| 1 | Mechanism of intercalation and deintercalation of lithium ions in graphene nanosheets显示文摘Graphene nanosheets (GNSs) were synthesized by reducing exfoliated graphite oxides. Their structure, surface morphology and lithium storage mechanism were characterized and investigated systematically using X-ray diffraction, atomic force microscopy, scanning electron microscopy, charge-discharge tests, cyclic voltammetry and electrochemical impedance spectroscopy. It was found that the GNSs, which were obtained via chemical synthesis, were primarily less than 10 graphene layers. The GNS electrodes, which were fabricated from the reduced GNSs, exhibited an enhanced reversible lithium storage capacity and good cyclic stability when serving as anodes in lithium-ion batteries. Also, the first-cycle irreversible capacities of the system were relatively high, because of the formation of a solid electrolyte interphase film on the surface of the GNS electrode and the spontaneous stacking of GNSs during the first lithiation. The electrochemical impedance spectroscopy results suggest that the solid electrolyte interphase film on the GNS electrode during first lithiation were primarily formed at potentials between 0.95 and 0.7 V. Also, the symmetry factor of the charge transfer was measured to be 0.446. | TIAN LeiLei ZHUANG QuanChao LI Jia SHI YueLi CHEN JianPeng LU Feng SUN ShiGang | 2011 | Chinese Science Bulletin2011，56，30： | 11 |
| 2 | Effect of electrolysis voltage on electrochemical reduction of titanium oxide to titanium in molten calcium chloride显示文摘The electrochemical reduction of solid TiO2 directly to solid metal is a promising alternative to the current Kroll process. The present work is aimed at studying the effect of electrolysis voltage on the rate of electrochemical reduction. The products of electrochemical reduction of TiO2 and Ti2O were examined using the scanning electron microscopy (SEM) and X-ray diffraction (XRD) techniques. The results show that Ti2O was reduced to low valent titanium oxide at 1.5-1.7 V, which was the result of ionization of oxygen. TiO2 and Ti2O were reduced to titanium metal at 2.1-3.1 V, which was the co-action of ionization of oxygen and calciothermic reduction. The oxygen content decreased rapidly with voltage increas-ing from 2.1 to 2.6 V, while it changed little from 2.6 to 3.1 V. The optimized cell voltage was 2.6-3.1 V. | LIU Meifeng LU Shigang KAN Surong LI Guoxun | 2007 | Rare Metals2007，26，6： | 7 |

| 4 | 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 |
| 5 | Understanding divergent domestication traits from the whole-genome sequencing of swamp-and river-buffalo populations显示文摘Domesticated buffaloes have been integral to rice-paddy agro-ecosystems formillennia,yet relatively little is known about the buffalo genomics.Here,we sequenced and assembled reference genomes for both swamp and river buffaloes and we re-sequenced 230 individuals(132 swamp buffaloes and 98 river buffaloes)sampled from across Asia and Europe.Beyond the many actionable insights that our study revealed about the domestication,basic physiology and breeding of buffalo,we made the striking discovery that the divergent domestication traits between swamp and river buffaloes can be explained with recent selections of genes on social behavior,digestion metabolism,strengths and milk production. | Xier Luo Yu Zhou Bing Zhang Yi Zhang Xiaobo Wang Tong Feng Zhipeng Li Kuiqing Cui Zhiqiang Wang Chan Luo Hui Li Yanfei Deng Fenghua Lu Jianlin Han Yongwang Miao Huaming Mao Xiaoyan Yi Cheng Ai Shigang Wu Alun Li Zhichao Wu Zijun Zhuo Do Da Giang Bikash Mitra Mohammad Farhad Vahidi Shahid Mansoor Sahar Ahmed Al-Bayatti Eka Meutia Sari Neena Amatya Gorkhali Sigit Prastowo Laiba Shafique Guoyou Ye Qian Qian Baoshan Chen Deshun Shi Jue Ruan Qingyou Liu | 2020 | National Science Review2020，7，3： | 3 |

