Electrospun one dimensional composite materials as durable anode for efficient energy storage

Abstract

In Li-ion batteries configuration, developing nanostructures is a promising strategy to improve the performance, as nanostructures have short Li ions diffusion length, high electrolyte/electrode contact area and unique chemical and physical properties over their bulk counterparts. Electrospinning is a convenient and scalable technique to pattern 1D nanomaterials electrode for Li-ion batteries. In this thesis, the electrospun one dimensional nanofibers with attractive unique structure, chemical stability and high specific surface area were synthesized and tested as the electrode materials. The electrospun hollow nanofibers help to gain the benefits of higher flux of Li ions across the electrode/electrolyte interface, leading to the facile diffusion of Li ions. The one dimensional characteristics of the nanocomposite provide a good mechanical integrity of the electrode, and it was showed to be a good candidate for the electrode materials.
