英文摘要： With the rapid development of flexible and wearable electronic devices, flexible lithium-ion batteries have become the hotspot and one of frontiers in research field of the energy storage. Till date, the key factors and the main difficulties to realize flexible lithium-ion batteries is to design and fabricate flexible electrode materials with stable and high performance in the condition of repeated bending. In this project, one-dimensional self-standing hierarchically porous highly nitrogen-doped nanofiber networks which suitable for using as promising anode materials in flexible lithium-ion batteries were controllably prepared by using methods of electrospinning, nitrogen-doping, the templates - activation method and carbonization. At the same time, the lithiation mechanism and the mechanism of enhancing electrochemical performance to the electrode by the N element of these anode materials are studied. Project from this proposed research will be of importance for the research and development of the lithium-ion battery industry of our country and novel electrode materials with high performance in flexible lithium-ion batteries.
