Fabrication and activation studies of conducting plastic composite electrodes for redox cells
Abstract
Conducting polyethylene (PE) composite material is fabricated by mixing polyethylene with conducting fillers. Electrical, mechanical, permeation and electrochemical studies show that the PE composite is a good electrode matrix material for the vanadium redox battery. Chemical treatment studies on two kinds of PE composites show that the material with a high graphite-fibre content has good electrochemical activity and stability after treatment. Further cyclic voltammetry and SEM investigations indicate that chemical treatment increases the active surface area of the PE composite.
