| 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 | Self-healing alginate-carboxymethyl chitosan porous scaffold as an effective binder for silicon anodes in lithium-ion batteries显示文摘Polymer binder plays a pivotal role in electrochemical performance of high-capacity silicon(Si)anode that usually suffers from severe capacity fading due to enormous substantial volume change of Si during cycling.In an effort to find efficient polymer binder that could mitigate such capacity fading,alginate-carboxymethyl chitosan(Alg-C-chitosan)composite polymer was investigated as a low-cost watersoluble binder for silicon anodes in lithium-ion batteries.The electrostatic interaction between carboxylate(-COO-)of Alg and protonated amines(-NH3+)of C-chitosan forms a selfhealing porous scaffold structure.Synergistic effect on the enhanced porous scaffold structure and self-healing electrostatic interaction of Alg-C-chitosan binder effectively can tolerate the tremendous volume change of Si and maintain an integrated electrode structure during cycling process.The Si nanopowder electrodes with Alg-C-chitosan composite binder exhibit an excellent cycling stability,with a capacity of750 mAh·g-1 remaining after 100 th cycling.In addition,an extraordinary areal capacity of 3.76 mAh·cm-2 is achieved for Si-based anodes with Alg-C-chitosan binder. | Zhao-Hui Wu Juan-Yu Yang Bing Yu Bi-Meng Shi Chun-Rong Zhao Zhang-Long Yu | 2019 | Rare Metals2019，38，9： | 22 |
| 3 | A scalable synthesis of silicon nanoparticles as high-performance anode material for lithium-ion batteries显示文摘In this work, a scalable and cost-effective method including mechanical milling, centrifugation and spray drying was developed to fabricate Si nanoparticles.The synthesized Si nanoparticles show an average size of 62 nm and exhibit a narrow particle size distribution. The influence of particle sizes on electrochemical performance of Si-based electrode was investigated, and it is found that as the particle size decreases in the studied range, the Si particles show a lower specific capacity and a higher irreversible capacity loss(ICL). Furthermore, an oxide layer with thickness of ~3 nm was detected on the surface of the as-received Si nanoparticles, and this layer can be effectively removed by hydrofluoric acid(HF) etching,resulting in much improved electrochemical performance over the as-received samples. | Jin Li Juan-Yu Yang Jian-Tao Wang Shi-Gang Lu | 2019 | Rare Metals2019，38，3： | 20 |
| 4 | Nitrogen doped porous carbon as excellent dual anodes for Li-and Na-ion batteries显示文摘Biomass-derived carbon materials have obtained great attention due to their sustainability,easy availability,low cost and environmentally benign.In this work,bamboo leaves derived nitrogen doped hierarchically porous carbon have been efficiently synthesized via an annealing approach,followed by an etching process in HF solution.Electrochemical measurements demonstrate that the unique porous structure,together with the inherent high nitrogen content,endow the as-derived carbon with excellent lithium/sodium storage performance.The porous carbon annealed at 700℃presents outstanding rate capability and remarkable long-term stability as anodes for both lithium-ion batteries and sodium-ion batteries.The optimized carbon delivers a high discharge capacity of 450 mAh/g after 500 cycles at the current density of 0.2 A/g for LIBs,and a discharge capacity of 180 mAh/g after 300 cycles at the current density of 0.1 A/g for SIBs. | Zhanheng Yan Qin-Wen Yang Qinghong Wang Jianmin Ma | 2020 | Chinese Chemical Letters2020，31，2： | 20 |
| 5 | Encapsulating segment-like antimony nanorod in hollow carbon tube as long-lifespan,high-rate anodes for rechargeable K-ion batteries显示文摘K-ion battery (KIB) is a new-type energy storage device that possesses potential advantages of low-cost and abundant resource of potassium.To develop advanced electrode materials for accommodating the large size and high activity of potassium ion is of great interests.Herein,a segment-like antimony (Sb) nanorod encapsulated in hollow carbon tube electrode material (Sb@HCT) was prepared.Beneficial from the virtue of abundant nitrogen doping in carbon tube,one-dimensional and hollow structure advantages,Sb@HCT exhibits excellent potassium storage properties:in the case of potassium bis(fluorosulfonyl)imide (KFSI) electrolyte,Sb@HCT displays a reversible capacity of up to 453.4 