1Interface issues of lithium metal anode for high-energy batteries: Challenges, strategies, and perspectives显示文摘Lithium(Li)metal is considered as one of the most promising anode materials for next-generation high-energy-density storage systems.However,the practical application of Li metal anode is hindered by interfacial instability and air instability due to the highly reactivity of Li metal.Unstable interface in Li metal batteries(LMBs)directly dictates Li dendrite growth,“dead Li”and low Coulombic efficiency,resulting in inferior electrochemical performance of LMBs and even safety issues.In addition,its sensitivity to ambient air leads to the severe corrosion of Li metal anode,high requirements of production and storage,and increased manufacturing cost.Plenty of efforts in recent years have overcome many bottlenecks in these fields and hastened the practical applications of high-energy-density LMBs.In this review,we focus on emerging methods of these two aspects to fulfill a stable and low cost electrode.In this perspective,design artificial solid electrolyte interphase(SEI)layers,construct three-dimensional conductive current collectors,optimize electrolytes,employ solid-state electrolytes,and modify separators are summarized to be propitious to ameliorate interfacial stability.Meanwhile,ex situ/in situ formed protective layers are highlighted in favor of heightening air stability.Finally,several possible directions for the future research on advanced Li metal anode are addressed.Yiyao Han Bo Liu Zhen Xiao Wenkui Zhang Xiuli Wang Guoxiang Pan Yang Xia Xinhui Xia Jiangping Tu 2021InfoMat2021,3,2:11
2Revisiting 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 2018Energy & Environmental Materials2018,1,4:9
3Cultivation Ages Effect on Soil Physicochemical Properties and Heavy Metal Accumulation in Greenhouse Soils显示文摘The intensive management practices in greenhouse production may alter the soil physicochemical properties and contribute to the accumulation of heavy metals(HMs). To determine the HM concentrations in vegetable soil in relation to soil physicochemical properties and cultivation age, we conducted a soil survey for typical greenhouse soils in Shouguang, China. The results indicated that Cd is a major HM pollutant in the tested soils, as the only HM element exceeding the allowed limit for vegetable soil. The surveyed data was analyzed with regression analysis, correlation analysis and canonical correspondence analysis(CCA). A positive correlation is observed between HM pollution level and cultivation age. CCA results suggest that the HM pollution level and distribution in soil are significantly affected by soil physicochemical properties, which was a function of years of cultivation as revealed by regression analysis. In summary, cultivation age is an important factor to affect soil physicochemical properties(organic matter and inorganic nutrients) as well as HM contamination.WANG Jun MI Wenkui SONG Peipei XIE Hui ZHU Lusheng WANG Jinhua 2018Chinese Geographical Science2018,28,4:5
4Torque Distribution of Electric Vehicle with Four In-Wheel Motors Based on Road Adhesion Margin显示文摘With the worsening of energy crisis and environmental pollution,electric vehicles with four in?wheel motors have been paid more and more attention. The main research subject is how to reasonably distribute the driving torque of each wheel. Considering the longitudinal motion,lateral motion,yaw movement and rotation of the four wheels,the tire model and the seven DOF dynamic model of the vehicle are established in this paper. Then,the torque distribution method is proposed based on road adhesion margin,which can be divided into anti ? slip control layer and torque distribution layer. The anti?slip control layer is built based on sliding mode variable structure control,whose main function is to avoid the excessive slip of wheels caused by road conditions. The torque distribution layer is responsible for selecting the torque distribution method based on road adhesion margin. The simulation results show that the proposed torque distribution method can ensure the vehicle quickly adapt to current road adhesion conditions,and improve the handling stability and dynamic performance of the vehicle in the driving process.WANG Chunyan LI Wenkui ZHAO Wanzhong DUAN Tingting 2019Transactions of Nanjing University of Aeronautics and Astronautics2019,36,1:3
