| description | In this paper, a series of Fe<sub>3</sub>O<sub>4</sub>/MoS<sub>2</sub>/NiS composite electrodes were synthesized by a simple coprecipitation method. The influence of different ratio additives (MoS<sub>2</sub> and NiS) on the performance of iron anodes for Ni-Fe batteries was systematically investigated. In this paper, the mixed alkaline solution of 6 mol/L NaOH and 0.6 mol/L LiOH was used as electrolyte, and sintered Ni(OH)<sub>2</sub> was used as counterelectrode. The experimental results show that the MoS<sub>2</sub> and NiS additives can effectively eliminate the passivation phenomena in iron electrodes, reduce the electrode polarization, and increase the reversibility capacity. As a result, the Fe<sub>3</sub>O<sub>4</sub>/MoS<sub>2</sub>/NiS composite electrodes exhibit a high specific capacity, good rate performance, and long cycling stability. Especially, the Fe<sub>3</sub>O<sub>4</sub>/MoS<sub>2</sub> (5%)/NiS (5%) electrode with a suitable ratio of additives can provide excellent electrochemical performance, with high discharge capacities of 657.9 mAh g<sup>−1</sup>, 639.8 mAh g<sup>−1</sup>, and 442.1 mAh g<sup>−1</sup> at 600 mA g<sup>−1</sup>, 1200 mA g<sup>−1</sup>, and 2400 mA g<sup>−1</sup>, respectively. This electrode also exhibits good cycling stability. |