mAh·g^-1 at a current density of 0.5 A·g^-1 and good rate performance (a capacity of 211.5 mAh·g^-1 could be achieved at an ultrahigh rate of 5 A·g^-1).Additionally,Sb@HCT demonstrates excellent long-cycle stability at a current density of 2 A·g^-1 over 120 cycles.Meanwhile,electrolyte optimization is an effective strategy for greatly improving electrochemical performance.Through ex-situ characterizations,we disclosed the potassiation of Sb anode is quite reversible and undergoes multistep processes,combining solid solution reaction and two-phase reaction. | Wen Luo Feng Li Weiran Zhang Kang Han Jean-Jacques Gaumet Hans-Eckhardt Schaefer Liqiang Mai | 2019 | Nano Research2019，12，5： | 18 |

| 7 | Recent progress on lithium-ion batteries with high electrochemical performance显示文摘Lithium-ion batteries(LIBs) have been widely used in many fields such as portable electronics and electric vehicles since their successful commercialization in the 1990 s. However, the electrochemical performance of current commercial LIBs still needs to be further improved to meet the continuously increasing demands for energy storage applications. Recently, tremendous research efforts have been made in developing next-generation LIBs with enhanced electrochemical performance. In this review, we mainly focus on the recent progress of LIBs with high electrochemical performance from four aspects, including cathode materials, anode materials, electrolyte, and separators. We discuss not only the commercial electrode materials(LiCoO_2,LiFePO_4, LiMn_2O_4, LiNi_xMn_yCo_zO_2, LiNi_xCo_yAl_zO_2, and graphite) but also other promising next-generation materials such as Li-, Mn-rich layered oxides, organic cathode materials, Si, and Li metal. For each type of materials, we highlight their problems and corresponding strategies to enhance their electrochemical performance. Nowadays, one of the key challenges to construct high-performance LIBs is how to develop cathode materials with high capacity and working voltage. This review provides an overview and future perspectives to develop next-generation LIBs with high electrochemical performance. | Yong Lu Qiu Zhang Jun Chen | 2019 | Science China Chemistry2019，62，5： | 16 |
| 8 | Hard carbon derived from cellulose as anode for sodium ion batteries:Dependence of electrochemical properties on structure显示文摘Cellulose, the most abundant organic polymer on Earth, is a sustainable source of carbon to use as a negative electrode for sodium ion batteries. Here, hard carbons(HC) prepared by cellulose pyrolysis were investigated with varying pyrolysis temperature from 700 °C to 1600 °C. Characterisation methods such as Small Angle X-ray Scattering(SAXS) measurements and N_2 adsorption were performed to analyse porosity differences between the samples. The graphene sheet arrangements were observed by transmission electron microscopy(TEM): an ordering of the graphene sheets is observed at temperatures above 1150 °C and small crystalline domains appear over 1400 °C. As the graphene sheets start to align, the BET surface area decreases and the micropore size increases. To correlate hard carbon structures and electrochemical performances, different tests in Na//HC cells with 1 M NaPF_6 ethylene carbonate/dimethyl carbonate(EC/DMC) were performed. Samples pyrolysed from 1300 °C to 1600 °C showed a 300 m Ah/g reversible capacity at C/10 rate(where C = 372 mA/g) with an excellent stability in cycling and a very good initial Coulombic efficiency of up to 84%. Furthermore, hard carbons showed an excellent rate capability where sodium extraction rate varies from C/10 to 5C. At 5C more than 80% of reversible capacity remains stable for hard carbons synthesized from 1000 °C to 1600 °C. | V.Simone A.Boulineau A.de Geyer D.Rouchon L.Simonin S.Martinet | 2016 | Journal of Energy Chemistry2016，25，5： | 16 |
