Abstract

This work presents the optimisation of an activated carbon ink using Ethyl Cellulose as a binder for application as electrodes in supercapacitors. Effect of variation in the concentration of Ethyl Cellulose binder was explored adopting a commercially available Activated carbon as reference. The resu...