| 7 | Long-lasting impairments in rodent oxygen-induced retinopathy measured by retinal vessel density and visual function显示文摘In mild or moderate retinopathy of prematurity(ROP), retinal vessels undergo obliteration, proliferation, and regression. Despite complete regression of vessel abnormalities, a variety of visual impairments have been reported. Rodent oxygen-induced retinopathy(OIR) is widely used as a model to study ROP. However, the long-term changes of OIR model remain unclear. The aim of this study is to examine long term changes of retinal vessel and visual function in a rodent OIR model resembling human mild or moderate ROP. In this study, after subjecting the animals to 80% oxygen(O_2) for 5–7 d, the retinal vessel density at postnatal day 12(P12) was approximately 30% lower than that in the age-matched control, but this difference was not significant between the groups. Vessel abnormalities, such as vessel tortuosity, neovascular tufts, and the number of vessels protruding into the vitreous, peaked between P17 and P20. Despite the regression of many abnormalities, vessel density in the OIR group was 36% and 32% lower than that in the control animals at 6 weeks and 4 months, respectively. The visual acuity and contrast sensitivity were impaired in the OIR group when measured at 2, 3 and 4 months. Therefore, the rodent OIR model exhibited long-lasting reduction in retinal vessel density and visual impairments, similar to those observed in mild or moderate human ROP. This study suggests that the rodent OIR model can be used to explore possible interventions for mild and moderate human ROP. | Xu Wang Ke Shen Fang Lu Shigang He | 2019 | Science China(Life Sciences)2019，62，5： | 2 |
| 8 | Failure analysis of pouch-type Li–O2 batteries with superior energy density显示文摘Li–O2 batteries have attracted significant interest in the past decade owing to their superior high specific energy density in contrast to conventional lithium ion batteries.An 8.7-Ah Li–O2 pouch cell with768.5 Wh kg^-1 was fabricated and characterized in this investigation and the factors that influenced the electrochemical performance of the Li–O2 pouch cell were studied.In contrast to coin/Swagelok-type Li–O2 cells,it was demonstrated that the high-loading air electrode,pulverization of the Li anode,and the large-scale inhomogeneity of the large pouch cell are the major reasons for the failure of Li–O2 batteries with Ah capacities.In addition,safety tests of large Li–O2 pouch cells were conducted for the first time,including nail penetration,crushing,and thermal stability.It was indicated that a self-limiting mechanism is a key safety feature of these batteries,even when shorted.In this study,Li–O2 batteries were investigated in a new size and capacity-scale,which may provide useful insight into the development of practical pouch-type Li–O2 batteries. | Shangqian Zhao Li Zhang Gangning Zhang Haobo Sun Juanyu Yang Shigang Lu | 2020 | Journal of Energy Chemistry2020，29，6： | 2 |
| 9 | LiFePO_4/C via fluoride doping显示文摘Non-stoichiometric compound fluoride-doped LiFePO4/C cathode materials were synthesized via solid-state reaction using MgF2 and AlF3 as dopant. The fluoride-doped LiFePO4/C samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and electrochemical testing. The results show that the materials are well crystallized and fluoride doping cannot change the space structure of LiFePO4. Slight amounts of Fe2O3 with no fluoride impurity were detected. Charge-discharge curves show that fluoride-doped samples have higher capacity at low rates compared with undoped LiFePO4/C. AlF3-doped samples have highest capacity at high discharge current. Both doped samples have larger polarization voltage than undoped samples. All samples exhibit good cycle stability. | Gu Yuan Zhang Xiangjun Lu Shigang Zhao Ting Jiang Danping Yang Rong Wu Aide | 2012 | Rare Metals2012，31，6： | 2 |

| 15 | Review of the electrochemical performance and interfacial issues of high-nickel layered cathodes in inorganic all-solid-state batteries显示文摘All-solid-state batteries potentially exhibit high specific energy and high safety,which is one of the development directions for nextgeneration lithium-ion batteries.The compatibility of all-solid composite electrodes with high-nickel layered cathodes and inorganic solid electrolytes is one of the important problems to be solved.In addition,the interface and mechanical problems of high-nickel layered cathodes and inorganic solid electrolyte composite electrodes have not been thoroughly addressed.In this paper,the possible interface and mechanical problems in the preparation of high-nickel layered cathodes and inorganic solid electrolytes and their interface reaction during charge–discharge and cycling are reviewed.The mechanical contact problems from phenomena to internal causes are also analyzed.Uniform contact