FABRICATION AND ACTIVATION STUDIES OF CONDUCTING PLASTIC COMPOSITE ELECTRODES FOR REDOX CELLS

Conducting polyethylene (PE) composite material is fabricated by n-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.