| 9 | Lithium metal anodes: Present and future显示文摘Commercial lithium-ion(Li-ion)batteries based on graphite anodes are meeting their bottlenecks that are limited energy densities.In order to satisfy the large market demands of smaller and lighter rechargeable batteries,high-capacity metallic Li replacing low-specific-capacity graphite enables the higher energy density in next-generation rechargeable Li metal batteries(LMBs).However,Li metal anode has been suffering from dendritic problems,interfacial side reactions,volume change and low Coulombic efficiency.Therefore,performance enhancements of Li metal anodes are rather important to realize the high energy density characteristic of metallic Li.In this review,the annoying Li dendrite growth,unstable reaction interface and practical application issues of Li metal anodes are summarized and detailedly discussed to understand the current challenges concerning Li metal anodes.For overcoming such remaining challenges,the corresponding strategies and recent advances are covered and categorized.Finally,we discuss future opportunities and perspectives for developing high-performance Li metal anodes. | Renheng Wang Weisheng Cui Fulu Chu Feixiang Wu | 2020 | Journal of Energy Chemistry2020，29，9： | 15 |
| 10 | Porous LiF layer fabricated by a facile chemical method toward dendrite-free lithium metal anode显示文摘Lithium metal is supposed to be critical material for constructing next-generation batteries due to extremely high capacity and ultralow redox potential. However, the perplexing issue of lithium dendrite growth impedes the commercial application. The initial nucleation and low Li ions diffusion rate in the electrolyte/electrode interface dominate the deposition behavior. Therefore, a uniform and flexible interface is urgently needed. Here, a facile method is proposed to prepare a thin and porous LiF-rich layer (TPL) by the in-situ reaction of small amount of ammonium hydrogen difluoride (NH4HF2) and Li metal. The deposition morphology on Li metal anode with LiF layer is significantly flat and homogeneous owning to low lateral diffusion barrier on LiF crystals and the porous structure of TPL film. Additionally, the symmetrical cells made with such TPL Li anodes show significantly stable cycling over 100 cycles at high current density of 6 mA/cm^2. The TPL Li|LiFePO4 full cells keep over 99% capacity retention after 100 cycles at 2.0 C. This approach serves as a facile and controllable way of adjusting the protective layer on Li metal. | Yanxia Yuan Feng Wu Guanghai Chen Ying Bai Chuan Wu | 2019 | Journal of Energy Chemistry2019，28，10： | 14 |
| 11 | Designing solid-state interfaces on lithium-metal anodes: a review显示文摘Li-metal anodes are one of the most promising energy storage systems that can considerably exceed the current technology to meet the ever-increasing demand of power applications. The apparent cycling performances and dendrite challenges of Li-metal anodes are highly influenced by the interface layer on the Li-metal anode because the intrinsic high reactivity of metallic Li results in an inevitable solid-state interface layer between the Li-metal and electrolytes. In this review, we summarize the recent progress on the interfacial chemistry regarding the interactions between electrolytes and ion migration through dynamic interfaces. The critical factors that affect the interface formation for constructing a stable interface with a low resistance are reviewed. Moreover, we review emerging strategies for rationally designing multiple-structured solid-state electrolytes and their interfaces, including the interfacial properties within hybrid electrolytes and the solid electrolyte/electrode interface. Finally, we present scientific issues and perspectives associated with Li-metal anode interfaces toward a practical Li-metal battery. | Chen-Zi Zhao Hui Duan Jia-Qi Huang Juan Zhang Qiang Zhang Yu-Guo Guo Li-Jun Wan | 2019 | Science China Chemistry2019，62，10： | 14 |

| 16 | Boosting lithium storage performance of Si nanoparticles via thin carbon and nitrogen/phosphorus co-doped two-dimensional carbon sheet dual encapsulation显示文摘Silicon(Si)is a promising anode candidate for next-generation lithium-ion batteries(LIBs),but it suffers from poor electronic conductivity and dramatic volume variation during cycling,which poses a critical challenge for stable battery operation.To mitigate these issues simultaneously,we propose a'double carbon synergistic encapsulation'strategy,namely thin carbon shell and nitrogen/phosphorus co-doped two-dimensional(2D)carbon sheet dual encapsulate Si nanoparticles(denoted as 2D NPC/C@Si).This double carbon structure can serve as a conductive medium and buffer matrix to accommodate the volume expansion of Si nanoparticles and enable fast electron/ion transport,which promotes the formation of a stable solid electrolyte interphase film during cycling.Through structural advantages,the resulting 2 D NPC/C@Si electrode demonstrates a high reversible capacity of592 mAh·g^(-1) at 0.2 A·g^(-1) with 90.5%excellent capacity retention after 100 cycles,outstanding rate capability(148 mAh·g^(-1) at 8 A·g^(-1)),and superior long-term cycling stability(326 mAh·g^(-1) at 1 A·g^(-1) for 500 cycles,86%capacity retention).Our findings elucidate the development of high-performance Si@C composite anodes for advanced LTBs. | Cheng-Zhi Ke Fang Liu Zhi-Ming Zheng He-He Zhang Meng-Ting Cai Miao Li Qi-Zhang Yan Hui-Xin Chen Qiao-Bao Zhang | 2021 | Rare Metals2021，40，6： | 11 |

