TAILIEUCHUNG - Electrochemical behaviors of Fe2O3/C electrodes in alkaline solution
In this study, Acetylene Black (AB) and Fe2O3 nanoparticles were used as the additive and active materials, respectively for preparing Fe2O3/AB composite electrode. The effects of carbon additive and binder content on the electrochemical properties of Fe2O3/AB electrodes in alkaline solution were investigated to find the suitable anode for the Fe/air battery. | Vietnam Journal of Science and Technology 56 (1) (2018) 24-30 DOI: THE INFLUENCE OF CARBON ADDITIVE ON THE ELECTROCHEMICAL BEHAVIORS OF Fe2O3/C ELECTRODES IN ALKALINE SOLUTION Trinh Tuan Anh1, Doan Ha Thang2, *, Bui Thi Hang1, * 1 2 International Training Institute for Materials Science, Hanoi University of Science and Technology, 1 Dai Co Viet, Ha Noi, Viet Nam Department of High Technology, Ministry of Science and Technology, 113 Tran Duy Hung, Ha Noi, Viet Nam * Email: hang@, dhthang@ Received: 27 June 2017; Accepted for publication: 13 November 2017 Abstract. In this study, Acetylene Black (AB) and Fe2O3 nanoparticles were used as the additive and active materials, respectively for preparing Fe2O3/AB composite electrode. The effects of carbon additive and binder content on the electrochemical properties of Fe2O3/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 Fe2O3/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 Fe2O3/AB composite electrode.

INTRODUCTION In recent years, rechargeable lithium-ion batteries have attracted much attention and are considered as the most promising power sources for electric vehicles (EVs) and hybrid electric vehicles (HEVs) due to their unique features. However, the present carbonaceous negative electrode, has not satisfied the requirements of high energy and high power application for EVs and HEVs due to their relatively low specific capacity (. 372 mAh/g for graphite). Thus, lithium ion batteries have been
