need to be overcome before its commercialization.Among them,the obstinate dendrites,corrosion,and hydrogen evolution reaction(HER)on Zn anodes are critical issues that severely limit the practical applications of ZIBs.To address these issues,various strategies have been proposed,and tremendous progress has been achieved in the past few years.In this article,we analyze the origins and effects of the dendrites,corrosion,and HER on Zn anodes in neutral and mildly acid aqueous solutions at first.And then,a scientific understanding of the fundamental design principles and strategies to suppress these problems are emphasized.Apart from these,this article also puts forward some requirements for the practical applications of Zn anodes as well as several cost-effectivemodifying strategies.Finally,perspectives on the future development of Zn anodes in aqueous solutions are also briefly anticipated.This article provides pertinent insights into the challenges on anodes for the development of highperformance ZIBs,which will greatly contribute to their practical applications.Chunlin Xie Yihu Li Qi Wang Dan Sun Yougen Tang Haiyan Wang 2020Carbon Energy2020,2,4:15
5Mechanically strong and folding-endurance Ti_(3)C_(2)T_(x) MXene/PBO nanofiber films for efficient electromagnetic interference shielding and thermal management显示文摘Electromagnetic interference(EMI)shielding materials with excellent flexibility and mechanical properties and outstanding thermal conductivity have become a hot topic of research in functional composites.In this study,the“sol-gel-film conversion technique”is used to assemble polyetherimidefunctionalized Ti_(3)C_(2)T_(x) nanosheets(f-Ti_(3)C_(2)T_(x))with poly(p-phenylene-2,6-benzobisoxazole)(PBO)nanofibers(PNFs),followed by dialysis and vacuum drying to prepare f-Ti_(3)C_(2)T_(x)/PNF films with lamellar structures.When the loading of f-Ti_(3)C_(2)T_(x) is 70 wt%,the f-Ti_(3)C_(2)T_(x)/PNF film presents optimal comprehensive properties,with an EMI shielding effectiveness(SE)of 35 dB and a specific SE/thickness((SSE,SE/density)/t)of 8211 dB cm^(2)/g,a tensile strength of 125.1 MPa,an in-plane thermal conductivity coefficient(λ)of 5.82 W/(m K),and electrical conductivity of 1943 S/m.After repeated folding for 10,000 cycles,the EMI SE and the tensile strength of f-Ti_(3)C_(2)T_(x)/PNFs films still remain 33.4 dB and 116.1 MPa,respectively.Additionally,the f-Ti_(3)C_(2)T_(x)/PNF film also shows excellent thermal stability,flame retardancy,and structural stability.This would provide a novel method for the design and fabrication of multifunctional composite films and considerably expand the applications of MXene-and PNF-based composites in the fields of EMI shielding and thermal management.Lei Wang Zhonglei Ma Yali Zhang Hua Qiu Kunpeng Ruan Junwei Gu 2022Carbon Energy2022,4,2:12

7Graphitic carbon nitride (g-C3N4)-based nanosized heteroarrays: Promising materials for photoelectrochemical water splitting显示文摘Photoelectrochemical(PEC)water splitting is recognized as a sustainable strategy for hydrogen generation due to its abundant hydrogen source,utilization of inexhaustible solar energy,high-purity product,and environment-friendly process.To actualize a practical PEC water splitting,it is paramount to develop efficient,stable,safe,and low-cost photoelectrode materials.Recently,graphitic carbon nitride(g-C3N4)has aroused a great interest in the new generation photoelectrode materials because of its unique features,such as suitable band structure for water splitting,a certain range of visible light absorption,nontoxicity,and good stability.Some inherent defects of g-C3N4,however,seriously impair further improvement on PEC performance,including low electronic conductivity,high recombination rate of photogenerated charges,and limited visible light absorption at long wavelength range.Construction of g-C3N4-based nanosized heteroarrays as photoelectrodes has been regarded as a promising strategy to circumvent these inherent limitations and achieve the high-performance PEC water splitting due to the accelerated exciton separation and the reduced combination of photogenerated electrons/holes.Herein,we summarize in detail