Characteristics of Inkjet-Printed Separators in Graphene-Based Supercapacitors

Abstract

In this study, we prepared the separators of supercapacitors on cellulous films and papers by using an inkjet printing technology. Several different ink materials such as carbon nanotubes and metal oxides were introduced and the influence of the base materials used as separator was also investigated. The interface topologies and electric properties of the so formed supercapacitors were investigated by a scanning electron microscope and the measuring system of charge-discharge cycles, respectively.
