| 1 | Research progress in electrospinning engineering for all-solid-state electrolytes of lithium metal batteries显示文摘Owing to safety issue and low energy density of liquid lithium-ion batteries(LIBs),all-solid-state lithium metal batteries(ASLMBs)with unique all-solid-state electrolytes(SEs)have attracted wide attentions.This arises mainly from the advantages of the SEs in the suppression of lithium dendrite growth,long cycle life,and broad working temperature range,showing huge potential applications in electronic devices,electric vehicles,smart grids,and biomedical devices.However,SEs suffer from low lithiumion conductivity and low mechanical integrity,slowing down the development of practical ASLMBs.Nanostructure engineering is of great efficiency in tuning the structure and composition of the SEs with improved lithium-ion conductivity and mechanical integrity.Among various available technologies for nanostructure engineering,electrospinning is a promising technique because of its simple operation,cost-effectiveness,and efficient integration with different components.In this review,we will first give a simple description of the electrospinning process.Then,the use of electrospinning technique in the synthesis of various SEs is summarized,for example,organic nanofibrous matrix,organic/inorganic nanofibrous matrix,and inorganic nanofibrous matrix combined with other components.The current development of the advanced architectures of SEs through electrospinning technology is also presented to provide references and ideas for designing high-performance ASLMBs.Finally,an outlook and further challenges in the preparation of advanced SEs for ASLMBs through electrospinning engineering are given. | Manxi Wang Yaling Wu Min Qiu Xuan Li Chuanping Li Ruiling Li Jiabo He Ganggang Lin Qingrong Qian Zhenhai Wen Xiaoyan Li Ziqiang Wang Qi Chen Qinghua Chen Jinhyuk Lee Yiu-Wing Mai Yuming Chen | 2021 | Journal of Energy Chemistry2021，30，10： | 4 |
| 2 | BENDING OF ORTHOTROPIC SANDWICH PLATES WITH A FUNCTIONALLY GRADED CORE SUBJECTED TO DISTRIBUTED LOADINGS显示文摘Based on the Reissner assumptions, this paper is concerned with the bending analysis of simply supported sandwich plates with functionally graded core and orthotropic face sheets subjected to transverse distributed loadings. First, the expressions of the displacements, stresses and internal forces of the sandwich plate are presented according to the constitutive relations and stress states of the core and face sheets. Then, the solutions of bending equilibrium equations are derived by expanding the deflection w, transverse shearing forces Q x and Q y with double trigonometric series that satisfy the simply supported boundary conditions. Finally, the proposed solution is validated by comparing the results with available elasticity solutions for a square sandwich plate with an isotropic core and finite element simulations for one with functionally graded core. The Young's modulus of the functionally graded core is assumed to be graded by a power law distribution of volume fractions of the constituents, and the Poisson's ratio is held constant. And the effects of the core's top-bottom Young's modulus ratio λ and volume fraction exponent n 0 on the variation of the displacements of the functionally graded sandwich plate are also examined. | Huadong Li Xi Zhu Zhiyuan Mei Jiabo Qiu Yingjun Zhang | 2013 | Acta Mechanica Solida Sinica2013，26，3： | 2 |
| 3 | Electrospinning Engineering Enables High‑Performance Sodium‑Ion Batteries显示文摘As a promising energy storage device,sodium-ion batteries(SIBs)have received continuous attention due to their low-cost and environmental friendliness.However,the sluggish kinetics of Na ion usually makes SIBs hard to realize desirable electrochemical performance when compared to lithium-ion batteries(LIBs).The key to addressing this issue is to build up nanostructured materials which enable fast Na-ion insertion/extraction.One-dimensional(1D)nanocarbons have been considered as both the anode and the matrix to support active materials for SIB electrodes owing to their high electronic conductivity and excellent mechanical property.Because of their large surface areas and short ion/electron difusion path,the synthesized electrodes can show good rate performance and cyclic stability during the charge/discharge processes.Electrospinning is a simple synthetic technology,featuring inexpensiveness,easy operation and scalable production,and has been largely used to fabricate 1D nanostructured composites.In this review,we frst give a simple description of the electrospinning principle and its capability to construct desired nanostructures with diferent compositions.Then,we discuss recent developments of carbon-based hybrids with desired structural and compositional characteristics as the electrodes by electrospinning engineering for SIBs.Finally,we identify future research directions to realize more breakthroughs on electrospun electrodes for SIBs. | Chuanping Li Min Qiu Ruiling Li Xuan Li Manxi Wang Jiabo He Ganggang Lin Liren Xiao Qingrong Qian Qinghua Chen Junxiong Wu Xiaoyan Li Yiu‑Wing Mai Yuming Chen | 2022 | Advanced Fiber Materials2022，4，1： | 1 |