the latest progress of g-C3N4-based nanosized heteroarrays in PEC water-splitting photoelectrodes.Firstly,the unique advantages of this type of photoelectrodes,including the highly ordered nanoarray architectures and the heterojunctions,are highlighted.Then,different g-C3N4-based nanosized heteroarrays are comprehensively discussed,in terms of their fabrication methods,PEC capacities,and mechanisms,etc.To conclude,the key challenges and possible solutions for future development on g-C3N4-based nanosized heteroarray photoelectrodes are discussed.Liqun Wang Wenping Si Yueyu Tong Feng Hou Daniele Pergolesi Jungang Hou Thomas Lippert Shi Xue Dou Ji Liang 2020Carbon Energy2020,2,2:10
8Recent progress and challenges of carbon materials for Zn-ion hybrid supercapacitors显示文摘Zinc-ion hybrid supercapacitors(ZHSCs)have garnered increasing attention as promising energy storage devices in recent years,as they combine the advantages of high-energy Zn-ion batteries and high-power supercapacitors.However,the development of ZHSCs is still in its infancy and there are many bottlenecks to overcome.In particular,the challenge induced by the limited ion adsorption capability of carbon-positive electrodes severely restricts the energy density of ZHSCs.Therefore,it has become a key issue to design novel carbon-positive electrodes that enable high energy density yet do not deteriorate the intrinsic power capability and long-term durability.This study focuses on recent achievements in synthesis,morphology,and electrochemical performance of various carbon materials applied in ZHSCs.The modification strategies to optimize their electrochemical performance are briefly summarized.In addition,current challenges and future opportunities in this field are also outlined.This review will be beneficial to provide an organized framework for the research systems of carbon-positive electrodes and develop novel ZHSCs with high energy density.Qiyu Liu Haozhe Zhang Jinhao Xie Xiaoqing Liu Xihong Lu 2020Carbon Energy2020,2,4:10

10Recent advances and strategies in the stabilization of single-atom catalysts for electrochemical applications显示文摘Owing to the rapidly increasing consumption of fossil fuels,finding clean and reliable new energy sources is of the utmost importance.Thus,developing highly efficient and low-cost catalysts for electrochemical reactions in energy conversion devices is crucial.Single-atom catalysts(SACs)with maximum metal atom utilization efficiency and superior catalytic performance have attracted significant attention,especially for electrochemical reactions.However,because of the highly unsaturated coordination environment,the stability of SACs can be a challenge for practical applications.In this review,we will summarize the strategies to increase the stability of SACs and synthesizing stable SACs,as well as the application of SACs in electrochemical reactions.Finally,we offer a perspective on the development of advanced SACs through rational design and a deeper understanding of SACs with the help of in situ or operando techniques in electrochemical reactions.Junjie Li Lei Zhang Kieran Doyle-Davis Ruying Li Xueliang Sun 2020Carbon Energy2020,2,4:9

14Reaction decoupling in thermochemical fuel conversion and technical progress based on decoupling using fluidized bed显示文摘Thermochemical conversion of fuels via pyrolysis/carbonization,cracking,gasification and combustion has to involve a number of individual reactions called attribution reactions to form an intercorrelated reaction network for any conversion process.By separating one or some attribution reactions from the others to decouple their interactions existing in the reaction network,the so-called reaction decoupling enables a better understanding of the complex thermal conversion process and further the optimization of the conditions for attribution reactions as well as the entire conversion process to realize advanced performances.The dual bed conversion and two-stage conversion are the two representative types of fuel conversion technologies developed in recent years based on reaction decoupling.Many technical advantages have been proven for such decoupling fuel conversion