5In-situ construction of a Mg-modified interface to guide uniform lithium deposition for stable all-solid-state batteries显示文摘Uniform lithium(Li)deposition in all-solid-state Li metal batteries is greatly influenced by the anode/electrolyte interface.Herein,a Mg-modified interface was constructed via the simple in-situ electrochemical reduction of Mg^(2+)from Mg(TFSI)_(2) in polyethylene oxide(PEO)and a Li bis(trifluoromethane)sulfoni mide(Li TFSI)formulae.As confirmed by cryogenic transmission electron microscopy,the anode/electrolyte interface exhibited hybrids consisting of crystalline Mg,Li_(2)O,and Li dots embedded in an amorphous polymer electrolyte.The crystalline Mg dots guided the uniform Li nucleation and growth,inducing a smoother anode/electrolyte interface compared with the pristine electrolyte.With 1 wt%Mg(TFSI)_(2) in the PEO-Li TFSI electrolyte,the Mg-modified electrolyte enabled the Li/Li symmetric cells with cycling performance of over 1700 and 1400 h at current densities of 0.1 and 0.2 m A cm^(-2),respectively.Moreover,the full LFP/Li cells using the novel Mg-modified electrolyte delivered a cycling lifespan of over 450 cycles with negligible capacity loss.Tiefeng Liu Jiale Zheng Hualiang Hu Ouwei Sheng Zhijin Ju Gongxun Lu Yujing Liu Jianwei Nai Yao Wang Wenkui Zhang Xinyong Tao 2021Journal of Energy Chemistry2021,30,4:3
6Photothermal and pH dual-responsive self-healing coating for smart corrosion protection显示文摘A novel self-healing coating with photothermal and pH dual-responsive properties has been designed to protect carbon steel against corrosion by loading the stimuli-responsive microcapsules into a shape memory epoxy coating. The sandwich-like microcapsules were based on reduced graphene oxide/mesoporous silica(r GO@MS) assembled with a p H-responsive poly(N,N-dimethylaminoethyl methacrylate)(PDMAEMA) layer, and were loaded with benzotriazole(BTA) inhibitors(abbreviated as rGO@MS-P-BTA). Under near-infrared(NIR) light irradiation, the prominent photothermal effect of rGO could not only elevate the coating temperature to activate the shape memory effect and close the coating scratch, but also facilitate the release of corrosion inhibitors to suppress the corrosion activity. Moreover,the PDMAEMA as a p H-driven “gatekeeper” realized the controlled release of BTA from microcapsules at acid conditions. The surface morphology analysis, electrochemical impedance spectroscopy(EIS), and scanning electrochemical microscopy(SECM) were performed to evaluate the self-healing performance of the composite coatings. The results showed that the combination of NIR light and p H-responsive selfhealing effects endowed the coating with short healing time and prominent healing efficiency.Yao Huang Panjun Wang Weimin Tan Wenkui Hao Lingwei Ma Jinke Wang Tong Liu Fan Zhang Chenhao Ren Wei Liu Dawei Zhang 2022Journal of Materials Science & Technology2022,,12:2

9Multi-action self-healing coatings with simultaneous recovery of corrosion resistance and adhesion strength显示文摘In this study, a new self-healing strategy that can simultaneously recover the corrosion resistance and the adhesion strength of coatings was introduced. The coating was based on a shape memory epoxy resin containing ethylene vinyl acetate(EVA) microspheres loaded with Ce(NO_(3))_(3)inhibitors, and was cured at a relatively high temperature to facilitate the fusion of adjacent microspheres for a strengthened self-healing effect. The electrochemical impedance spectroscopy(EIS) and scanning electrochemical microscopy(SECM) results demonstrated that the shape memory effect of epoxy matrix, the filling of molten EVA microspheres as well as the release of Ce(NO_(3))_(3)inhibitors contributed synergistically to suppress the corrosion reaction at the coating damage. After healing, the low frequency impedance modulus of the coatings containing Ce(NO_(3))_(3)-EVA microspheres was three orders of magnitude higher than that of the blank epoxy coating. The adhesion strength of the coatings containing Ce(NO_(3))_(3)-EVA microspheres on the metal substrate was also largely repaired thanks to the strong bonding effect of the EVA microspheres.Chenhao Ren Yao Huang Wenkui Hao Dawei Zhang Xiejing Luo Lingwei Ma Jinke Wang Thee Chowwanonthapunya Chaofang Dong Xiaogang Li 2022Journal of Materials Science & Technology2022,,6:2

15Improved particle swarm optimization based on particles' explorative capability enhancement显示文摘Accelerating the convergence speed and avoiding the local optimal solution are two main goals of particle swarm optimization(PSO). The very basic PSO model and some variants of PSO do not consider the enhancement of the explorative capability of each particle. Thus these methods have a slow convergence speed and may trap into a local optimal solution. To enhance the explorative capability of particles, a scheme called explorative capability enhancement in PSO(ECE-PSO) is proposed by introducing some virtual particles in random directions with random amplitude. The linearly decreasing method related to the maximum iteration and the nonlinearly decreasing method related to the fitness value of the globally best particle are employed to produce virtual particles. The above two methods are thoroughly compared with four representative advanced PSO variants on eight unimodal and multimodal benchmark problems. Experimental results indicate that the convergence speed and solution quality of ECE-PSO outperform the state-of-the-art PSO variants.Yongjian Yang Xiaoguang Fan Zhenfu Zhuo Shengda Wang Jianguo Nan Wenkui Chu 2016Journal of Systems Engineering and Electronics2016,27,4:1
