Abstract:The electrospun fibers mats with nano-micro diameter have high porosity,liquid hold-up,and ionic conductivity. It can be adopted as the electrode separator of power source that has the low resistance,high electric capacity and good safety. The electrospun fibrous of electrode separator that produced by single polymer,modified/blend polymer and organic/inorganic precursors and applied for supercapacitor and Li-ion battery have been reviewed in this paper.

Keywords:electrospinning;separator;polymer;electrolyte;Li-ion battery;supercapacitor