technologies,such as poly-generation of products,low-cost production of high-grade products,elimination of undesirable products or pollutants,easy operation and control,and so on.The treated fuels with decoupling conversion technologies mainly include solid biomass and coal,as well as liquid petroleum oil.This paper is devoted to reiteration of the reaction decoupling concept and further to reviewing the research,developments and successful applications of several decoupling fuel conversion technologies of two such types by using fluidized bed as their major reactors.Zhennan Han Sulong Geng Xi Zeng Shipei Xu a Ping An Jiguang Cheng Jun Yang Feng Li Suyi Zhang Miao Liu Guoqing Guan Guangwen Xu 2018Carbon Resources Conversion2018,1,2:8
15Multifunctional roles of carbon-based hosts for Li-metal anodes:A review显示文摘With its high theoretical capacity,lithium(Li)metal is recognized as the most potential anode for realizing a high-performance energy storage system.A series of questions(severe safety hazard,low Coulombic efficiency,short lifetime,etc.)induced by uncontrollable dendrites growth,unstable solid electrolyte interface layer,and large volume change,make practical application of Li-metal anodes still a threshold.Due to their highly appealing properties,carbon-based materials as hosts to composite with Li metal have been passionately investigated for improving the performance of Li-metal batteries.This review displays an overview of the critical role of carbon-based hosts for improving the comprehensive performance of Li-metal anodes.Based on correlated mainstream models,the main failure mechanism of Li-metal anodes is introduced.The advantages and strategies of carbon-based hosts to address the corresponding challenges are generalized.The unique function,existing limitation,and recent research progress of key carbon-based host materials for Li-metal anodes are reviewed.Finally,a conclusion and an outlook for future research of carbon-based hosts are presented.This review is dedicated to summarizing the advances of carbon-based materials hosts in recent years and providing a reference for the further development of carbonbased hosts for advanced Li-metal anodes.Xiaolin Yan Liang Lin Qiulin Chen Qingshui Xie Baihua Qu Laisen Wang Dong-Liang Peng 2021Carbon Energy2021,3,2:8

17Characterization and pilot scale test of a fluidized bed two-stage gasification process for the production of clean industrial fuel gas from low-rank coal显示文摘To utilize low rank coal efficiently,a fluidized bed two-stage(FBTS)gasification process,mainly consisting of a FB pyrolyzer and a transport FB(TFB)gasifier,has been proposed for the production of clean fuel gas.To verify the feasibility and technical features of this novel gasification technology,a pilot autothermal platform,with a treating capacity of 100 kg/h for coal,was designed and built up.By adopting a kind of lignite from Inner Mongolia,the running state and fuel gas quality were compared systematically under typical operational conditions.The results show that by keeping the reaction temperatures of pyrolyzer and gasifier at around 840C and 1000C,respectively,the corresponding tar content in fuel gas at the outlets of pyrolyzer and gasifier were 1127 mg/Nm3 and 365 mg/Nm3,reaching a high tar removal efficiency.Under the stable operation state,the volume fractions of CO,H2,CH4 and CO2 in fuel gas were 14.4%,8.3%,3.4%and 11.3%,respectively,and the corresponding higher heating value of fuel gas was about 1100 kcal/Nm3.Compared with the tar from pyrolyzer,the heavy oil fraction in tar from gasifier reduced significantly,while the light oil components increased sharply simultaneously,showing significant effect of catalytic reforming by hot char bed on tar removal.Xi Zeng Fang Wang Zhennan Han Yanlin Sun Yanbin Cui Guangwen Xu 2018Carbon Resources Conversion2018,1,1:8
