The influence of carbon additive on the electrochemical behaviors of Fe2O3/C electrodes in alkaline solution

Abstract

Abstract. In this study, Acetylene Black (AB) and Fe 2 O 3 nanoparticles were used as the additive and active materials, respectively for preparing Fe 2 O 3 /AB composite electrode. The effects of carbon additive and binder content on the electrochemical properties of Fe 2 O 3 /AB electrodes in alkaline solution were investigated to find the suitable anode for the Fe/air battery. The results of electrochemical measurements showed that both the AB additive and binder content significantly affected on the electrochemical behaviors of Fe 2 O 3 /AB electrodes. AB additive improves in redox reaction of iron oxide. Increasing the binder content in electrode showed the negative effect in term of the cycleability of Fe 2 O 3 /AB composite electrode.