| 18 | Recent progress on the recycling technology of Li-ion batteries显示文摘Lithium-ion batteries(LIBs)have been widely applied in portable electronic devices and electric vehicles.With the booming of the respective markets,a huge quantity of spent LIBs that typically use either LiFePO_(4) or Li N_(x)Co_(y)Mn_(z)O_(2) cathode materials will be produced in the very near future,imposing significant pressure for the development of suitable disposal/recycling technologies,in terms of both environmental protection and resource reclaiming.In this review,we firstly do a comprehensive summary of the-state-of-art technologies to recycle Li N_(x)Co_(y)Mn_(z)O_(2) and LiFePO_(4)-based LIBs,in the aspects of pretreatment,hydrometallurgical recycling,and direct regeneration of the cathode materials.This closed-loop strategy for cycling cathode materials has been regarded as an ideal approach considering its economic benefit and environmental friendliness.Afterward,as for the exhausted anode materials,we focus on the utilization of exhausted anode materials to obtain other functional materials,such as graphene.Finally,the existing challenges in recycling the LiFePO_(4) and Li N_(x)Co_(y)Mn_(z)O_(2) cathodes and graphite anodes for industrial-scale application are discussed in detail;and the possible strategies for these issues are proposed.We expect this review can provide a roadmap towards better technologies for recycling LIBs,shed light on the future development of novel battery recycling technologies to promote the environmental benignity and economic viability of the battery industry and pave way for the large-scale application of LIBs in industrial fields in the near future. | Yuqing Wang Ning An Lei Wen Lei Wang Xiaotong Jiang Feng Hou Yuxin Yin Ji Liang | 2021 | Journal of Energy Chemistry2021，30，4： | 10 |
| 19 | Growth of SnO_2 Nanoflowers on N-doped Carbon Nanofibers as Anode for Li-and Na-ion Batteries显示文摘It is urgent to solve the problems of the dramatic volume expansion and pulverization of SnO_2 anodes during cycling process in battery systems. To address this issue, we design a hybrid structure of N-doped carbon fibers@SnO_2 nanoflowers(NC@SnO_2) to overcome it in this work. The hybrid NC@SnO_2 is synthesized through the hydrothermal growth of SnO_2 nanoflowers on the surface of N-doped carbon fibers obtained by electrospinning. The NC is introduced not only to provide a support framework in guiding the growth of the SnO_2 nanoflowers and prevent the flower-like structures from agglomeration, but also serve as a conductive network to accelerate electronic transmission along one-dimensional structure effectively. When the hybrid NC@SnO_2 was served as anode, it exhibits a high discharge capacity of 750 Ah g^(-1) at 1 A g^(-1) after 100 cycles in Li-ion battery and 270 mAh g^(-1) at 100 mA g^(-1) for 100 cycles in Na-ion battery, respectively. | Jiaojiao Liang Chaochun Yuan Huanhuan Li Kai Fan Zengxi Wei Hanqi Sun Jianmin Ma | 2018 | Nano-Micro Letters2018，10，2： | 10 |
| 20 | Recent progress in Ti-based nanocomposite anodes for lithium ion batteries显示文摘Studying on the anode materials with high energy densities for next-generation lithium-ion batteries(LIBs) is the key for the wide application for electrochemical energy storage devices.Ti-based compounds as promising anode materials are known for their outstanding high-rate capacity and cycling stability as well as improved safety over graphite.

Here, we present an overview of the recent development of Ti-based anode materials in LIBs, and special emphasis is placed on capacity enhancement by rational design of hybrid nanocomposites with conversion-/alloying-type anodes. This review is expected to provide a guidance for designing novel Ti-based materials for energy storage and conversion. | Shitong WANG Yong YANG Yanhao DONG Zhongtai ZHANG Zilong TANG | 2019 | Journal of Advanced Ceramics2019，8，1： | 10 |