between the high-nickel cathode and solid electrolyte in space and the ionic conductivity of the solid electrolyte are the prerequisites for the good performance of a high-nickel layered cathode.The interface reaction and contact loss between the high-nickel layered cathode and solid electrolyte in the composite electrode directly affect the passage of ions and electrons into the active material.The buffer layer constructed on the high-nickel cathode surface can prevent direct contact between the active material and electrolyte and slow down their interface reaction.An appropriate protective layer can also slow down the interface contact loss by reducing the volume change of the high-nickel layered cathode during charge and discharge.Finally,the following recommendations are put forward to realize the development vision of high-nickel layered cathodes:(1)develop electrochemical systems for high-nickel layered cathodes and inorganic solid electrolytes;(2)elucidate the basic science of interface and electrode processes between high-nickel layered cathodes and inorganic solid electrolytes,clarify the mechanisms of the interfacial chemical and electrochemical reactions between the two materials,and address the intrinsic safety issues;(3)strengthen the development of research and engineering technologies and their preparation methods for composite electrodes with high-nickel layered cathodes and solid electrolytes and promote the industrialization of all-solid-state batteries. | Jing Wang Shangqian Zhao Ling Tang Fujuan Han Yi Zhang Yimian Xia Lijun Wang Shigang Lu | 2022 | International Journal of Minerals,Metallurgy and Materials2022，29，5： | 1 |

| 19 | A novel 3D geometrical reconstruction method for aluminum foams and FEM modeling of the material response显示文摘A novel method for modeling cellular materials is proposed based on MATLAB image processing and synchrotron X-ray computed tomography scanning to obtain an accurate calculation result of aluminum foam based on finite element model. The maximum entropy algorithm is employed to obtain the binarization image, and the median filtering algorithm is used to reduce the noise after binarization. The external contour and internal pores boundary is extracted by the 'edge' function in MATLAB, and the geometrical model is reconstructed. A two-step mesh algorithm is adopted to mesh the reconstructed geometrical model.Accordingly, the finite element model of aluminum foam is established by the proposed method based on reconstruction geometrical model. The compression behavior of aluminum foam is obtained at 25℃, 100℃, 200℃ by ABAQUS, and good agreements with experiments are achieved by applying the present reconstruction algorithm and modeling method. | Xiaolei Zhu Shigang Ai Xiaofeng Lu Lingxue Zhu Bin Liu | 2014 | Theoretical & Applied Mechanics Letters2014，4，2： | 0 |
| 20 | Fundamental Understanding of Hydrogen Evolution Reaction on Zinc Anode Surface:A First‑Principles Study显示文摘Hydrogen evolution reaction(HER)has become a key factor affecting the cycling stability of aqueous Zn-ion batteries,while the corresponding fundamental issues involving HER are still unclear.Herein,the reaction mechanisms of HER on various crystalline surfaces have been investigated by first-principle calculations based on density functional theory.It is found that the Volmer step is the ratelimiting step of HER on the Zn(002)and(100)surfaces,while,the reaction rates of HER on the Zn(101),(102)and(103)surfaces are determined by the Tafel step.Moreover,the correlation between HER activity and the generalized coordination number(CN)of Zn at the surfaces has been revealed.The relatively weaker HER activity on Zn(002)surface can be attributed to the higher CN of surface Zn atom.The atomically uneven Zn(002)surface shows significantly higher HER activity than the flat Zn(002)surface as the CN of the surface Zn atom is lowered.The CN of surface Zn atom is proposed as a key descriptor of HER activity.Tuning the CN of surface Zn atom would be a vital strategy to inhibit HER on the Zn anode surface based on the presented theoretical studies.Furthermore,this work provides a theoretical basis for the in-depth understanding of HER on the Zn surface. | Xiaoyu Liu Yiming Guo Fanghua Ning* Yuyu Liu Siqi Shi Qian Li Jiujun Zhang Shigang Lu Jin Yi | 2024 | Nano-Micro Letters2024，16，6： | 0 |