18Review on DFT calculation of s-triazine-based carbon nitride显示文摘To improve the photocatalytic performance of pristine photocatalysts,element doping,construction of composites and fabrication of novel nanostructures are recognized as universal modification methods.These methods have been experimentally verified to be effective in manifold photocatalytic application over various photocatalysts.Density functional theory(DFT)calculation is a powerful and fundamental tool to pinpoint the intrinsic mechanism of the enhanced photocatalytic activity.And it holds the degree of precision ranging from atoms,molecules to unit cells.Herein,recent DFT calculation research progress of modified s-triazine-based graphitic carbon nitride(g-C3N4)systems as photocatalysts is summarized.To specify,we collected information of doping site,formation energy,geometric,and electronic properties.We also discussed the synergistic effect of work function,Fermi level and band edge position on the built-in electric field,transfer route of photogenerated charge carriers and photocatalytic mechanism(traditional typeⅡor direct Z-scheme heterostructure).Moreover,we analyzed the geometric configuration,band structure,and stability of g-C3N4 nanocluster,nanoribbon,and nanotube.Finally,future perspective in the further theoretical revelation of g-C3N4-based photocatalysts is proposed.Bicheng Zhu Bei Cheng Liuyang Zhang Jiaguo Yu 2019Carbon Energy2019,1,1:8
19Metal-organic framework-derived Fe/Cu-substituted Co nanoparticles embedded in CNTs-grafted carbon polyhedron for Zn-air batteries显示文摘Metal-organic frameworks(MOFs)and MOF-derived materials have attracted great attention as alternatives to noble-metal based electrocatalysts owing to their intriguing structure properties,especially for high efficiency and stable oxygen reduction reaction(ORR).Herein,we employed a one-pot reaction to make a multimetal(Fe,Co,Cu,and Zn)mixed zeolitic imidazolate framework(MM-ZIF)via adopting a simple in situ redox reaction.Further pyrolysis of the target MM-ZIF,a highly porous carbon polyhedron(FC-C@NC)grafted with abundant carbon nanotubes was obtained,in which ultrasmall Co nanoparticles with partial lattice sites substituted by Fe and Cu were embedded.The obtained FC-C@NC possessed large surface area,highly porous structure,widely-spread metal active sites,and conductive carbon frameworks,contributing to outstanding ORR activity and long-term stability.It displayed superior tolerance to methanol crossover and exceeded the commercial Pt/C catalyst and most previously reported non-noble-metal catalysts.Impressively,the as-produced FC-C@NC-based zinc-air battery afforded an open-circuit potential of 1.466 V,a large specific capacity of 659.5 mAh/g,and a high gravimetric energy density of 784.3 Wh/kgZn,significantly outperforming the Pt/C-based cathode.Kexin Zhang Yelong Zhang Qinghua Zhang Zibin Liang Lin Gu Wenhan Guo Bingjun Zhu Shaojun Guo Ruqiang Zou 2020Carbon Energy2020,2,2:7
20Comparative kinetics of coal and oil shale pyrolysis in a micro fluidized bed reaction analyzer显示文摘The characteristics and kinetics of coal and oil shale pyrolysis were comparatively studied by using a micro fluidized bed reaction analyzer(MFBRA).The isothermal differential model was first applied to calculate the kinetic parameters of activation energy and frequency factor according to the major gas components during pyrolysis.The results showed that the major gas components released from coal and oil shale under the isothermal condition had different initiating and ending time points,and the difference was more significant under the programmed heating conditions.The shrinking core model allowed better fitting relevance for the coal pyrolysis,while the three-dimension model was more suitable for oil shale pyrolysis,indicating that the gases from the pyrolysis process of coal and oil shale might go through different reaction paths.The activation energy of oil shale pyrolysis was 36.96 kJ·mol^(−1),larger than the value of pyrolysis of the two coals,which was 21.16 and 32.17 kJ·mol^(−1),respectively.The above results justified that the oil shale pyrolysis with high ash contents was somehow more difficult to take place in terms of higher activation energy and the MFBRA could be a useful tool to give some insight into the intrinsic kinetics and reaction mechanisms of coal and oil shale pyrolysis.Yuming Zhang Mengxuan Zhao Rongxuan Linghu Chengxiu Wang Shu Zhang 2019Carbon Resources Conversion2019,2,3:7
