| 1 | Interfacial compatibility issues in rechargeable solid-state lithium metal batteries:a review显示文摘Solid-state lithium metal batteries(SSLBs)contain various kinds of interfaces,among which the solid electrode|solid electrolyte(ED|SE)interface plays a decisive role in the battery's power density and cycling stability.However,it is still lack of comprehensive knowledge and understanding about various interfacial physical/chemical processes so far.Although tremendous efforts have been dedicated to investigate the origin of large interfacial resistance and sluggish charge(electron/ion)transfer process,many scientific and technological challenges still remain to be clarified.In this review,we detach and discuss the critical individual challenge,including charge transfer process,chemical and electrochemical instability,space charge layers,physical contact and mechanical instability.The fundamental concepts,individual effects on the charge transfer and potential solutions are summarized based on material's thermodynamics,electrode kinetics and mechanical effects.It is anticipated that future research should focus on quantitative analysis,modeling analysis and in-situ microstructure characterizations in order to obtain an efficient manipulation about the complex interfacial behaviors in all solid-state Li batteries. | Hongchun Wang Jianping Zhu Yu Su Zhengliang Gong Yong Yang | 2021 | Science China Chemistry2021，64，6： | 3 |
| 2 | The application of synchrotron X-ray techniques to the study ofrechargeable batteries显示文摘The increased use of rechargeable batteries in portable electronic devices and the continuous development of novel applications(e.g. transportation and large scale energy storage), have raised a strong demand for high performance batteries with increased energy density, cycle and calendar life, safety and lower costs. This triggers significant efforts to reveal the fundamental mechanism determining battery performance with the use of advanced analytical techniques. However, the inherently complex characteristics of battery systems make the mechanism analysis sophisticated and difficult. Synchrotron radiation is an advanced collimated light source with high intensity and tunable energies. It has particular advantages in electronic structure and geometric structure(both the short-range and long-range structure)analysis of materials on different length and time scales. In the past decades, synchrotron X-ray techniques have been widely used to understand the fundamental mechanism and guide the technological optimization of batteries. In particular, in situ and operando techniques with high spatial and temporal resolution, enable the nondestructive, real time dynamic investigation of the electrochemical reaction,and lead to significant deep insights into the battery operation mechanism.This review gives a brief introduction of the application of synchrotron X-ray techniques to the investigation of battery systems. The five widely implicated techniques, including X-ray diffraction(XRD), Pair Distribution Function(PDF), Hard and Soft X-ray absorption spectroscopy(XAS) and X-ray photoelectron spectroscopy(XPS) will be reviewed, with the emphasis on their in situ studies of battery systems during cycling. | Zhengliang Gong Yong Yang | 2018 | Journal of Energy Chemistry2018，27，6： | 3 |
| 3 | Efficient Two-Dimensional Extrapolation Technique of Scattering Problems Involving Dielectric Objects Using PMCHWT Formulation显示文摘An efficient extrapolation technique of Radar cross-section(RCS) combines with Poggio-MillerChang-Harrington-Wu-Tsai(PMCHWT) formulation is presented for the fast analysis by arbitrary shaped threedimensional homogeneous lossy dielectric objects. The PMCHWT formulation obtained in a well-known manner is discretized to matrix equations using the Method of moments(Mo M). For the RCS is highly angular dependent as well as frequency, a novel rational function scheme is extended to the induced currents associated with PMCHWT,which can provide fast and accurate radar cross-section computation in both the frequency domain and spatial domain simultaneously. Numerical results are presented for two canonical dielectric scatterers. | LV Zhengliang GONG Shuxi ZHANG Pengfei HONG Tao | 2014 | Chinese Journal of Electronics2014，23，3： | 2 |

| 19 | Study of rapid face modeling technology based on Kinect显示文摘This paper improves the algorithm of point cloud filtering and registration in 3D modeling,aiming for smaller sampling error and shorter processing time of point cloud data.Based on collaborative sampling among several Kinect devices,we analyze the deficiency of current filtering algorithm,and use a novel method of point cloud filtering.Meanwhile,we use Fast Point Feature Histogram(FPFH)algorithm for feature extraction and point cloud registration.Compared with the aligning process using Point Feature Histograms(PFH),it only takes 9min when the number of points is about 500,000,shortening the aligning time by 47.1%.To measure the accuracy of the registration,we propose an algorithm which calculates the average distance of the corresponding coincident parts of two point clouds,and we improve the accuracy to an average distance of 0.7mm.In the surface reconstruction section,we adopt Ball Pivoting algorithm for surface reconstruction,obtaining image with higher accuracy in a shorter time. | Shan Liu Guanghong Gong Luhao Xiao Mengyuan Sun Zhengliang Zhu | 2018 | International Journal of Modeling, Simulation, and Scientific Computing2018，9，1： | 0 |
| 20 | Reinforced cathode-garnet interface for high-capacity all-solid-state batteries显示文摘Garnet-type solid-state electrolytes(SSEs)are particularly attractive in the construction of all-solid-state lithium(Li)batteries due to their high ionic conductivity,wide electrochemical window and remarkable(electro)chemical stability.However,the intractable issues of poor cathode/garnet interface and general low cathode loading hinder their practical application.Herein,we demonstrate the construction of a reinforced cathode/garnet interface by spark plasma sintering,via co-sintering Li_(6.5)La_(3)Zr_(1.5)Ta_(0.5)O_(12)(LLZTO)electrolyte powder and LiCoO_(2)/LLZTO composite cathode powder directly into a dense dual-layer with 5 wt%Li_(3)BO_(3)as sintering additive.The bulk composite cathode with LiCoO_(2)/LLZTO cross-linked structure is firmly welded to the LLZTO layer,which optimizes both Li-ion and electron transport.Therefore,the one-step integrated sintering process implements an ultra-low cathode/garnet interfacial resistance of 3.9Ωcm^(2)(100◦C)and a high cathode loading up to 2.02 mAh cm^(−2).Moreover,the Li_(3)BO_(3)reinforced LiCoO_(2)/LLZTO interface also effectively mitigates the strain/stress of LiCoO_(2),which facilitates the achieving of superior cycling stability.The bulk-type Li|LLZTO|LiCoO_(2)-LLZTO full cell with areal capacity of 0.73 mAh cm^(−2)delivers capacity retention of 81.7%after 50 cycles at 100μA cm^(−2).Furthermore,we reveal that non-uniform Li plating/stripping leads to the formation of gaps and finally results in the separation of Li and LLZTO electrolyte during long-term cycling,which becomes the dominant capacity decay mechanism in high-capacity full cells.This work provides insight into the degradation of Li/SSE interface and a strategy to radically improve the electrochemical performance of garnet-based all-solid-state Li batteries. | Chenxi Zheng Shijun Tang Fangmei Wen Jinxue Peng Wu Yang Zhongwei Lv Yongmin Wu Weiping Tang Zhengliang Gong Yong Yang | 2022 | Materials Futures2022，1，4： | 0 |
