Abstract

In this paper we demonstrate the implementation of multiwalled carbon nanotubes (MWCNTs) and conductive polymer poly(3,4-ethylenedioxythiophene)- poly(styrenesulfonate) (PEDOT:PSS) for the development of highly conductive composite electrode for flexible Zn/MnO2 batteries. The MWCNTs were found to be more effective than graphite. Though more dispersible, carboxylated MWCNTs appeared to increase the resistance of the electrode and decrease the electrochemical performance. The relatively inexpensive MWCNTs represent an advantage over graphite in flexible composite MnO2 cathode.
