Production and Characterization of Rechargeable Composite Nanofiber Membranes

Abstract

Research and development activities on rechargeable lithium-ion batteries are demanded day by day with the increasing demand for portable electrical and electronic devices, as well as the increasing importance of electric cars in the transportation sector. Lithium-ion batteries are preferred by environmentally conscious designers and consumers due to their high energy density and non-toxicity in mobile phones, laptops and small household appliances and due to the low level of CO₂ gas they emit. Ultra capacitors, such as lithium-ion batteries, have high capacity and offer extra fast charging. These ultra capacitors provide weight savings as well as their unique efficiency feature. It has been determined as a result of research that new types of capacitors offer up to 1000 times faster charging compared to ordinary batteries. In this study, polycaprolactone (PCL) and carbon nanotube (CNT) rechargeable composite nanofiber membranes were obtained by nanotechnological electrospinning technique. Material properties were determined by performing morphological (Scanning Electron Microscope-SEM) and mechanical (Tensile) analyzes on the produced composite nanofiber membranes.
