| Abstract Scope |
Iron as anode in Fe-Air or Fe-Ni batteries are gaining considerable attention due to their safety, affordability, nontoxicity, and high energy density. However, challenges such as passivation and hydrogen evolution reaction hinder their electrochemical performance. This study aims to develop solutions to overcome these challenges. The bare iron anode initially shows a capacity of 105 mAh/g. It exhibits a sharp capacity fade during cycling, dropping to 10 mAh/g at 50th cycle. With the addition of 5 wt% Bi₂S₃ and 10 wt% FeS as additives, the iron anode shows a significantly improved cycling performance with suppressing HER, retaining 91 mAh/g after 100 cycles compared to an initial capacity of 314 mAh/g. The active material was carbon-coated by pyrolyzing at 750 °C for 2 hours under nitrogen, using glucose as the carbon source. The iron anode, with carbon coating and additives, started at 525 mAh/g and sustained a capacity exceeding 350 mAh/g after 100 cycles, indicating significantly improved performance |
