Abstract.  One-dimensional (1D) nanostructures have been considered as promising electrodes  for advanced electrical energy storage systems such as rechargeable batteries  and supercapacitors in view of their low dimensional properties. Electrospinning  is a  simple, low cost, scalable technology to synthesize 1D nanocomposites with  tailored nanostructures and compositions. In this talk, I  will start with the requirements of battery and supercapacitor technologies in  our society and their corresponding frameworks and mechanisms, followed by a  simple introduction of electrospinning technique. Next, a discussion on how to  use the electrospinning method to synthesize the desired compositions (e.g.,  carbonaceous materials and their hybrids with other active materials such as Sn)  and nanostructured architectures (e.g., core/shell, hollow tubular, porous, and  hierarchical structures) with unique physical/chemical properties (e.g., surface  area, pore volume and conductivity) for energy storage application will be  presented.  Finally, the electrochemical  performance of these electrospun nanostructures will be described.  

 

Biography.  Yuming Chen received his PhD  from the Department of Mechanical Engineering at The Hong Kong Polytechnic  University (PolyU) in 2014. He worked at Nanyang Technological University in  Singapore after graduation and then move back to PolyU as a university  postdoctoral research in Department of Applied Physics. He has published several  papers such as J. Am. Chem.  Soc.Angew. Chem. Int. Ed.Energy Environ. Sci., and Adv. Funct.  Mater His research interests mainly focus on the  design, synthesis and applications of electrospun nanostructures for  rechargeable batteries and supercapacitors.
